Depending on the natural items (trees, water, etc.) and artificial furniture items (chairs, lighting columns and the shelters) and became one of the architectural directions. And major element providing the comfort and harmony between exterior and interior contains and providing the environmental, functional, economic, cultural and social requirements for the space. Landscape Architecture as a direction connect the natural environment and artificial environment surrounding the human due to the functional requirement and environment requirement and as the global direction for the sustainability during the speed improving for all life aspects.The research mentioned as a general hub the concept of the Landscape Architecture and its distinguish between the open spaces and exterior spaces and assess its levels ( architecture versus Landscape, architecture and Landscape, landscape as an architecture) beside the modern direction of the sustainability and the ecological direction.The research took care as a special hub about the concept of the Eco - scape in the landscape architecture. Many dissertations and studies reviewed and discussed for many organization and associations are competent in designing the Eco - scape in their projects and through the discussion the scientific gaps have been determined. From the discussion we have the problem statement of the represented by there is no generalization for the concept of the Eco - scape of Landscape architecture and the most important aspect to achieve and from that the research problem statement determined as shapes of Eco - scape, elements of the Eco - scape, relationship/ principles of the Eco - scape, levels of generating the Eco - scape in Landscape Architecture, the role of the Eco - scape have been achieved in the Landscape architecture.The next steps focus on the theoretical frame elements on projects have been choose from the local projects and achieve the Landscape architecture in one of its three levels. After that analyze the results of the scientific studies and discuss it. Then give the final conclusions in two chapters. The first one contains the conclusions about theoretical frame. The second chapter contains the special conclusions of the implementing in the local case for the concept. Its illustrate the concept of the Eco - scape of the Landscape architecture and recommend it as a local result without a clear mention from the designer by taking care about the related aspects by recommend the designs and on the scape shapes and its natural and artificial elements and the relationships of the formatting and composition of the scape and achieve the Aesthetic environment and functional aspects and encouraging for the sustainable life which is achieve it the Eco - scape in Landscape architecture.

Abstract: اهتم الباحثون بمختلف توجهاتهم لدراسة المورفولوجيا الحضرية؛ لاهميتها في صياغة النسيج الحضري للمدن ومنها المدن الدينية بمختلف المراحل الزمنية، والتي تعكس التسلسل الزمني لتكوين البنية الحضرية للمدن، تعاملت الدراسة مع المورفولوجيا الحضرية من خلال متغيراتها، و| Researchers with their various orientations have been interested in studying urban morphology; for its importance in framing urban fabrics for cities including religious cities on various time stages, which reflects time sequence which forms urban formation for cities, the study have dealt with urban morphology through its variants, as well as with urban formation as one complete formation including both physical side and incorporeal side, research confirmed that the effect of religious factor in religious cities shows in religious monuments, for what it has of regulatory role that works on of the urban fabric’s cohesion, and that role stands out from studying regulatory relations of the urban formation, this is very clear when looking closer at the urban appearance, which differentiates from one city to another through the relation between its morphologic variants, depending on the type of creation factor. All that have determined the research problem : that is the lack of informations about the regulatory role of the religious monument through the variant morphologic stages of the urban fabric’s cohesion of Samarra, the research depends on studying the urban formation as a historical morphologic study for its most important time stages those through which the urban fabric had passed, and determining the most important power centers (religious monuments) which regulates the urban formation, and emphasizing the synthetic properties for clarifying the effect of the religious monuments on the urban fabric’s formulation for religious cities including the Arabian Islamic city in its variant morphologic stages, to verify research’s target in showing religious monuments’ role in the regulation of Samarra’s urban morphology according to the impact that they have as regulatory element for the urban fabric, showing a practical definition for the urban morphology have been a must that it is “the structural appearance for cities, whether they were small or big, including plans, fabric, land uses and the ways which depending upon the appearance’s study have been done, which express the appearance of cities on variant historical stages”, as well as a research methodology that includes construction of informative fundament for the urban morphology and its influencing factors, which divided into formation factors of fabric and ideological proposals which represents the new foundations of cities’ regulation, and laying a clear vision for the research problem, as well as showing reviews of previous studies, with determining the most important methods of morphologic analysis, also the informative fundament includes notion studies for the city from the Islamic perspective through determining Arabian Islamic city as one of the religious cities, and studying its urban fabric and its planning elements to access the definition of religious monument’s notion, and determining Samarra city as a (case study), defining it and determining its religious monuments and its morphologic stages (chapter one and chapter two), then research have drawn theoretical framework’s elements for urban morphology and determining measurements of structural properties (regulators) including both global and local ones for the religious monuments to verify research hypothesis that have been formulated as that “religious monuments have a role in morphology regulation of Samarra City and its fabric’s cohesion”, depending upon that, essential planning have been prepared to analyze the chosen sample (Samarra city), as well as applying measurements and drawing the conclusions (chapter three and chapter four), then research have drawn the final conclusions and recommendations (chapter five). Conclusions have shown the role that the religious monuments have been performed as a regulator for the morphology of urban formation through the regulatory properties (structural) including both global and local ones for its spaces in its various morphologic stages, as well as it have afforded values of indicators for the chosen area that are certified for future development projects to maintain the religious monument role in framing and cohesion of Samarra’s urban fabric.

Research seeks to clarify the sustainable urban development, its concepts, its importance and its components by submit it as a general problem for research, Waters' canals represent as one of the development elements, so The specific problem is " the canals don't be considered as an important component of sustainable urban development of the city." if we consider the canals as natural legacy wich inherited from the current generations to the futuristic generations. Previous literature indicated that it didn't include the study of the role of waters' canals in the morphological urban development for the cities ",this represents the main problem of the research.The aim of the research is to study the waters' canals in Basrah city, diagnosis and specify the role of canals which embody the greatest importance in the morphological urban development of this city. The main research hypothesis is "canals vary in their importance or their role in the morphological development of the cities through their spatial organization or lands uses on the both sides of these canals ".The research followed the analytical method, and put a comprehensive theoretical framework for each of sustainable urban development, waters' canals and urban morphology and Sustainable urban design. To test the hypothesis research through study the spatial organization of Basrah city by using the Arc View GIS 3.3 to see the canals that deserve rehabilitation inside the city. The coaxial map was plotted for the network of the main streets of the city which are parallel to the waters' canals and research assumed that the integrated axis is reflected on the water's canal and thus refers the integration of that canal and it has importance in the morphological development of the city , which must rehabilitated later. Study lands uses which align the important waters' canals by field survey. Do aquestionnaire to professionals to measure words of sustainable urban development and sustainable urban design.The research reached in its practical study to diagnose the main waters' canals in the city which have the more importance in the morphological development of Basrah city , where its result come from the integration and the access to those canals by using major ways of transportation.The results of the program are about twelve canals which gained high values, those canals are " Sarraji Canal , Al Khora Canal , Alashar Canal , Alkhandag Canal , Rebat Canal , Jubailah Canal , Shatt al - Turk canal , the vertical canal on the Shatt al - Turk canal , Baghdad's streets' Canals beside Aljameyaaat district , the canals which paralleled Baghdad's street beside Alsma'i and Alaaleya districts ,alsheeaba's drainage canal and the vertical canal between Al - Sarraji and Al - Khora Canal) ,the research diagnoses and concentrates on the main lands' uses on the Both bankes of those Canals and they are (governmental , commercial and residential and mixed).

Considered that nations have been always known and studied through their culture and civilization, it is reasonable to state that architecture is an important entrance to understand privacy of specific society that have been formed through an interaction among social, economic and other aspects. Today, there is an immense and clear interest in human intellectual and artistic heritage, including those architectural and urban heritage. That is why this heritage - whether it goes back to a near or far time - is getting a special interest among others, because they are considered to be an entrance to study human existence, past, memories from specific time. As a result, it is considered to be his identity that shows human existence. Consequently, to protect that heritage is immensely important for what it is worth. Also, today, it is clear that technology evolved much further than anytime, and it is crucially important to collect all available data, as it plays an essential role and has a crucial effect on our present, and future.Accordingly, It is clear how crucially important to think in a certain way to deal with those building, to protect, revive and work to improve its sustainability and convenience by using advanced techniques and technologies, also to measure how suitable it is to beingpreserved by those techniques. Consequently, reaching to a reasonable and clear method to achieve its preservation and to preserve its historical and various properties. Although, thesis which have dealt with preservation are replicated, those which are general, they have dealt with the problem by using urban filling and renewal or traditional preservation’s methods. Whereas, those other private didn’t consider to adapt a clear method for preservation that achieves coherence and cohesion. As a result, the general axis for the research is identified with : The existence of informative gap in the current method of urban preservation, while the research’s problem is the lack of clarity in the informative knowledge that should be available to achieve the protective preservation (Sustainable) for architectural heritage. Accordingly, that shows the research’s target clearly, that is to identify suitable advanced methods to achieve the protective preservation (Sustainable) for architectural heritage. The research has stated its thesis : Preservation of historical and heritage architectural buildings depends on its capability to suit current and future requirements of society, and to balance the system of forms and values inside the urban scenery and to support it, as well as its capability to success economically and environmentally through using those building functionally.The research depends on analytic and descriptive method, which includes forming an informative theoretical framework about the historical and heritage architectural buildings, preservation, protective preservation (Sustainable) and to brief most important variables and indications for each term. Accordingly, the research has conducted that preservation of historical and heritage buildings is related to design in the first place, and it is possible for creative thoughts and techniques to vary according to the design vision. And analyzing those thoughts within functional variables, as well as temporal and spatial enriching have shown that whenever taking a decision for a functional change, the new function turns up with clarity and purposely, which comes with a clear program and undergoes to the protective preservation’s terms when preserved and directed. In all those buildings who have been preserved, especially the ones designed by famous architects, an advanced reliable techniques have been used, which confirms the protective preservation.When it comes to economic aspects, cost of conduction and sources of investment, the tourism and meaningful attraction as well as how well those preserved building function offer an additional sources of investment as well as the meaningful and iconic aspects which confirms its role in sustaining the building.

