Abstract: في العراق معدل تراكيز الزيوت والشحوم (OG) في الماء المنتج يجب الا يتجاوز 09 ملغم\لتر. ولذلك فانه يتطلب معالجة المياه المنتجة بغية تلبية الحد التنظيمي للتصريف مسبقا.تم جلب نماذج الماء المنتج الخام من شركة نفط الوسط ) Md.O.C ( من الحقول النفطية من شرق بغد | In Iraq the average Oil and Grease (OG) in water concentration in discharge produced water must not exceed 10ppm. Therefore treatment of produced water is required in order to meet the pre - disposal regulatory limit.Raw produced water samples were procured from the Middle oil company (Md.O.C) (from East of Baghdad fields).Jar tests experiments were used to give a first, rough estimation for coagulants dosage of Ferric chloride and aluminum sulfate and pH values that will be used in the batch Dissolved Air Flotation (DAF) experiments. Then, the effects of the three ionic liquids (ILs) types; 1 - hexyl - 3 - methylimidazolium tetra fluoroborate (ILE), 1 - hexyl - 3 - metylimidazolium hexafluorophosphate (ILF) and 1 - octyl - 3 - methylimidazolium tetra fluoroborate (ILG) on the performance of the batch DAF unit were evaluated.It was concluded that, the beast operating conditions of the batch DAF unit were at a saturation pressure of 5 bar, recycle ratio of 50% and ambient temperature of 30 - 35 ?C. Ferric chloride with a dosage of 10 ppm was chosen as the suitable coagulant due to its low sensitivity to pH change, and its high removal efficiency for oil and turbidity in about ten minutes. ILs were used at concentration of 50 ?l per one liter of treated produced water. It was used in two positions of the DAF system; the saturation vessel and the treatment tank. The OG removal efficiency using ILG as an efficient surfactant in saturation vessel was higher than that in the treatment tank and higher than other ILs (ILG>ILF>ILE). The highest demulsification rates were obtained through saturation pressure range (2 - 5) bar. It reached about 90% removal efficiency at a pressure of 5 bar, and it was obtained 85% at saturation pressure of 3 bar which reduces the operation costs. The treated water concentration at 3bar was 9.5 ppm which meets the Iraqi pre - disposal regulatory limit.The results of testing the three ILs (ILE, ILF and ILG) in the saturation vessel and the treatment tank were used to produce contour line for the OG removal efficiency. This was conducted in order to detect the performance of the three ILs The results of optical microscope which was used to study coalescence of oil droplets in water phase, lead to consider the ILG as an effective demulsifier for Iraqi oil field produced water It was noted that the use of ILs in saturation vessel allowed micro bubble generation at operating pressures lower than 3 bar with high - energy savings.

Abstract: ان تاكل الهياكل المعدنية المدفونة في التربة والتي على اتصال مع التربة لفترة طويلة تعتبر مشكلة هندسية واقتصادية كبيرة.في جميع انحاء العالم هنالك الكثير من انابيب النفط والغاز والماء وكابلات الاتصالات وكذلك صهاريج التخزين والمباني والاسسات والعديد من الهيا | The corrosion of metallic structures buried in soils or in contact with soils has long been a serious engineering and economic problem. All over the world millions of kilometers of gas, water, oil pipelines, communication cables, power cables as well as storage tanks, buildings foundations, and many other structures are buried in the soil, suffering from soil corrosion problems which affect mainly the external surfaces of these structures. In many countries pipelines are by far the most important means of hydrocarbon transportation. This applies to the transport of crude, finished products and natural gas.It is an international problem with more structures and materials buried in the soil. The truly international scope of interest of this subject can be seen by the amount of literature and researches in this field. Attempts have been made to overcome this problem by the use of various types of techniques. The most common and applicable technique is cathodic protection.In this research a carbon steel pipe of length 100 cm buried in a wooden box submerged by soil and impressed current cathodic protection system (ICCP).was applied using power supply and electrical closed circuit, several important factors affecting the pipe protection from corrosion has been studied, like Anode position (distance and depth), soil resistivity (wet and dry), condition the pipe (coated and un - coated), distribution of potential and currents along the pipe(cathode) and the amount of current required to achieve cathodic protection.A correlation was achieved to simulate the ranges of parameters and factors affecting Impressed Current Cathodic Protection. Regression of this model to data and results yielded parameter values vary depending on the effect of the same factor.

