Abstract: يتضمن البحث دراسة سلوك التاكل للصلب الكربوني في محلول ملحي من (3.5wt%NaCl) ومشبع طبيعيا بالهواء بوجود غاز CO2 المستخدم في انابيب النفط. وتم تصميم منظومة القطب الاسطواني الدوار (RCE) لانجاز الدراسة.واجريت تجارب الاستقطاب في ظروف الجريان المضطرب باستخدام | The present work is to study the corrosion behaveior of carbon steel, in naturally aerated 3.5wt% NaCl (brine solution) and petroleum products in presence of CO2. 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.

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.

Abstract: واحدة من التحديات في مصافي تكرير النفط الخام في الاونة الاخيرة هو الحد من محتوى الكبريت من النفثا الثقيلة الى الحدود الدنيا. في هذا البحث تم اخذ مواصفات محتوى الكبريت للنفثا الثقيلة بمعدل 632 جزء في المليون الى 2.5 جزء في المليون، في درجات حرارة التفاعل ( | One of the recent challenges in the petroleum refineries is the reduction of sulfur content of heavy naphtha to the new lower limits. In this reaserch, was taken the specification of the sulfur content of heavy naphtha at arrange 632 ppm to 2.5 ppm, The range of reaction temperatures is (35 - 175) oC and liquid hourly space velocity (LHSV) at range of (1.3 - 1.4) hr - 1 and hydrogen pressure is 35 bars.The simulators are useful tools to manage operation and to improve the profitability of the process. In this study, excel and Matlab program were developed to simulate hydrodesulferization process (HDS) in vapor phase reactor of heavy naphtha hydrotreating unit of Daura refinery, the comparison between the plan results with HDS reactor model results was made.. Based on the model results the optimum operating conditions were determined. Acomputer program MATLAB (Matrix Laborator) it is software for developed code of kinetic parameter estimation problem using the estimation method and least square as objective function and new GA as solving method. The code was implemented on personal computer (intel (R) Core (TM) i3 CPU, 2.39 GHz processor, 2 GB RAM). The function to be minimized was the sum of squares of the differences between calculated and measured concentration.Genetic optimization method was used to define the parameters of desulfurization reaction kinetic. This hydrotreating reaction kinetic model for desulfurization of Daura heavy naphtha was determined for heavy naphtha boiling point range of (35 - 175) C and using a commercial (HDS) catalyst cobalt - molybdenum (Co - Mo) supported of alumina.The result showed that the order of kinetic reaction was first order for heavy naphtha hydrotreating with (Co - Mo) supported of alumina, and the graphically method is more suitable and less error than optimization method for represent the kinetic reaction for heavy naphtha hydrotreating in Daura refinery.

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.