It has evolved over the years with the stability of its content where it is essential.The evolution of the concept in the contemporary architecture refers to the importance of the recipient and his reading of the text and architectural diversity of various aspects of Appropriateness such as (function, expression, economy... etc.). From this side the importance emerged to study the concept of Appropriateness and to identify its branches and aspects.the general problem of this research was about “Appropriateness in architecture”. The subject has been emerged in the linguistic and scientific studies so as in architecture to branch out several types and aspects which necessitated narrow down the search.Search been reduced to one type of Appropriateness which is expressive Appropriateness in products of architectural and the study identified the contemporary buildings because the importance of the concept in the current buildings.Research problem Identified as “Lack of a comprehensive objective perception about the concept of expressive Appropriateness in contemporary architectural production and the relationship between the designer intentions and the other indicators of special conceptThe study identified a procedural definition of expressive appropriateness as a "compatibility and degree of proportionality between designer intentions (expressionistic ideas to be delivered to the recipient) with what actually verified in the final product where productions vary in their suitability for designer intentions. Hence the aim of the research is to form an objective and comprehensive framework for expressive appropriateness properties and how they are invested to achieve the goals that are supposed expressive presence in the production and measure the achievement of goals expressive on elected projects for practical application.The hypothesis of this research has been Formed as expressive appropriateness actually realized in the architectural production through compatibility between intentional designer in output expressed goals and what Verifier in production, which depends on private recipients readings, as the designer intentions means goals plus the results of indicators to achieve expressive appropriateness ". The research found the existence of diversity in expressive goals for designers with a variety of mechanisms and realized Systems and configurable characteristics used in production. It was also found the presence of expressive appropriateness between the goals of designer and the receiver reading in varying degrees Key words : appropriateness, Expressive appropriateness, the goals of expression, intentions of designer, contemporary architectural production.

Abstract: شكلت طبيعة التغيرات في العوامل الثقافية والاجتماعية خلال القرون السابقة اساسا في قدرتها على ابراز الخصوصية الاجتماعية والثقافية والتعبير عن هوية البيئة المحلية وبالتالي نتاجها للعمارة.وباعتبار العمارة هي نتاج حضاري انساني ضمن منظور فكري يعكس تغيره الفكر | Formed the nature of the changes in social factors during the previous centuries mainly problematic in its ability to highlight the cultural, social and expression of the identity of the local environment and thus their productions of Architecture.As architecture is the product of a civilized humanist within the perspective of intellectual reflects the change of human thought , and society in all its details , connections , relationships , values, customs and traditions , and follow through literature earlier addressed the issue of housing in Baghdad and specific showing the direct relationship between social factors ( customs and traditions) and housing , and given the importance of the events experienced by Iraq, which affected the various social and cultural aspects of society , including the architect in general and housing in particular, for the purpose of enriching the knowledge at hand about the cultural and social aspects and their impact on architecture Iraqi contemporary and in particular architecture housing in Baghdad , to get to an integrated view on the march the evolution of the traditional house in Baghdad and influenced by social factors Housing is one affected by the architectural phenomena since ancient times and still any changes or developments in intellectual , cognitive and humanitarian... etc... Because of the growing change in the social factors ( customs and traditions) in terms of the priority needs of the individual ( Alsaikologih ) towards the needs of the Assembly ( social and biological ) in the dwelling specifically what explains the weak capacity of his production to create adaptations appropriate for the needs despite their importance in the reality of housing for the lack of agreement with the priorities static or the importance of achieving them.Ensure that research approach a number of steps adopted search in cultural and social factors of Iraqi society , and the reflection of these factors on the architecture (housing in particular) and down to determine the vocabulary of change in the nature of man, and the change in the nature of society and the change in local architecture down to the change in the house of traditional , put hypotheses and tested in practical application down to the findings and conclusions.Research found that the change in the House today was the result of cultural change happening because of social change, as a result of the changing needs of society and the requirements which impact on the design of the house contemporary and at the level of relations within the spaces and function and shape of the space through the emergence of modern ideas and attention to the achievement of individual needs at the expense of the needs of the Assembly.

Abstract: Imprint is considered as a language during the last four decades. contemporary studies had presented this trend through different approaches which delt , primarily ,with identidy as semantic expression in all events, the aim was to create continuity and links with social structures which represent the vessel contains human culture.hence; there was a strong need to verify various methods that extend the space surrounding continuity context. Therefore touch methods are clearly important as an indicator in suggestive and expressive ways.the imprint doesn’t react individualy unless it is used through the logic of dialogue. This meant that touch is atool of semantic ideas which depends on formalistic expressions using interpretive dimension of imaginativevisions to create designer special that imprint specific to him signs that form a constructive texts which meet collective agreement and represent an individualistic quality of its own. This approach requires a presentation of knowledge which is concerned with continuity.By defining the touch and reviewing available of this aspect in order to create a viable approach to it, the research is discreeted towards utilization of touch as one stage of strategies to achievebcontinuity in contemporary architecture.Various studies we've reviewed which delt with social and expressive dimension as well as methodogical approach. the research area was narrowed down to.studies delt with architecturer's persortality throught his touch on his design , as though studies that analys his proudection ccording to his surrounding area. The aim of this research was to reveale theoretical vision that describes.The theoretical content of this research has identified three elements of significance to this problem(imprint form, the characterizes of the imprint, and imprint aim).Unperfectlly understanding to imprint as atheme generally and don’t enable it take important position in architectures specifically.By this we define touch's work as a way to express about the architecture him self alone which depend on two aspect on of is Hypothitical depends on understand touch from the designer , and the other one is shape aspect which try to make connection between the imprint and the designer personality in aime to creat expressional dialogue delt with recipient continuouity from aside and from the other side understanding the hidden messeges that have sent through imprint.Application of the theoretical presentation considered for first one aspect(out of three). Hypothitical consideration suggected singular change for the first one aspects and binary change for the last two aspects. Measurments methods was developed to determine change and applied to selected sample to determine readings intellectual and formal levels. General and specific methods were reviewed with the aim of exploring the stated hypothesis. The first results and findings were presented regaring three fields. The variability of the framework , the results of measurements and finally general consideration of the wholenesof the approach. Recomandation were presented and fields of further reserchs where identified.