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.

Abstract: في هذه الدراسة, تم بحث مدى ملائمة عمليات التنافذ (الامامي - العكسي) لمعالجة المياه الملوثة بالزيوت. حيث طبقت عملية التنافذ الامامي لاسترجاع الماء النقي من المياه الملوثة بالزيوت. تم استخدام زيت محرك الديزل والكازولين نوع (15W - 40) لتحضير محلول اللقيم, بي | In this study, the feasibility of Forward - Reverse membrane osmosis system was investigated for treating the oily wastewater. Forward osmosis (FO) process was applied to recover pure water from oily wastewater. Gasoline and diesel engine oil (15W - 40) was used to prepare the feed solution (FS). While sodium chloride (NaCl) and magnesium chloride (MgCl2) salts were used as draw solutions, and the membrane that was used in FO process was cellulose triacetate (CTA) membrane. While reverse osmosis process was used to recovery water from the diluted draw solution using polyamide (thin film composite (TFC)) membrane. In the first stage was applying the FO process for treating the oily wastewater with two parts. The first part included the FO process using the batch system whereas the second part included the FO process using the flowing system for different draw solutions. Theoperating parameters studied were : draw solution type, draw solution concentrations (0.25 - 0.75 M), oil concentration in FS (100 - 1000 ppm), the temperatures of FS and DS (30 - 45 °C), pH of FS (4 - 10) and for the forward osmosis flowing process the flow rate of both DS and FS (20 - 60 l/h), while the pressure was maintained at 0.5 bar. The run - time of the FO process was for five hours. It was found that water flux through membrane decreases with increasing time, while oil concentration in the FS increases with increasing time. Also, it was found that the water flux produced from the osmosis cell and oil concentration in FS increase by increasing the concentration of draw solutions, the flow rate of FS and the temperature for a limit (40oC), then, the water flux and oil concentration decrease with increasing the temperature because of happening the internal concentration polarization phenomenon. By increasing the oil concentration in FS and the flow rate of the DS, the water flux and oil concentration in FS were decreased. While it had a fluctuated behavior with increasing the pH of oily wastewater. It was found also that MgCl2 gives water flux higher than NaCl. It was observed that the best operating conditions in this study were : concentration of salt (0.75 M) for MgCl2, oil concentration (100 ppm), pH of FS (7.3), temperature of feed and draw solution (40oC), flow rate of FS (60 l/h), and flow rate of DS (20 l/h). The values of resistance to solute diffusion within the membrane porous support layer were 55.93 h/m and 26.21 h/m for NaCl and MgCl2 respectively. The second stage was applied reverse osmosis process for separating the fresh water from a diluted (NaCl) solution using different parameters such as draw solution concentration (0.08 - 0.16 M), feed flow rate (20 - 40 l/h) within two hours of work of the reverse osmosis system.

