A COMPARISON OF DEHYDRATION PROCESSES OF Al-, Fe
Introdution: Hydrous sulfates (Ca-, Mg-, Fesulfates, and recently Al-sulfates) have been found on Mars by OMEGA (Mars Express orbiter) [1], CRISM (Mars Reconnaissance orbiter) [2], the Spirit and Opportunity rovers [3], and Phoenix lander [4]. Furthermore, the change in hydration degree of Fe 3+ -sulfates after exposed to the current Martian atmospheric condition was suggested by long-duration ...
متن کاملDesign and Optimization of Acetic Acid Dehydration Processes
Acetic acid is the most widely used aliphatic carbonic acid used as a reaction partner during the manufacture of acetic acid esters, or employed as a solvent in the production of cellulose acetate. Although acetic acid and water do not form any azeotrope, use of simple distillation to separate these two components is still not practical due to its high energy consumption rate. In this work, som...
متن کاملhazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures
شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Energy Efficient Hybrid Processes for Ethanol Dehydration: a Comparison of Benchmark and Membrane Assisted Configurations
One of the most promising processes for ethanol dewatering are hybrid separations consisting from different combinations of distillation with adsorption and/or vapour permeation. This paper presents a detailed process analysis showing the influence of decisive parameters on important target variables. The advanced mathematical models have been used for determination of optimal process configura...
متن کاملDynamic Behavior of Alternative Separation Processes for Ethanol Dehydration by Extractive Distillation
Ethanol is attracting the attention of researchers because of its potential in reducing the dependence on crude oil together with the possible reduction in the pollution associated with the combustion process. The ethanol dehydration process is significant in terms of its production cost. Recently, new distillation sequences have been proposed for the separation of pure ethanol from the ferment...