Abstract: ادى تطور التكنولوجيا الرقمية الى توسيع القد ا رت التصميمية لدى المصمم المعماري وخاصة في مجال توليد الاشكال المنحنية وذات التعقيد الشكلي والتي اتصفت بعدم امكانية او صعوبة القدرة على تنفيذها بالطرق التقليدية للبناء مما ادى الى ضرورة البحث عن طرق واساليب جدي | The development of the digital technology has led to the expansion of design capabilities of architects, especially in the field of generating curved forms with formal complexity which was unattainable with the traditional methods of construction, thus resulting in the need to research for new executive ways and methods to realize them physically, and so Digital Fabrication has appeared in architecture as a contemporary concept that grew over the past two decades. Despite the emergence of a number of theses that tried to explain it in the field of architecture, none of them gave this concept a comprehensive definition or dealt with it in depth, hence the concept of (digital fabrication in architecture) appeared in a general framework that recognizes the concept and its beginnings in the other fields and the stages it went through to reach the field of architecture, for the purpose of reducing the limits of research to the specific frame which is summarized in(the role of digital fabrication as a link between the design process (modeling) and the realized architectural product which is represented by the fabricating of building parts, and by thorough searching of studies which took into consideration the existence of the above - mentioned three - way relationship between (designing, fabrication, and production), the research problem was derived, which states that (Lack of previous knowledge in forming a comprehensive conception describing how to achieve digital fabrication and its impact in contemporary architectural production) and thus to reachthe goal of the research (creating a comprehensive conceptual framework regarding how to achieve digital fabrication in the field of architecture and its impact in contemporary architectural production), and achieving this approach requires the construction of a theoretical framework consisting of four main units; The methods of fabricated digital design generating, Digital fabrication techniques, production strategies and to clarify its impact in contemporary architectural production, and as such is the first phase of solving the research problem. While The second phase deals with application procedures marked by the formulation of hypotheses and consisting of two main assumptions (the realization of digital fabrication depends on the integration of the levels of each of the following, the methods of fabricated digital design generation and digital fabrication techniques and production strategies) The second premise is (the adoption of Digital Fabrication with its three levels affects the contemporary architectural product positively) and then determining the basic requirements for the application by selecting the method of data gathering and the type of measurement used as well as defining the application sample marked by a range of contemporary global projects by some of the best architects who rely on digital fabrication in the production of their buildings and which are executed in the real world and belong to the same era which is the last five years and has a similar functional approach for the purpose of highlighting the formal and structural aspects.The third phase, focuses on discussing the results, analyzing them and determining the validity of the hypotheses and then defining the final conclusions which were raised in two axes, first axis focused to clarifying the effectiveness of the theoretical framework in achieving digital fabrication and its role in bridging the gap between representation and construction and its impact in the product that was achieved within the formal, structural and professional aspects, while the second axis focused on the conclusions drawn from analyzing the results of the application, which indicated the possibilities and special effects that distinguish each one. And so the research has contributed a cognitive addition to the field of architecture and defined recommendations and future horizons forpossible researches keywords Digital fabrication, ,digital design methods, digital techniques, digital.

Through the criticism of the trends which try to solve this problem and which can be determined in analysis the real adaptations of the residence unit and by extracting data from the real residential production, or the specialized research studies which may prepare the necessary indexes to develop, a reference is made to the weakness of what has been presented by both directions in this aspect due to the change of the balance of the properties of the resident needs in the elevation increasing towards some apparent items of self needs in a way that explain the weakness of the ability of real production affected by these trends to create the suitable adaptability to realize other needs despite of its importance. the study also points out the weakness of these studies which tried to solve these problems by independently focusing its various items from the input of its extracted induces in the residential reality whether because of the disagreement of these items or the contrast of its indices with the priorities of real residential needs or the indices of its realization.On these bases, the study suggested a compromizing mechanism that depends on presenting the indeces that can realize the balance between realizing different needs of residence and the priorities of resident wills in the elevation based on an approach that depends on the use of the potentials of both real and research aspects in presenting its special indices and to examine the ones presented in the second aspect.The suggested mechanism, therefore presented its approach within a group of procedural steps depending first on extracting the indices of the residential reality. Being a representation of the resident wills and his priorities , these indices are compared with those extracted from the realization of different needs of residence.The results of the comparison can express the ability of research aspect on presenting its indices applicable in the residential reality whereas the deference may point out the extent to which the vision varies towards the priorities of residential need of the mechanisms of their realization between the two aspects and the ability of the residential reality to create its own indices by its own realistic mechanism and priorities. It also express the styles that can be adopted to inhance the efficiency of the research aspects in this respect. To practically test the suggested mechanism, it has been applied in the urban residential production in Mosul according to the prepared approach where the extracted practical conclusions showed the efficiency of the mechanism in extracting the realistic indices to realize the different needs in the residential reality and the effecting changes. The study also showed the limits of contribution and the evaluation of the architectural role whether in practical design or in research supporting studies in supplying this production with the additional indices to develop the residential production and the factors of success and failure in their role. The research concludes with some recommendations which focused on activating the cooperation between the two mentioned aspects and the role of architectural design in practice as an active joint capable of inhencing the transfer of indices between the two parties.

Abstract: Since the building envelope represents the main axis for all thermal controlling processes being the insulation of internal environment from the external one, and as a responsive and adaptable with the external changes through its thermal conduct by preventing external effects.In addition, it includes all the external means that ensure comfort for occupants represented by walls, roofs, grounds, and all vents (doors and windows) whereas the external walls represent one of the most important structural elements that have a direct effect on the thermal performance of the building.In order to achieve the aim of the research the experimental approach and style of analytical study were adopted. The current study included two main aspects : first, the theoretical side : Which included the time delay factor calculation and cooling load depending on the Radiant Time Series (RTS) theory that achieve accurate and detailed results and ease of application The theoretical results for each hour were calculated using a new version of Mat lab program. While the second aspect included the practical test and measurement where three test chambers have been constructed as samples for the purpose of study located in the department of the mechanism and productivity of Al - Fao Engineering in Altajiat in Baghdad. The three chambers were constructed with dimensions (3000mm x 2250mm) and (2250mm) height without windows and the ceilings and walls were made the only effective resource in changing the level of thermal comfort inside it. The longest side of the three test chambers was directed towards the east - west. The walls of the first chambers have been made of perforated brick , the second chamber of thermo - stone, the third of double glazing units. The ceilings of rooms were treated by materials of humidity contraindications with thermal insulators are quite similar in order that the comparison would be only confined to the walls, and to identify the effect of the air cavity (100mm,25mm) when using it with the different materials of cladding such as ( white marble, black marble, stone of Ba Athra, composite - panel).Two iron structures were made in order to exchange the termination materials and the thickness of the cavity as well as each chamber has been equipped with (one ton) air conditioning with a same cooling degree for each chamber, the devices were connected by a scale to measure the amount of energy spent in each chamber with a fixed temperature inside, in addition to thermal sensors fixed on the inner and outer surface of the wall and in the inner space, consequently the energy exchange was considered as an evidence and indicator to the differentiation among the materials used and types of cavities in double walls. The theoretical and practical results made a good rapprochement, whereas the first test chamber (in which Brick is the material construction of the walls) has made a contrast ratio between the theoretical calculations and practical application for the electric power about 23.6%, while the second test chamber (in which thermo - stone is the material construction of the walls) has made a contrast ratio for the electric power about 22.3%. Consequently, Results of the study showed that the Exterior cladding material by using perforated brick of 120 mm thickness recorded the highest proportion of the economy in the amount of electric energy which considered to be the best thermally. However, Exterior cladding material (such as black Marble) and cladding materials with fewer block (such as composite - panel) represent the worst thermal performance because they made the lowest economic proportion of the amount of electric power. Besides, the thermo - stone material as a material of walls constructing has made an economic ratio of electric energy higher than the one made by the 240mm thickness perforated brick. The research, As well as, concluded that increasing the thickness of cavities from 25mm to 100mm may reduce the consumed amount of electric power about 6.6% when the construction material for the walls is 240 mm thickness perforated brick and 4.3% when the construction material for walls is thermo - stone.

The region that was selected for performing the research is Middle East region because it’s great and wide region and includes Iraq. Remote sensing information that is used in this research includes satellite image data taken from Meteosat satellite. ERDAS package is used to produce the contour model on satellite images.Satellite weather images for three sequence days were taken and operated on, active contour models were classified. These phenomena represent clouds in different types. This type of contour is fast and easy to create as well as discover the clouds edge more accurately. Accordingly contour intervals that are 30 gray level are found to detect accurate features in images.The other part of the research classifies contour models to many classes to discriminate clouds type and clearing the type according to color,that found in image. Where a low cloud represents high color value and refer to dark color. This refers to the contour line classified according to color degree from 0 to 240 gray level, compared the satellite image that was taken from practical experiment with others to find the changes in images and the results are clear.

