Compositional Modeling of Wax Formation in Petroleum Mixtures
Heavy organics deposition is a common problem in oil industry, especially in oil production, transportation and processing. Wax or solid paraffin series are examples of heavy organics that deposit. Precipitation and crystallization of wax causes major difficulties in different processes. Based on multi-solid theory, a basic model is modified in this paper for wax precipitation in different oils...
متن کاملSolid Phase Equation of State Application for Wax Formation Prediction in Petroleum Mixtures
Precipitation ofsolid paraffins is one ofthe most common problems in the oil industry, imposing high operating costs. There have been a great many efforts for the prediction <span style="font-size: 10p...
متن کاملPetroleum distillate solvents as risk factors for undifferentiated connective tissue disease (UCTD).
Occupational solvent exposure may increase the risk of connective tissue disease (CTD). The objective of this case-control study was to investigate the relation between undifferentiated connective tissue disease (UCTD) and solvent exposure in Michigan and Ohio. Women were considered to have UCTD if they did not meet the American College of Rheumatology classification criteria for any CTD but ha...
متن کاملEfficiency of Different Extraction Solvents on Recovery of Histamine from Fresh, Frozen and Canned Fish
Background: Histamine is a food-borne chemical hazard which causes scombroid poisoning. The efficiency of histamine recovery from fish is greatly influenced by selection of an appropriate extraction solvent. Hence, in this study the efficiency of different extraction solvents on recovery of histamine from fresh, frozen and canned fish was evaluated. Methods: Fresh, frozen and canned rainbow tr...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
