Metal organic framework mixed matrix membranes for gas separations

Please cite this article in press as: R. Adams et Mixed matrix membranes (MMMs) for gas separations are traditionally comprised of zeolites dispersed in a polymer matrix in order to improve desired penetrant permeability and selectivity. Zeolites have a variety of drawbacks for this application – chiefly, a limited number of possible zeolite structures – that limit their potential for use in MM...

Modeling of Spiral-Wound Permeators for Multicomponent Gas Separations

Two multicomponent models for spiral-wound gas permeators are proposed. The basic transport model is derived from fundamental material balances and permeation relations that account for permeate-side pressure variations. The resulting model consists of a set of nonlinear differential-algebraic-integral equations with mixed boundary conditions, as well as an implicit expression for the local fee...

hazard 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...