Abstract: Silica nano particles were prepared from Iraqi rice husk (al - Najaf province) by precipitation method. Rice husk (RH) was treated with two different concentrations of inorganic acid (i.e. 1 & 3 N HCl) then burning at 700 °C under two heating rates. Chemical composition of rice husk ash (RHA) determined by X - Ray fluorescence (XRF) was contained about 89.5 wt% and 95.2 wt% SiO2 by treatment with 1N HCl at 10 and 5 °C/min heating rates for 3 hrs, respectively. While, XRF analysis was given 97.5 wt% SiO2content in RHA by treatment with 3 N HCl at 5 °C/min heating rates for 2 hrs. 3N HCl and heating rate at 5°C/min seems to be the best method to reduce the metallic ingredients and to obtain highly purified nanosilica powder at a purity of 98.9 wt%.The prepared nanosilica was also characterized by X - ray diffraction (XRD), BET surface, Fourier transform infrared spectroscopy (FTIR) and Atomic Force Microscope (AFM), in order to investigate its properties.X - ray results revealed a strong single beak of 2? at about 22° with an amorphous phase. Surface area was measured for nano silica to be 298 m2/g. The average diameter of prepared nanosilica is 89.58 nm as obtained by AFM analysis. Rice husk is seen to be a frugal waste material, high silica content, and it will be able to apply as a natural source of silica for preparation the zeolite - Y catalysts rather than burnt or dumped it as waste, causing environmental and health problems. On the other hand, the commercial source of silica (i.e. Ludox As - 40) is industrially used with other materials for synthesizing the zeolite type - Y catalyst and economically it has an expensive cost. Hence, it is essential to find out another pathway for silica source.This work deals with the replacing of costly commercial precursors of silica by a cheap natural nano - source silica from Iraqi RH. As such this study focuses on the optimization of percentages of natural and/or commercial silica applied within either seed gel or feed stock gel in the zeolite - Y synthesis process in order to investigate the effect of the nature of the silica used on both the structural properties of produced of Y - catalyst as well as on the catalytic performance of these catalysts in hydrocarbon cracking reactions forimproving the production catalytic activity and selectivity. Commercial zeolite - Y catalyst was laboratory prepared by means of commercial silica source and named as “A” sample, whereas other four samples of zeolite catalysts were successfully synthesized with a desired zeolite - Y phase and so - called “B, C, D and E” using different percentages of natural silica source. All the achieved samples are investigated by characterization techniques (i.e. XRD, BET - surface area, Pore volume, FTIR SEM, AAS, and EDX). The synthesized HY - catalyst samples were catalytically tested in the cracking of Hexane (C6H14) through an experimental cracking rig, and the reaction products were analyzed by GC. The performance of Iraqi RH zeolite type - Y catalysts was compared with the commercial lab HY - catalyst. Catalyst B prepares from only natural nanosilicasource and in comparison with other synthesized Y - catalysts; it gives the best catalytic behavior with 98 - 95 mol% conversion together with the selectivity domination of isomer and normal paraffin within the reaction products during more than 2 hrs at 450 °C. This result confirms that the use of natural silica source can be enhanced the catalytic properties of zeolite type - Y catalyst.

A rotating cylinder electrode (RCE) system were used to study the potentiostatic polarization experiments, under turbulent flow conditions, using 3.5wt% brine solution as electrolyte at different temperatures (298, 308, 318 and 328)K and rotating speed of (0, 100, 200, 300 and 400)r.p.m. at each temperature.Similar experiments were carried out in 3.5wt% brine solution using CO2 gas at (32 ml/sec) flow rate.Corresponding experiments by weight loss were carried out in 3.5wt% brine solution with compunds of : - 1. Kerosene + 10V% brine solution.2. Gas oil + 10V% brine solution. At 328Kand flow rates of (0 and 400) r.p.m.3. Similar experiments were carried out in kerosene + 10V% brine solution at (298, 308 and 318)K and static condition speed of (0) r.p.m at each temperature.4. Experiments were carried out in pure kerosene at a temperature of (298 and 318) K and speed of (0) r.p.m.All above experiments were carried out with and without CO2 gas.The results indicated that the corrosion rate of carbon steel was increased in presence of CO2 gas.The anodic dissolution kinetics were activation control processes affected by temperature.The activation energy of carbon steel with CO2 gas system (2.87 - 1.8) Kcal/mol at different r.p.m. was lower than that without CO2 gas system of (11.4 - 1.7) Kcal/mol at different r.p.m.The corrosion potentials without CO2 gas were shifted to the noble direction with increasing flow rate at a constant temperature, whereas such potential were shifted to the less noble direction with increasing temperatures at a constant speed. However, the corrosion potential with CO2 gas was more noble than that obtained without CO2 gas.The corrosion rate is increased with increasing temperature and velocity. The results indicated that the corrosion rates of ( gas oil +10V% brine solution ) are higher than that of (kerosene +10 V % brine solution) with and with out CO2 gas, and the corrosion rate of pure kerosene is lower than that of (kerosene+10V% brine solution) with and without CO2 gas.In the presence of CO2 gas the results indicated that corrosion rate increases due to continuous dissoultion of iron ion and formation of weak carbonic acid. The carbonic acid accelarteed corrosion rate and affected carbonate and hydrogen ion, which increased the cathodic reactions on the metal surface.

A laboratory unit was constructed for this purpose, where a versatile reactor setup required "high pressure stainless steel reactor of 0.018 m i.d.×0.76 m height", in which experiments could be carried out under different modes of operation. The effect of key parameters that influence on the performance of trickle bed reactor (TBR) for CWAO and PP - CWAO is studied in a steady - state operation to provide a basis for comparison with periodic experiments and kinetic measurements in TBR under constant operating pressure (0.1 MPa) throughout Initial phenol concentration (0.84 - 1.5 g/L), liquid hourly space velocity (1.16 - 19.87 h - 1), superficial gas velocity (0.163 - 0.655 m/s), and bed temperature (30 - 80oC) for CWAO. Hydrogen peroxide concentration (5 - 40%) and feed rate (0.0499 - 0.1465 L/h) for PP - CWAO at constant liquid hourly space velocity (1.16 h - 1), initial phenol concentration (1.35 g/L), superficial gas velocity (0.163 m/s), and bed temperature (80oC).In periodic operation, the effect of cyclic parameters is investigated in a broader range of cycle period (5 - 180 sec) and split (0.2, 0.5 and 0.7) for both liquid flow and hybrid modulation under some of the conditions chosen on the basis of the steady state results for PP - CWAO.The results showed that the CWAO and PP - CWAO of phenol are kinetically controlled. In CWAO, LHSV and air flow rate have a slight effect on the phenol conversion, whilst they have a positive effect on the rate of reaction. The conversion and reaction rate of phenol increase with increasing initial phenol concentration and bed temperature, but they have a little pronounced effect in the range of temperature. The highest phenol conversion (75.26%) was obtained over Pt/? - Al2O3 at LHSV=1.16 h - 1, bed temperature=80°C, air flow rate=10 L/min and initial phenol concentration=1500 ppm.For PP - CWAO, the promoting effect of hydrogen peroxide was less marked in the range (5 to 25) %H2O2 concentration while at (35 - 40) %H2O2 concentration, the removal efficiency became more pronounced where the phenol conversion enhanced from 73.26% conversion at 25% H2O2 to 88.88% conversion at 40% H2O2. Hydrogen peroxide flow rate has a negligible effect on the removal of phenol. According to the kinetic results, the reaction kinetic was pseudo first order with respect to phenol concentration, (0.3) order with respect to oxygen, and the apparent activation energy equals to (19.8247) kJ/mol. The rate expression for CWO is - r_ph= C_ph^ For periodic operation, the time average conversion enhancement is indeed quite considerable in liquid flow modulation as split is lowered from steady state (? =1) to a value of (? =0.5) and reached as much as 6.66 % over the steady state at cycle period (?_p)= 15 sec; which is close to the hybrid modulation, where enhancement reached to 6.91% at ? =0.2 and (?_p)=5 sec.Intermediate compounds were analyzed for CWAO and PP - CWAO in steady state operation. Four intermediate compounds were indicated, namely oxalic acid, acetic acid, formic acid and maleic acid (carboxylic acid). Acetic acid being the main refractory intermediate in the catalytic oxidation of phenol at the operating conditions employed for CWAO process in steady state operation. The PP - CWAO of phenol in steady state and periodic operation has a positive impact on the intermediate compound mineralization as compared with the CWAO in steady state operation. In the modeling part, a suitable reactor scale model is evaluated and extended to predict the performance of TBR under the employed conditions. The model was solved numerically by finite difference approach with a semi implicit solution of the differential equations. The simulated results for steady - state and periodic operation (liquid flow modulation) performance showed that the expected trends in performance enhancements as experimental results. The experimental data results showed the relative error for the conversion (1.22 - 8.9%) in the broad range of experimental.

Fuel regulations continue to tighten worldwide in response to the need to cleaner air and refiners meet these regulations at a very significant cost. The need to cut the operational and capital costs has necessitated a renewed look to the non - hydrogen, low temperature and pressure processes for producing ultra low sulfur fuels.Non - conventional approaches for ultra low - sulfur fuels belong either to oxidative or a selective adsorption routes. The present research focuses on a batch adsorption desulfurization process for diesel fuel containing 580ppm sulfur, based on physical adsorption of refractory sulfur compounds on activated carbon (AC). The effects of time (0 - 3.5 hr), temperature (30 - 70 °C), diesel to AC ratio (2 - 10 ml/gm), AC particle size (0.2 - 1.44 mm), mixing velocity(100 - 1000 rpm), and initial sulfur concentration (280 - 580ppm) in commercial diesel fuel on the desulfurization efficiency were studied. The residual sulfur concentration in diesel fuel was decreased from 580 to 247 ppm, corresponding to a desulfurization efficiency of 57 %, at best conditions of 2.5 hr contact time, 50 ?, 2ml diesel/gm AC, 0.8 mm AC particle size, and 1000rpm mixing rate. The sulfur adsorption dependency on contact time and initial sulfur concentration in commercial diesel fuel (280 - 580ppm) were studied. Different kinetic models : Pseudo - first order (PFO), pseudo - second order (PSO) and intraparticle diffusion models were applied to fit the experimental data. The results of the kinetic analysis showed that the pseudo - first order model underestimates the equilibrium sorption capacity by about 33%. However the pseudo - second order model has succeeded in predicting the equilibrium sorption capacity with correlation coefficient, R2 = 0.995. The experimental adsorption isotherms were correlated by Langmuir and Freundlich models. The results indicated that Freundlich isotherm exhibits the best fits for the adsorptive desulfurization of diesel fuel with correlation coefficient (R2) of 0.989 as compared with the Langmuir model ( ). The adsorption intensity as estimated from the Freundlich isotherm is larger than one which is indicative of physical adsorption.