Abstract: ان التاكل الداخلي في انابيب الصلب الكربوني الذي يحدث بوجود غاز ثاني اوكسيد الكربون يعتبر مشكلة جوهرية في صناعات النفط والغاز وهو يقترن دائما مع وجود الماء. ان احتمالية حدوث التاكل تزداد بصورة عامة مع تزايد نسبة الماء ومع زيادة مستوى الماء المنتج تزداد مع | Internal corrosion of carbon steel pipelines occurring in the presence of CO2 is a substantial problem in the oil and gas industries. It is always associated with the presence of free water. The likelihood of corrosion generally increases with the volume fraction of the water phase. As the produced water level increases, the corrosion rates of carbon steel increase very rapidly and causes damage of petroleum and gas pipelines. The present research work focuses on the investigating of the corrosion rate of carbon steel as flow line in crude oil production with CO2 content employing three Iraqi crude oil (Kirkuk crude oil, Halfaya crude oil, Rumalia crude oil) with different brine concentrations [1%NaCl, 2%NaCl, 3%NaCl]. Determining the corrosivity of Iraqi crude oil was studied for the first time. Experiments were performed in an autoclave test apparatus, crude oil - produced water mixtures, water cuts were (0, 10, 20, 30, 40, and 100%), and total volume of mixtures inside the autoclave was always kept at 100ml and temperature (20, 40, 60°C). For all experiments, CO2 partial pressure was maintained at (4 bar) and rotational speed (500 rpm).The corrosion rates were determined by the weight loss technique. The results revealed that the corrosion rates of carbon steel increased by increasing water cut and temperature, but decreases with increasing salt concentration for all types of crude oil. Results also indicated that different crude oil has significantly different effects on corrosion of carbon steel, with identical brine compositions. Therefore, Rumaila crude oil exhibits the highest corrosion rates and Kirkuk crude oil exhibits the lowest corrosion rates while Halfaya crude oil exhibits a moderate corrosion rates e.g. at 1% NaCl, 20% water cut, temperature 60°C, pressure 4bar, the corrosion rate of carbon steel in Rumaila crude oil is 0.9163mm/yr whereas it is 0.564 mm/yr and 0.705 mm/yr in Kirkuk crude oil and Halfaya crude oil respectively. The Corrosion Rate Break produced water level was determined from the experiments. These tests are employed to evaluate the requirements for corrosion inhibitor treatment. At 100% water cut (brine/CO2) the corrosion rates of carbon steel was the highest. The presence of crude oil decreases the corrosion rates e.g. at 1% NaCl,100% water cut(brine/CO2) the corrosion rate is 7.1197 mm/yr, whereas at 40% water cut/ Rumaila crude oil the corrosion rate is 1.4097 mm/yr.

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. Optimization using Genetic Algorithm (GA) by MATLAB has been used as well as Aspen Plus, and a comparison has been made between both methods. The selection of the optimum operating conditions of reactor was obtained to achieve the following objectives together : • Increasing the production rate of ethylene.• Increasing the outlet flow rate of hydrocarbons.These objectives have managed to be achieved all together by maximizing the total profit obtained from the furnace. Finally, Aspen Plus results show that the objectives have been satisfied by manipulating the decision variables Temperature of reaction (Reactor outlet temperature) in the range of (850 - 920) ?C, dilution steam to ethane ratio DS/HC in the range of (0.2 - 0.5) and the outlet flow rate of hydrocarbons ) in the range of (2421 - 1064) Kmole/hr to increase the profit of the furnace to approximately (10.541%) and (5.55%) for the whole plant.

Abstract: الهدف الاساسي من هذا البحث هو تطوير طريقة عملية لمعالجة المياه المنتجة من حقول النفط العراقية. في هذه الدراسة تم توظيف نظام متحد من ثلاث عمليات معالجة هي التخثير والامتزاز والتبادل الايوني لازالة وتقليل بعض الملوثات الرئيسية مثل العكورة والمحتوى الزيتي وم | The overall goal of this research was to develop a practical method of treating co - produced waters from oil - field sources. In this study, combined coagulation - adsorption - ion exchange treatment was employed for the removal of some main contaminants like turbidity, oil content, and total dissolved solids from produced water. These combination steps are not studied before. The wastewater used in this work was taken freshly form Al - Ahdab oilfields. The coagulants used in this study were aluminum sulfate (alum) as a primary coagulant and calcium hydroxide (lime) as a coagulant aid. The performance of these coagulants was investigated through jar test by comparing turbidity removal at different coagulant / coagulants aid ratio, coagulant dose, water pH, and sedimentation time. The best conditions for turbidity removal can be obtained at coagulant dosage of 80 mg/L at pH 6 and 120 min for sedimentation time. There was an improvement in the turbidity removal when 25% lime was used in conjunction with 75% alum. At these conditions, the turbidity reading was reduced from 92 to 2.1 NTU. In addition, an attempt was made to examine the relationship between turbidity (NTU) and total suspended solids (mg/L) on the same samples of produced water. This study presents an investigation on the technical feasibility of using organoclay for adsorption of oil content from produced water. The organoclay was prepared by combination of Iraqi bentonite with quaternary amine (tetraethylammonium chloride). Batch mode experiments were conducted to study the effects of amine/ bentonite ratio, organoclay quantity, pH, and contact time. The analysis results showed that the organoclay adsorbent was very effective in removing oil content from produced water and the best results obtained for the removal of oil content are 16 g/L of prepared organoclay having 35 g amine/ 100 g bentonite, pH 3, and 120 min for contact time. These results reduce the concentration of oil content from 532.1 to 2.7 mg/L. Equilibrium adsorption isotherms and kinetics were investigated. The adsorption isotherm data were fitted well to Temkin isotherm as highest coefficient of correlation (R2=0.996) and lowest value of standard deviation (Sd=2.385). The adsorption kinetic data were fitted very well the pseudo - second order kinetics model (R2=0.997 and Sd=1.644). The continuous experiments were carried out in a fixed - bed column. The results revealed that adsorption capacity increases with increasing bed depth and with decreasing flow rate. In this work, a continuous ion exchange study in fixed - bed columns was performed to reduce TDS concentration from produced water. The experiments were subjected to lab - scale ion exchangers, consisting of two types of commercial resins connected in series. The two types of resins used in this work were : strongly acidic cation exchanger of type Dowex 650C and strongly basic anion exchanger of type Dowex I. 550A. Comparison of Thomas, Yoon - Nelson, and Adams - Bohart models with experimental kinetics results was done, and model parameters were evaluated by linear regression analysis for TDS reduction in different bed depths and flow rates. The obtained experimental data were in good agreement with Thomas and Yoon - Nelson models (R2 reaches to 0.996). Reverse flow regeneration was carried out in a fixed - bed column for exhausted resin by washing with diluted acid and base solutions. The regenerated resin was reused in the same column. Approximately, 65% of the original sorption capacity was restored.

