Abstract: تم في هذا البحث دراسة عملية التحميض بصورة عامة وتحميض طبقتي ( التنومة والخصيب) المنتجة ) ضمن حقول EB - 91 للنفط والواقعة ضمن حقول شرقي بغداد بصورة خاصة. وتم اعتماد البئر (.(Case Study ) شرق بغداد كـ نموذج تعتبر عملية تحميض الابار النفطية من العمليات ا | In this work, acidification process in general and in particular at Al - Tanuma and Khasib layers is studied. Al - Tanuma and Khasib layer's in well (EB - 91)are located in east of Baghdad oil field. That well was taken as a case study.Acidification process is important to increase productivity of old oil well, and new one. Before acidification a test was carried out with water. During the test water is injected in these two layers under high pressure. If the test is successful that means the two layers are able to absorbed the dilute acid. - At first acid concentration must be diluted for 30 % to 15 % by using water as dilutent. - Additives are added to the acid, these additives are : • Anti - corrosion (A1 - 48) 0.5%.• Anti - emulsifier (NE - 50) 0.5%.• Emulsifier (WFT - 9256) 0.5%.• Solvent (WMS - 121) 1%. - Acid and the additives were injected inside Al - Tanuma and Khasib layers under high pressure. - Displacement liquid (gas oil) was injected inside the two layers to remove the acid and let it enter the formation. - The well was closed for minimum (1) hour to complete the reaction of acid with well formations. - The well was opened.The crude oil, gas oil and remaining acid will elute from the well by the action of pressure. - The crude oil eluted from the well was transferred by fire pipes to burning hole, where it was burned for about (3 - 4) hours. - After burning process is completed the well is ready for production.

اختيار الافضل للمفاعل النازل لوحدة التكسير بالعامل المساعد == Optimization Technique of Fcc Downer Reactor

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: 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%).