Aerobic biological treatment is applied for synthetic wastewater containing 2 gm/L methanol. Important operating parameters in this system are the sludge volume, temperature, pH and total time. Investigating these parameters can establish sufficient microbial mass for efficient treatment. The treatment is carried out under various conditions of temperature (20, 30 & 40) 0C, pH (6, 7 & 8), total treatment time (2, 3 & 5) days and for different sludge volume (100 ,280 & 450) ml. The best volume used is 280 ml from the prepared activated sludge which gives best removal down to 160 ppm. Treated wastewater samples were collected at different time and stored in deep freeze.The stored samples are analyzed for methanol content by direct injection to Gas - Chromatography. From the experimental investigation results, it has been shown that the aerobic biological treatment is efficient in reducing methanol concentration in treated wastewater. The addition of 280 ml of sludge to seven liters of synthetic wastewater gives maximum removal of methanol. The results are analyzed mathematically. The experimental data collected by this sludge volume are successfully fitted to a second order polynomial empirical correlation.The most favorable operating conditions for the 280 ml sludge volume are 400C temperature, pH = 6.8 and 102 hr total treatment time with 30h aeration.On the basis of the best conditions obtained the empirical correlation, is obtained as follows : Y = 14616.62 - 17.4202X1 - 10.6311X2 - 3592.75X3+ 0.028335 - 0.159515 + 254.532X32 - 0.1263X1X2 + 0.452606X1X3 + 1.7638X2X3. Where : X1=Treatment time. X2=Temperature.X3= pH Average absolute error =10.8 % Correlation coefficient =0.98.

Abstract: كلا من الصناعة الكيميائية (chemical industry) والبحث الاكاديمي (academia search) للمذيبات البديلة يجب ان تلبي متطلبات التكنولوجيا النظيفة (cleaner technology) حيث ان المذيبات الاكثر استخداما على نطاق واسع هي المتطايرة والضارة. في العمل الحالي، تم تحقيق | Both chemical industry and academia search for alternative solvents to meet the cleaner technology requirements since the most widely used solvents are volatile and harmful. In the present work, the technical feasibilities of room temperature ionic liquids (RTILs) as bulk liquid membranes (BLM) for phenol removal from Industrial Wastewater was investigated. Room temperature ionic liquids (RTILs) used as a membrane mainly due to their properties of low vapor pressure, low volatility and they are often stable. Four ionic liquids with high hydrophobicity were used : 1 - butyl - 3 - methylimidazolium hexafluorophosphate [Bmim] [PF6], 1 - butyl - 3 - methylimidazolium bis(trifluoromethylsulfonyl) imide [Bmim][NTf2], 1 - Ethyl - 3 - methyimidazolium bis(trifluoromethanesulfonyl) imide [Emim][NTf2] and 1 - hexyl - 3 - methylimidazolium hexafluorophosphate [Hmim][PF6], in which, phenol Extraction efficiency and stripping efficiency were studied. The effect of different types of anion and hydrophobicity of the ionic liquids on the phenol extraction and stripping efficiencies were investigated. Different operating parameters of feed phase pH, feed concentration, NaOH concentration were studied. In addition to the effect of single ionic liquid (SILs) and binary mixtures ionic liquid (BMILs) on the phenol extraction and stripping efficiencies were also studied. The study shows that highest phenol extraction and stripping efficiencies were [Bmim][NTf2], [Bmim][NTf2+PF6] and [Emim][NTf2], [Bmim+Emim][NTf2] respectively. Phase equilibria for the extraction of phenol from industrial wastewater using ionic liquid membranes was determined. The efficiency of ten new solvents as a selective ILs solvent in the extraction of phenol from wastewater was investigated. Data have been estimated experimentally for ten systems containing, phenol + water as a common component liquid and + ten IL solvents. The consistency and accuracy of the tie line data were evaluated using three correlation namely, Bachman, Hand, and Othmer and Tobias. The Plait Point for each ternary system was estimated. Among the ILs used to extract the phenol from wastewater, [Bmim][NTf2+PF6] shows the highest selectivity and distribution coefficient. The liquid - liquid equilibrium data have been predicated using electrolyte non - random - two - liquid (e - NRTL) model and extended UNIversal - QUAsi - Chemical (e - UNIQUAC) model. The binary interaction parameters have been calculated using Maximum Likelihood Principle technique. The experimental data fitted by the e - NRTL model is more accurate than the e - UNIQUAC model.

Abstract: يشتمل البحث على عمل نموذج رياضي لمفاعل النازلdowner) ) في وحدة التكسير المحفز بالعامل المساعد وان التفاعل يشمل اربع مكونات هي التغذية Gas oil)) والغازات الخفيفة (Light gases) والكازولين (Gasoline) والفحم (Coke) اوما يسمى ب Four lumps model لوصف حركة تفاعل | In this work, mathematical model for downer reactor have been developed, in which a four - lump model is used to characterize the feed and the products, where gas oil cracks to give lighter fractions and coke. The integrated reactor steady state model makes gross assumption about the hydrodynamics, using 4th. order Runga Kutta method. Polymath version 5.1 and Aspen version 7.3 programs are used to solve the simulation model. This model can predict the mixing temperature and pressure profiles at mixer (MxR) chamber; also shows the physical performance and productivity all over the downer height. An interactive excel worksheet is constructed and used as a powerful tool for solving the model equations and studying the effect of any change in operating variables on the unit performance. Also observed the simulated results by using two programs (Polymath and Aspen) and the difference between them especially in temperature , pressure and product yield profile plotted along the reactor length and shows that the results from Aspen are better than Polymath because the first is more advanced and accurate. The operation of downer reactor for catalytic cracking is associated with several important objectives such as feed rate and height, diameter of reactor and amount of catalyst rate as well as the production requirements, all of which need to be optimized simultaneously. In this study, a validated mathematical model was used to perform the single - objective optimization of the FCC system at the design stage. In the optimization study, four operating parameters were used as decision variables. These variables were chosen based onsystematic sensitivity analysis of the system which showed complex interplay of the decision variables over the system performance indicators. Elitist Polymath version 5.1 enhanced with Excel flow sheet 2007 were used to solve a number of objective function optimization problems. The objective functions used are maximization of the gasoline yield, and minimization of the catalyst flow rate. The optimal results obtained here provide physical insights that can help in the design stage of the downer reactor.

Abstract: ان الهدف من هذا البحث هو تحضير دقائق السليكا النانوية من رمال السليكا العراقية من منجم ارضمة غرب العراق باستخدام طريقة الطحن المتعدد في (جهاز الطحن بالكرات)،حيث تم تشخيص دقائق السليكا بواسطة اجهزة التشخيص التالية SEM, AFM, PSA,FT - IR, XRD, XRF, BET,TEM. | The purposes of this work are to prepare, characterize silica nanoparticles for a first time from Ardma location at Anbar province in western Iraq by combination of top down approach using ultrafine grinding (Ball milling) and drying processes, evaluate the effect of nano - silica sand (NSS) addition on mechanical properties (compressive and splitting tensile strengths) of mortar mixture, and optimization of the operating variables (NS particle size and percentage of (NS) by using [WinQSB] and [STATISTICA] software technique to find the optimum values. (XRF) test shows enrichment of SiO2 after leaching with sulfuric acid. The prepared (NS) is characterized by SEM, AFM, PSA, FT - IR, XRD, XRF, BET and TEM. According to Particle Size Analyzers (PSA) silica sand has successfully been reduced to particle size of 50 nm after (30) hours of milling. The (AFM) test reveal two different groups of samples were analyzed, the range of first group was (60 - 120) nm after 40 hours of milling, the range of second group was (90 - 170)nm after 50 hours of milling. X - ray diffraction of silica sand before and after milling process shows that surface , structural changes duo to amorphization phenomenon result from an intensive mechanical treatment by (Ball milling) of silica sand. This result supports the incorporating (NS) into cement mortar. The (BET) analysis shows that the (NS) has different surface areas according to particle size. The (TEM) and (SEM) images of NS show that various shapes of the(NS) particles including irregular, spherical, and highly agglomerated in shape due to Van der Walls force on the particles surface. Three different ranges of particle sizes of (NS) have been used; (30 - 100)nm,(60 - 120)nm and(90 - 170)nm with three percentages of each (2% ,6% and 10% per weight of cement) and a w/c of 0.48. The SEM images of mortar mixture at the age of 28 days show existence of many Ca(OH)2 crystals needles over - shadowed and cover a large area with porous structure, while after adding (NSS) the Ca(OH)2needles are invisible and compact structure with the absence of the un - hydrated crystals which explains the superior strengths results. NSS contributes to enhancement of cement mortar through yielding denser, more compact and uniform mixtures. The optimization results of mechanical properties proved that an improvement in compressive strength of 29.889% at optimum conditions (adding 6% of 50nm particle size) in 28 days age, while for tensile strength was 22.863% at optimum conditions (adding 8% of 50nm particle size) in 28 days age. NSS obtained by ball milling of silica sand can be produced in large quantities at low prices, by sustainable method so that mass application in concrete is within reach According to my knowledge there is no previous work focusing on preparing of silica nanoparticles from Iraqi silica sand, and using it to improve mechanical properties of cement mortar by using optimization technique.