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.

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.

Abstract: The present work deals with the improvement of Iraqi gas oil containing 1.402 wt. % sulfur by hydrotreating process using different prepared hydrodesulfurization catalysts (Ni - Mo/? - Al2O3, Co - Mo/? - Al2O3, Co - Ni - Mo/? - Al2O3, Ti - Ni - Mo/? - Al2O3 and Re - Ni - Mo/? - Al2O3). All catalysts were prepared under vacuum impregnation to ensure efficient precipitation of metals within the carrier ? - Al2O3. Physical adsorption by nitrogen was investigated, and used for determination of the surface area and pore size distribution of prepared catalysts.The results showed that modified catalysts Ti - Ni - Mo/? - Al2O3 and Re - Ni - Mo/? - Al2O3 have a high surface area 225.1 and 235.23 m2/g respectively, as compered with conventional prepared catalysts Ni - Mo/? - Al2O3 and Co - Mo/? - Al2O3 which their have surface area 178.5 and 191.4 m2/g respectively, and exhibits behavior of type four according to Brunauer, Emmett and Teller (BET) classification, and type H1 according to de Boer classification for hysteresis loop, so, it was concluded that the pores of these catalysts are cylindrical. The performances of all the synthesized catalysts for removal of sulfur and aromatic saturation gas oil were tested at different LHSV (1 to 4 h - 1), temperatures ( 275 to 350 °C), constant pressure 40 bar, and H2/HC ratio 500 ml/ml. The results showed that the sulfur and aromatic content were decresed at all operating conditions for all prepared catalysts. It was found that the sulfur removal from gas oil increases with temperature and decreasing with the space velocity, and the temperature has higher effect on the process of sulfur removal than the space velocity. It was found also that Ni - Mo/? - Al2O3 catalyst is slightly better in sulfur removal (61.5 wt. % ) with than Co - Mo/? - Al2O3 (59.2 wt. %) at the same operation conditions (350 °C and LHSV 1 h - 1), and hydrodesulfurization over Ni - Mo/Al2O3 was improved remarkly by adding Ti and Re promoters. Maximam sulfur removal was 76.81 wt. % using Re - Ni - Mo/? - Al2O3 at temperature 350?C, LHSV 1 h - 1, while minumum aromatic content value is 15.44 wt. % for Ni - Mo/ ? - Al2O3. Calculations showed that the hydrodesulfurization rate expressions fitted with second order reaction kinetics model.The rate constant varied from 0.005 to 0.144 liter/kg.h and the values of activation energy varied from 50.0 to 93.59 kJ/mole for all prepared catalysts. Thiele modulus, for all prepared catalysts was calculated.The lower values of the Thiele modulus (> 0.4) gives strong evidence of negligible pore diffusion limitation.