Abstract: ان النمو المضطرد في انتاج النفوط الثقيلة والطلب المتزايد على المقطرات الوسطيه اعطى اهمية قصوى لعمليات التكسير في المصافي النفطية، وتعتبر طريقة (H - Oil) باستخدام مفاعلات الطبقة الفوارة واحدة من اهم عمليات التكسير المحفز والتي تهدف الى تكسير النفوط الثقيل | The present work was devoted to study the hydrodynamic characteristics of a lab - scale cold - flow ebullated bed three phase column. It was also to investigate the kinetic behavior of an industrial - scale ebullated bed reactor, licensed by Axens Co., installed and operated in Lukoil refinery at Bourgas - Bulgaria.For the design of experiments in the lab - scale cold - flow column, factorial method was introduced to study the influence of the operating variables (i.e., gas and liquid superficial velocities and the liquid internal reflux ratio) on the objective functions (i.e., individual holdups and bubble characteristics).Pressure gradient method was used to estimate the individual holdups and bed porosity along the column, while photographic method was utilized to obtain images of the moving gas bubble which analyzed using Ai Adobe Illustrator CC (64 Bit) software to determine the geometric characteristics of bubbles.The results showed that liquid internal reflux ratio, which characterized the ebullated bed three phase bubble column, has a predominant effect on the individual holdups and bubble sizes.The operating and geometric variables of the lab - scale cold - flow ebullated bed were carefully selected to simulate the hydrodynamic characteristic of the industrial unit through matching five dimensionless groups (M - group, E?tv?s number, Reynolds number, density ratio and velocity ratio) of the cold - flowlab - scale and industrial systems.The percentage average deviations between each two particular groups of the two systems were (14.7%, 25%, 13.14%, 15.2%, and 20%), respectively. Although this did not result in a perfect match, considering the uncertainty in the industrial units exact operating properties, the match was considered to be sufficiently close.A five - lump kinetic model was selected, to describe the catalytic hydrocracking of heavy oil, to formulate the reaction rate equations of vacuum residue, vacuum gas oil, middle distillate, naphtha, and gases. These equations were inserted into the individual mass balance equation of each lump and then utilized in a program of MATLAB based on the nonlinear least square method to estimate the kinetic parameters (rate constants and activation energies of the proposed reaction pathways), to investigate the effect of the operating variables (e.g., operating temperature, WHSV, and reaction time ) on the kinetic parameters and performance of the industrial ebullated bed reactor. It was found that, - The intra - pellet (internal) diffusion was the rate - limiting step in the H - Oil reaction system. - The effectiveness factor decreases with increasing reaction temperature and WHSV. - The outcomes of the mathematical model confirmed the reaction orders of hydrocracking of vacuum residue and catalyst deactivation to be 2.1 and 0.18, respectively. - Activation and deactivation energies resulted to be quite similar of 48.87 and 50.68 kcal/mole, respectively, meaning that there is no strong effect of the deactivation process over the global hydrocracking reaction. - The hydrocracking of vacuum residue has a higher selectivity toward VGO production than toward other lumps in the following order : VGO < Middle Distillate < Naphtha <Gases. - WHSV has a negative impact on yield fractions of the industrial ebullated bed reactor while the images were different with the operating temperature. The formulated model was validated by comparing its outcomes with the findings of other related model (e.g Sa´nchez and Ancheyta, 2007) from literature. The results of comparison confirmed the reliability of the present model.Key words : Hydrodynamic, Kinetic Parameters, Heavy Oil, Ebullated Bed, Reactor.

Abstract: تناول البحث دراسة وتطبيق ظاهرة تقليل الاعاقة لاطالة مسافة تصريف السوائل الساقطة بشكل حر من انبوب افقي. حيث تمت دراسة تاثير ارتفاع ونوع السائل , نوع وتركيز البوليمر , قطر الانبوب وخشونة سطحه, واحدى المواد ذات الفعالية السطحية.تم اجراء الاختبارات العملية | Drag reduction phenomenon has been studied and applied to extend the discharge distance of kerosene, gas oil and tap water falling freely from horizontal tube. The effect of liquid head, type of solvent, polymer characteristics and concentration, pipe diameter and roughness and addition of surfactant were investigated.Experimental tests were performed using apparatus consisting of a reservoir connected to a horizontal tube from which the flux was allowed to fall freely under different heads. The distance traveled horizontally was measured and used to estimate the friction factor (ƒ) and the percentage drag reduction (%DR). The tests were carried out under liquid heads of 140, 165, 190, 215, 240 cm to ensure turbulent flow circumstances, i.e. Re ? 3000.Three types of polymers were tested, viz., polyisobutylene (PIB), xanthan gum (XG) and guar gum (GGM). The activities of these polymers for drag reduction were evaluated at concentrations of 10 - 200 ppm for PIB and 50 - 400 ppm for XG and GGM using three solvents, viz., kerosene, gas oil and tap water. Glass tubes of 3,7,10 and 11mm diameters in addition to carbon steel and stainless steel pipes of 10mm diameter were used to investigate the effect of pipe diameter and roughness.The interactions between polymer and surfactant were investigated using sodium luaryl sulfate (SLS) so that experimental tests were performed with PIB in the absence and presence of (SLS) at different concentrations. The discharge distance and %DR is generally increased with increasing liquid head and additive concentration. However %DR is sometimes reached to a maximum value at a specific concentration termed " critical concentration" beyond which %DR is fallen, the %DR observed with 100ppm of PIB is 44.3% at head equal 140 cm and 56% at head equal 240 cm from stainless steel tube. Moreover, %DR is progressively increased with increasing Reynolds number (Re) at any specific concentration, %DR achieved due to the addition 50ppm of PIB is 20.8% at Re equal 17236 and 45.9% at Re equal 26056 from stainless steel tube.Polyisobutylene has effectively reduced drag with kerosene and gas oil. Its activity seems to be higher with gas oil compared to that with kerosene. The maximum %DR achieved due to the addition 100 ppm of PIB in gas oil and kerosene are 63% & 56% respectively from Stainless steel tube. The activity of SLS for drag reduction with kerosene is evidently lower than that of PIB, and the difference between %DR observed is reduced with increasing concentration. Efficiency of PIB is considerably decreased by adding SLS so that the maximum %DR achieved with their mixture is 40.1%.The polymers XG and GGM are effectively reduced drag when added to tap water. Their activities at any specific operating conditions are decreased according to the sequence of XG ? GGM. The maximum %DR observed with them at 300 ppm are 77% and 48.8% respectively. The values of (%DR) measured with all tested liquids seem consistent with Blasius equation and they are progressively shifted to the direction of Virk asymptote with increasing of polymer concentration. The percent drag reduction is well correlated with Reynolds numbers, (L/D) and polymer concentration according to the relation of the form %DR= a (Re)b (C)d (L/D)k, where a, b, d and k are constants, so that a specific empirical correlation is observed for each polymer.

Abstract: وجودالكبريت في النفط الخام يشكل تحديات هائلة فيما يتعلق بالاثار البيئية والاقتصادية السلبية.وعلى هذا النحو ايضا سلامة المعدات معرضة لمخاطر عالية اثناء معالجة نفط خام الاحدب(3,55? كبريت) بسبب طبيعته الحامضية.وبالتالي فان هذا البحث يهدف الى تقليل محتوى الك | The presence of sulfur in crude oil posses enormous challenges as regards its negative environmental and economic impact. As such, the safety of the equipment is at high risk during the processing of Al - Ahdab crude oil because of its sour nature (3.55wt% sulfur). The present work is aimed at reduce the sulfur content of Al - Ahdab crude oil prior to processing by oxidative desulfurization treatment method using ultrasonic irradiation probe and high speed homogenizer for the enhancement of oxidizing the sulfur compounds and converting them into sulfones. The oxidation step was then followed by solvent extraction to extract the sulfones.An ultrasound - assisted oxidative desulfurization (UAOD) with hydrogen peroxide in the presence of acetic acid and subsequent solvent extraction using a polar solvent (acetonitrile ) has been applied for the desulfurization of Al - Ahdab crude oil in a bench scale unit. The results indicate that the desulfurization efficiency is dependent on the sonication rate. The measured sulfur content of the crude oil, obtained after 10 minutes contact time indicated that the highest efficiency obtained is 81.86%, corresponding to reductionin sulfur content up to 0.664wt.%, when sonication energy of 21139J was used. The second mixing scheme examined was that of using a high speed homogenizer. The results indicate that the desulfurization efficiency increases with increasing mixing speed from5000 to 26000rpm, and reaction time from 15 to 60min. The highest desulfurization efficiency obtained was 72.6% at 26000rpm and 60min reaction time. The above results indicate that UAOD is a successful process to upgrade Al - Ahdab crude oil. However, oxidative desulfurization assisted by high speed agitation also gave reasonable desulfurization efficiency. The sulfur content was reduced to about 1.2% which is less than that of Kirkuk crude (2.8%) and that of AL - Basrah crude (3.16%).

Abstract: تم تحضير ماده السليكا النانويه المسامية (SBA - 15) باستخدام (TEOS) كمصدر للسيليكا و(P123) كقوالب ومن ثم اجريت فحوصات عليها منها حيود الاشعة السينية (XRD),المجهر الالكتروني (SEM)،المساحة السطحيه ( (BET وطيف الاشعة تحت الحمراء (FTIR). بعد ذلك تم دراسة سلو | Santa Barbara Amorphous (SBA - 15) nanoporous silica was prepared using Tetraethylorthosilicate TEOS as silica precursor, Pluronic P123 as template, and characterized by means of X - ray diffraction (XRD), scanning electron microscopy (SEM), BET surface area and fourier transform infrared (FTIR) spectroscopy. The adsorption behavior of methylene blue from synthetic wastewater onto mesoporous SBA - 15 was studied. Both batch and continuous systems were studied. Batch experiments were carried out to measure the adsorption as a function of contact time, initial concentration (15 - 110 mg/l), pH (3 - 11) and adsorbent dose (0.1 - 2.3g/l) to specify the optimum operation condition. The equilibrium of the process was achieved within 20 min. Adsorption isotherms were fitted with the Langmuir, Freundlich and Temkin models. The equilibrium data were best represented by the Langmuir isotherm model with higher correlation coefficient R2 value of (0.990). The kinetics of the MB sorption on SBA - 15 were examined by using pseudo - first and pseudo - second order kinetics models. The kinetics analysis manifested that the overall adsorption process was successfully fitted with the pseudo - second - order kinetic model. In continuous studies, the adsorption of methylene blue from synthetic wastewater onto SBA - 15 in fixed bed was investigated and breakthrough data of the dye was determined. This research is run in small scale column with an internal diameter of 0.7 cm and 35 cm height at constant temperature and pH value. The effect of bed height (3, 6, 9 cm), flow rate (0.6, 1.0,1.4 ml/min) and initial MB concentrations (40, 70, 100 mg/l) on breakthrough curves were investigated. It is found that breakthrough time increases with increasing bed height, but decreases with increasing methylene blue inlet concentration and flow rate. Thomas and Yan models were used to determine the kinetic constants and to predict the breakthrough curves. The experimental data showed a better fit to Thomas adsorption model. In order to find out the possibility of reuse SBA - 15, desorption study was also carried out in this investigation. SBA - 15 can be effectively recovered by calcinations and reused fourteenth times in batch system and five times in continuous system without significant loss in removal of methylene blue from aqueous solution. The long reuse life of SBA - 15 makes it an efficient adsorbent for removal of methylene blue from wastewater at high potential for application in industry.

In addition, it is a core of any petrochemical complex. In such plant, the natural gas is subjected to many processes to separate the components. The objective of this study is to develop a detailed model to simulate an ethylene plant, which includes a pyrolysis section, a separation system and an integrated refrigeration system. An optimization has been performed for a part of the plant; this part is the furnace.The ethylene plant at the Petrochemical Complex in PC1 - Basrah has been considered as a case of study. The kinetics of ethane thermal cracking in pyrolysis furnace has been simulated using Aspen Plus and MATLAB. The radiant coils in furnace have been modeled as a one dimensional plug - flow reactor in which ethane is subjected to steam cracking. The overall plant has been simulated using Aspen Plus version (7.3), and the reactor has been simulated using MATLAB environment, version (2013a) in addition to Aspen Plus. The validity simulation model test has been achieved by comparing the simulation results with the actual data collected from PC1and it showed a great similarity and reliability for both simulation models.A steady state simulation model has been developed to study the behavior of multi - types feed supplied to the plant. Furthermore, the model has been used to evaluate the effects of various process parameters, including temperature of reaction (Reactor outlet temperature), dilution steam to ethane ratio (DS/HC) and the outlet flow rate of hydrocarbons.The other aim of this study is to obtain the optimum operating conditions using Aspen Plus for the reactor in the furnace which has an effect on the final product to determine the maximum profit.

Abstract: يتم انتاج كميات كبيره من الماء المصاحب النفطي من قبل شركة نفط الجنوب.يعتبر محتوى النفطي oil - water والاملاح الذائبه TDS من اخطر الملوثات والتي تتم معالجتها باحدث التكنلوجيا في السنوات الاخيره تم استخدام تقنية الاغشية لمعالجة الماء المصاحب النفطي.الهدف م | A large amount of oil field produced water is generated by South Oil Company. Oil - in - Water and TDS are the most serious pollutants for which current treatment technologies are often costly and ineffective in order to reuse water. In recent years, membrane process has been applied for produced water treatment.The aim of the present work is to treat produced water from oil well before being disposed in environment or reused as re - injection to oil well or agriculture water. Oil field produced water is very difficult wastewater to treat and its characteristics change as well to well. The sample test of this study was taken from dehydrator in the DSI/North Rumila/Southern Oil Company in Basrah /Iraq. The treatment process of produced water consists of two stages. The first stage as pre - treatment is achieved by continuous dissolved air flotation (DAF) to reduce the oil content. The second stages, as advanced treatment processes, are accomplished by microfiltration (MF) to reduce the turbidity and nanofiltration (NF) to reduce the salt content as TDS of produced water. The experimental work was carried out using dissolved flotation column is of Perspex glass (0.1 m I.D, 1.5 m height). The bottom of the column connected to a conical joint of QVF glass with a Teflon distributer. The effect of operating parameters (flow rate of produced water, pH, initial oil concentration, flotation time, alum dosage and surfactant of SLS) saturated pressure=5 Atm on the oil content or oil removal efficiency was investigated. The results showed that the oil removal efficiency increases with increasing the flow rate of produced water, the flotation time and coagulants dosage. The oil removal efficiency in DAF unit without coagulants is equal to (80, 94, 95%) for initial oil concentration (30, 50, 70 ppm), respectively at a flow rate 0.03 m3/h and pH=6. While flotation with coagulation, the results indicated that the removal efficiency is equal to 94% (residual oil content <10 ppm) at pH=5, alum dosage=560 ppm, and initial oil concentration=50 ppm, and the removal efficiency is equal to 89.6 at pH=6, alum+SLS dosage=80 ppm, and initial oil concentration=50 ppm. The kinetics of flotation column was studied and it was found that the order of the reaction is changing between zero to first order.The treatment of produced water by membrane technique was carried out by cross flow mode in hallow fiber microfiltration (MF) and nanofiltration (NF). The effect of operating parameter such as transmembrane pressure (TMP) (1, 1.5, 2 bars) with cross flow 20 mL/min, at room temperature, on the flux, rejection, and turbidity and TDS removal was studied. The experimental results by MF manifested that the permeation flux is (108, 156, 611 l/m2.h) and transemembrane pressure is 2 bar at initial turbidity (100, 200, 300 NTU), respectively. But NF, as a final treatment of produced water to reuse, was studied at different feed concentrations (82950, 75050, 67150 ppm) with different TMPS. According to the experimental results, the higher permeation of flux =15 (l/m2.h) at 82950 ppm and 2 bar, was obtained.The experimental results of the removal efficiency were represented in two and three dimensional graphs. An empirical correlation for R% as a function of different parameters (flow rate, pH, and oil concentration) was developed by aided computer using the following formula %R= a + c1*x1n1 + c2*x2n2 + c3*x3n3.