Hydrodesulfurization (HDS) removes sulfur compounds, such as mercaptans and sulfides from hydrocarbons; however, some sulfur - containing compounds (such as diebenzothiophene) are very difficult to remove and need deep desulfurization processes.This work was applied to the desulfurized diesel fuel produced from the conventional HDS process for ultra - desulfurization. The used fuel types in this investigation were either real diesel fuel or simulated diesel fuel, where sulfur - containing compound ( dibenzothiophene DBT) converted to its corresponding sulfone by oxidation using hydrogen peroxide as an oxidant and acetic acid as homogenous catalyst, and solvent extraction by using acetonitrile (ACN) or N - methyl - 2 - pyrrolidone (NMP) as extractants.Simulated diesel fuel according to British Petroleum 200B doped with dibenzothiophene (DBT) was prepared, the effect of stirring speed (150, 250, 350 and 450) rpm, temperature (30, 40, 45 and 50) ?C, oxidant/simulated diesel fuel ratio (0.5, 0.75,1 and 1.5) (v/v), catalyst/oxidant ratio (0.125, 0.25, 0.5 and 0.75) (v/v), solvent type, and solvent/simulated diesel fuel ratio (0.5, 0.6, 0.75 and 1) (v/v) were examined in order to obtain the maximum sulfur removal. The results of this work exhibit that the highest removal of sulfur 98.5% for N - methyl - 2 - pyrrolidone and 95.8% for acetonitrile were obtained under the conditions of operating in table below : Stirring Speed (rpm) 350 Temperature (?C) 50 Oxidant (hydrogen peroxide)/simulated diesel fuel ratio 1 Catalyst (acetic acid)/oxidant ratio 0.5 Solvent (ACN or NMP)/simulated diesel fuel ratio 1 Experiments with the above best conditions were carried out on Real diesel fuel obtained from Al - Dora refinery with 1000 ppm sulfur containing compounds. It was found that sulfur removal from real diesel fuel was 62.5% for acetonitrile and 75% for N - methyl - 2 - pyrrolidone.

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.

Extraction of essential oil is one of the most time and effort consuming process. Microwave - assisted extraction is a green technique for the extraction of natural products. (MASD) was better than (SD) in terms of rapidity, energy saving and yield. (MASD) gave higher yield than (SD) with shorter extraction time, yield of orange oil extracted by (MASD) was (1.150%) in (35min.) compared to (1.095%) in (45min.) by (SD) process, same results obtained for lemon and mandarin. It was found that the optimal microwave power was (135W) and the yield was : (1.150%, 1.115%, 0.940%) for orange, lemon and mandarin respectively, (MASD) increased extraction temperature in short time and to a higher level compared to (SD).It was found that the optimal weight was (398.56g) and the yield in (SD) was : (1.095%) and MASD (1.091%) for orange oil, same results obtained for lemon and mandarin.The best citrus peel type which gave the highest yield was orange followed by lemon then mandarin in both processes.Limonene is the most abundant component in citrus essential oil, (GC) analysis showed that the amount of limonene increased in low microwave power with long extraction time for mandarin oil it was (84.3891% at 135W in 60min.), while for (SD) it was (83.0271% in 75min.) and decreased with increasing microwave power for orange oil it was (80.9661% at 265W in 35min.) while for (SD) it was (83.2189% in 45min.), (SD) was more convenient to give high amount of limonene because of the graduate temperature rise, while in microwave extraction exposure to low microwave power for long time would give complete recovery and better quality of essential oil.

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.