Abstract: يمكن اعتبار نظام المغلي التنوي واحدة من اكثر الطرق فعالية لزيادة التبادل الحراري في منطقة صغيرة نسبيا. انتقال الحرارة في الغليان الحوضي لموائع النانو تم التحقق عنها تجريبيا باستخدام مياه الالومينا AL2O3 ومياه ثاني اوكسيد التيتانيوم TiO2.كموائع نانويه (n | Nucleate boiling regime can be considered one of most effective ways to increase the heat exchange in a relatively small area. Pool boiling heat transfer nanofluid was investigated experimentally using Al2O3 - water and TiO2 - water nanofluids. The experimental test rig consists of boiling vessel and electrically heated plate heating element of stainless steel as heating element. Different concentrations of nanofluids were tested (0.05w %, 0.1w %, 0.3 w%, and 0.5 w %). The nanofluids for Al2O3 and TiO2 were prepared by mixing the( Al2O3 and TiO2) nanoparticles with distilled water in magnetic stirrer for three time periods at (2, 3 and 4) hours and for 1 hour in an ultrasonic bath to suspend the nanoparticles in base fluid. The nanofluids were scanned by scanning electron microscope to ensure well dispersion of nanoparticles in distilled water. Experiments were carried out firstly using pure water then nanofluid to compare the heat transfer enhancement. Results give maximum enhancement ratio in heat transfer rate of (100%) for 0.5% weight concentration for Al2O3 - water nanofluid and (81.82%) for TiO2 - water nanofluid at the same concentration. In both nanofluids the enhancement ratio increases with increased nanoparticle concentrations.This lead to increase in pool boiling heat transfer coefficient.

Abstract: Catalytic naphtha reforming is one of the key processes in petroleum refining, converting gasoline boiling range low - octane hydrocarbons to high - octane compounds which can be blended into gasoline. Other valuable by products include hydrogen and cracked light gases. Modeling of a typical semi - regenerative catalytic reformer of Duara refinery has been carried out involving most its key constituent units. Kinetic modeling of the reactions occurring in the fixed bed reactors connected in series formed the most significant part of the overall simulation effort. A reaction scheme involving (15 pseudo components) connected to gether by a network of 30 reactions for components in the C5 - C10 range has been modeled. The Hougen - Watson Langmuir - Hinshelwood type reaction rate expressions are used to represent rate of each reaction. Deactivation of the catalyst was modeled by including the corresponding equations for coking kinetics. It was found that Paraffines and Naphthenes undergo a continuous reduction through the three reactors while the rate of formation of aromatics is becoming slower as the reactants proceed to the third reactor. The reactor of naphtha reforming could be considered as a hydrogen production.

Abstract: Due to the dramatic environmental impact of sulfur emissions associated with the exhaust of engines, sulfur content specification for diesel fuels became more and more stringent worldwide. Last environmental regulations for ultralow sulfur diesel require very deep desulfurization processing, which cannot be met by the conventional hydrodesulfurization process (HDS).The present work focuses on benefiting from integrating an ultrasoundassisted oxidative desulfurization process (UAODS) with the conventional HDS process to produce ultra - low sulfur fuels. The proposed method involves a batch ultrasound - assisted oxidative desulfurization process to desulfurize a previously hydrotreated diesel containing 480 ppm sulfur. The oxidizing system used was H2O2/CH3COOH with FeSO4 being used as a catalyst. An ultrasonic probe system was used to enhance the conversion of sulfur - bearing compounds that exist in diesel to sulfones and sulfoxides to affect their removal by a certain separation method, such as extraction or adsorption.The major influential parameters related to UAODS process have been investigated, namely : ratio of oxidant/fuel, ratio of the promoter/oxidant, dose of catalyst, reaction temperature, intensity of ultrasonic waves. A set of comparative studies were also carried out including type of extraction solvent, effect of initial sulfur content, and type of sulfur separation method. Total evaluation for the treated diesel was performed, including GC - MS analysis which has been used to monitor the change of organic sulfur compounds andhydrocarbons in diesel during the desulfurization process.The oxidation treatment, in combination with ultrasonic irradiation, revealed a synergistic effect for diesel desulfurization. The experimental results showed that the removal efficiency for sulfur compounds could amount to 98%, and sulfur level can be reduced to 12 ppm at mild operating conditions (70 and 1 bar). This indicates that this process is so efficient and promising for the production of ultra - low sulfur diesel fuels.The kinetics of the reaction has been also studied. It was observed that the UAODS of diesel fuels fitted pseudo - first - order kinetics under the studied experimental conditions. During this process, values of the apparent rate constant and activation energy were 0.373 min - 1 and 24 kJ/mol, respectively.

The galvanic corrosion cells for all couples have equal areas of anode and cathode (2×2cm).The galvanic current density (ig) is increased with increasing solution concentration and temperature. The galvanic potential (Eg) is shifted to less negative with increasing solution concentration and temperature and it is close to the corrosion potential of the anode in the couple conditions.The potentiostatic polarization behavior of single three metals (Copper, Carbon Steel and Zinc) in different concentrations of dilute HCl acid (0.025, 0.05 and 0.075M) at temperature (40°C) is found under activation control. The corrosion current density is increases with increasing solution concentration and gives the following arrangement of metals : Cu> Fe > Zn A numerical analysis of galvanic corrosion was presented. The analysis was based on three numerical methods as the boundary element method (BEM), the finite element method (FEM) and the finite difference method (FDM).The potential and current density distributions on the galvanic elements are described by the Laplace equation. The Laplace equation was solved numerically, to determine the potential, current density, and corrosion caused by the galvanic cell using designed computer programs in MATLAB R2014a. The experimentally determined polarization curves have been used in order to define the nonlinear boundary conditions. This boundary value problem has been solved using Newton - Raphson iterative numerical procedure. For the three couple systems (Cu - Fe, Fe - Zn and Cu - Zn), the results obtained for galvanic potential and current density, using the numerical methods (BEM, FEM and FDM) with the overall deviations are 6.689, 10.818 and 18.846 respectively for galvanic current density and 0.631, 1.210 and 1.787 respectively for galvanic potential. From these results it can conclude that the galvanic current density and galvanic potential distribution calculated from the BEM model was in good agreement with the experimental measurements. These are because the main advantages of the BEM over the Finite Element Method (FEM) and the finite difference method (FDM) are high accuracy, discretization on the boundary only which results in a very small number of unknowns, easy dealing with non - regular boundaries and openings that only the domain boundary of interest is required to be discrete, also BEM needs fewer equations and a smaller matrix size than FEM and can solve both finite and infinite domain problems.

So disc samples of (7075, 6061 and 5083) aluminum alloys of 2 mm thickness and 25 mm diameter, have been prepared. Polarization tests were carried out in (M lab potentiostat / galvanostat) (Germany) at 298K temperature and (1.5, 2.5 and 3.5) % wt of NaCl solution. The experiments were carried out before and after laser surface melting by (Nd : YAG, MED - 810) pulse laser, system (Q - Switched Nd : YAG 1064/532nm). Before laser surface melting the results showed that the value of the corrosion current density obviously increases with increasing the concentration of NaCl from 1.5% to 3.5%. As well as higher Cl - ions concentration more negative pitting potential (Epit) of aluminum alloys and decrease in the electrochemical stability of aluminum. The corrosion rate for the specimen 7075 is larger than that of 6061 and 5083 aluminum alloys under the same conditions. So it means that the specimens 6061 and 5083 have high resistance to corrosion in NaCl solution After laser surface melting the results showed that the surface of aluminum alloys became more homogenous and pure after treatment.It was found that the corrosion current density decreases after Laser Surface melting at about three orders than that of untreated samples, therefore, the value of the corrosion rate of laser - treated alloy is smaller than that of the untreated. As well as the pitting corrosion potential after Laser Surface melting obviously shifted to more positive direction for all aluminum alloys in different concentrations of the NaCl solution.

A theoretical model for the plate heat exchanger was developed based on the heat balance. A step change is carried in the hot water flow which is considered as a manipulated variable.The results of plate heat exchanger (PHE) showed that the dynamic behavior of plate heat exchanger in this work is dynamically as a first order lead and second order overdamped lag with a significant delay time as shown below : G(p)=(T ?_co (s))/(m ?_h (s) )= ((0.2645s+1.411) e^( - 5.63s))/(0.2156s^2+12.34s+1) The experimental heat transfer measurements of the plate heat exchanger (PHE) indicated that the overall heat transfer coefficient (U) is related to the water flow rate (m) by a correlation having the form : U = 10637 m0.7307 To verify the presented model, temperature control was applied theoretically and experimentally to the plate heat exchanger using conventional P, PI and PID controllers with tuning of control parameters by different methods; Ziegler - Nichols, Cohen - Coon and genetic algorithm to find the best values of proportional gain (Kc), integral time (?I) and derivative time (?D). The time domain specifications like rise time, settling time, overshoot and the performance indices, Integral Squared Error (ISE) and Integrated Time - Weighted Absolute Error (ITAE) were used to evaluate the performance of different control strategies. The PID controller gave better control results of temperature than other controllers, while Ziegler - Nichols tuning method gave better control results than Cohen - Coon. GA technique is the best method in simulation by compare with Cohen - Coon and Ziegler - Nichols methods. Therefore, GA method is suitable as best technique for systems which have shorter constant time.Cohen - Coon and Ziegler - Nichols methods were used in the experimental work to calculate the controller parameters, while GA method was not used in this stage.