Abstract: The inhibitive power of Polyvinyl Alcohol (PVA) and the synergistic effects added on the inhibition power of PVA by two types of Piper Longum (PL) Ethanol Extracts (PLEXT) were investigated toward the corrosion of carbon steel in (0.2N) H2SO4 solution in the temperature range (30 - 60?C) and PVA concentration range (150 - 2000 PPM).The corrosion rate measurements were carried out using the following two standard corrosion measurements techniques.1. Weight loss technique was applied on carbon steel plates to evaluate inhibition efficiency in presence and absence of these inhibitors.2. Electrochemical Techniques were used to validate and support inhibition efficiencies found in weight loss techniques.A detailed study of the experimental methods and results is reported for each test conducted.The weight loss results showed that PVA could serve as a corrosion inhibitor but its inhibition power was found to be low for the corrosion of carbon steel in the acidic media.It was shown that the inhibition efficiency for (PVA) decreased with increasing temperature at a given PVA concentration. On the other hand it was shown that at given temperature the inhibition efficiency of (PVA) was increased with increasing of PVA concentration until a PVA concentration of 2000 ppm PVA was reached then only a slight decrease in inhibition efficiency was observed when increasing PVA concentration further.The Maximum inhibition efficiency reached was about 71 % at 30?C & 2000 ppm (PVA) concentration, calculated by the weight loss techniques.In order to improve the inhibition efficiency of PVA, by adding 6 ml/l of ethanol extracts of piper longum (PL) to a liter of the acid solution in presence of concentrations of PVA 150,500,1000.1500, and 2000 ppm at temperatures (30,40,50, and 60?C) was investigated.Weight loss results showed a jump in inhibition efficiency (% IE) value of the modified inhibitor mixture compared with the presence of PVA alone at all (PVA) concentrations for temperature range considered in this investigation.This study demonstrated the extra inhibition power added by the (PL) fruit extracts to the organic polymer (PVA) used. Maximum inhibition efficiencies recorded were approximately 95% for Piper Longum Extract Number two (PLEXT2) at 30?C and 2000 ppm PVA.The kinetic and thermodynamic parameters regarding the adsorption process of inhibitors used was calculated.It was found that the changes corrosion rates correlates well with the Arrhenius equation in absence and presence of inhibitors.The Results showed that the adsorption of the polymer and the plant extract follows Langmuir adsorption isotherms and the adsorption of the inhibitor molecules on the metal surface is mainly physical, nevertheless the adsorption is believed to be slightly deviated from the Langmuir model at 30?C.Electrochemical analysis of the corrosion process of carbon steel in an electrochemical corrosion cell was investigated using 3 - Electrode corrosion cell coupled with a potentiostat interfaced with a computer which assisted polarization data interception and interpretation.Polarization technique was used to obtain polarization data which was recorded for carbon steel in 0.2N H2SO4 solutions in presence and absence of the inhibitors investigated. Electrochemical runs were done in the (PVA) concentrations of 150, 1000, and 2000 PPM and a temperatures of 30, 40, 50, and 60?C.Tafel slopes, Corrosion currents, and corrosion rates were calculated from polarization curves by Tafel extrapolation method. Results showed corrosion rate trends similar to findings by the weight loss method. It was indicated also that the corrosion of carbon steel in 0.2N H2SO4 is highly activity controlled.Results revealed that the inhibition action is occurring at both anodic and cathodic sites on the metal surface so that both corrosion reactions were affected, so that the composite inhibitor could be considered as mixed - type inhibitor.Electrochemical results confirmed that (PLEXT2) was more efficient as inhibition improvement additive to (PVA) than (PLEXT1) at all experimental conditions range encountered in this study.The highest inhibition efficiency recorded using Tafel polarization method was 83% obtained at 30?C and 2000 ppm of PVA with 6 ml/l PLEXT2.

Abstract: Present study deals with the preparation of activated carbon (AC) from date stones by K2CO3 activation via microwave heating and the removal of methylene blue (MB) dye from aqueous solution by using such carbon as adsorbent. The influence of radiation time (4 - 12min), radiation power (540 - 700W) and impregnation ratio (0.5 - 2.5g/g) on the yield and MB uptake of such carbons were studied. Central composite design was used to determine the optimum preparation conditions and two quadratic models were developed to correlate the preparation variables for both responses.The optimum preparation conditions were reported as 8 min radiation time, 660 W radiation power and 1.5 g/g impregnation ratio resulting in 19.99% yield and 460.123 mg/g MB uptake. From the analysis of variance (ANOVA), it was found that the radiation time had the greatest effect on the yield while impregnation ratio had the greatest effect on MB uptake.The characteristics of AC were examined by pore structure analysis, scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FTIR). The BET surface area and total pore volume were indentified to be 1144.25 m²/g and 0.656 m³/g, respectively. Batch adsorption study was adopted to determine the experimental adsorption isotherm data of different initial concentration of MB (50 - 450 mg/l). The equilibrium data were analyzed using Langmuir, Freundlich and Sips isotherm models. The results showed that the experimental data were well fitted with sips isotherm with maximum monolayer adsorption capacity of 484.7 mg/g. Pseudo - First order, Pseudo - Second order, and intraparticle diffusion models were used to analyze experimental kinetics data with high correlation coefficient for Pseudo - second - order model.

Abstract: تم دراسة انتقال الكتلة الخاص بايونات الكادميوم الثنائية الى سطح اسطوانة دوراة مصنوعة من مادة الفولاذ المقاوم للتاكل (كقطب كاثود) بواسطة قياس التيار المحدد لتفاعل اختزال ايونات الكادميوم الكاثودي في محلول كبريتات الصوديوم بتركيز مولار باستخدام خلية ثلاثية | 1 - Mass transfer of Cd+2 ions to a smooth stainless steel rotating cylinder electrode was studied by measuring the limiting current for the cathodic reduction of Cd+2 in 0.5 M sodium sulphate supporting electrolyte by three electrodes cell with stainless steel rotating cylinder electrode working in hydrodynamic voltammetry mode. The studied parameters were electrolyte pH (4, 5, 6 and 7), initial Cd+2 concentrations (50, 100, 200, 300 and 400 ppm) and rotation rates (100, 150, 200 and 250 rpm). Cadmium ions' reduction potential for mass transfer control conditions was found to be - 0.13 V. Diffusion coefficient was determined and correlated with the bulk concentration of Cd+2 in sodium sulphate solution. The increase in pH was found to enhance the mass transfer coefficient and this effect diminishes nearly at pH=7, and the experimental data were well fitted by an empirical dimensionless correlation among the Sherwood number, Reynolds number and Schmidt number. The obtained correlation was : Sh=0.047 ?Re?^0.769 ?Sc?^0.356 For (8015.519 < Re < 20587.07) Reduction potential obtained via the voltammograms constructed by the rotating cylinder cell was applied for the two pilot scale units in order to keep the process under mass transfer control conditions. Parameters studied in these units are : initial cadmium concentration, pH, and electrolyte flow rate. The first pilot scale unit was an electrochemical reactor with smooth stainless steel concentric tubes, and the second one was an electrochemical reactor with stainless steel mesh concentric cylinders.2 - For the stainless steel smooth concentric tubes cathode, mass transfer coefficient was calculated and correlated with initial concentration.Effect of pH on mass transfer coefficient was studied and correlated, and it was found that the effect of pH was found to be completely negligible at pH=7.On the other hand, effect of flow rate on mass transfer coefficient was studied and correlated. Performance of the reactor was analyzed by introducing figures of merit for fractional conversion, specific energy consumption, space time yield and normalizes space velocity. The experimental data were correlated in a dimensionless expression as flows : Sh=0.804?Re?^0.632 ?Sc?^(1/3) For 254 < Re < 1018.3 - For the stainless steel mesh concentric cylinders was adjusted to work under mass transfer control conditions by applying the reduction potential obtained in hydrodynamic voltammetry experiments.Effect of initial cadmium concentration, pH and solution flow rate was studied and analyzed. Mass transfer coefficient was correlated with these studied parameters.Similar to smooth cathode, the mesh cathode showed a negligible response to pH at pH=7.Noticeable enhancement in mass transfer coefficient was investigated by the action of flow rate, and the mass transfer coefficient was correlated with the solution flow rate.The mesh cathode showed a higher conversion than that adopted by the smooth cathode, and showed lower cumulative current efficiency than that of smooth cathode.Mesh cathode showed specific energy consumption, space time yield and normalized space velocity higher than that for the smooth cathode.Experimental data for the mesh reactor were correlated in a dimensionless relation as follows : Sh=1.898?Re?^0.514 ?Sc?^(1/3) For 235 < Re < 943 Cadmium ions reduction reaction was found to follow a first order reaction with respect to Cd+2 concentration, and reaction rate constant was predicted under different operating conditions.
