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...
Dynamics of a Polymer in the Presence of Permeable Membranes
We study the diffusion of a linear polymer in the presence of permeable membranes without excluded volume interactions, using scaling theory and Monte Carlo simulations. We find that the average time it takes for a chain with polymerization index N to cross a single isolated membrane varies with N as N, giving its permeability proportional to N. When the membranes are stacked with uniform spaci...
متن کاملCO2-Responsive polymer membranes with gas-tunable pore size.
We report a smart polymer membrane whose pore can be switched between the "closed" and "open" state just by passing CO2 and Ar in solution respectively. Compared with other stimuli, such as pH or temperature change, gas is an environmentally friendly and cost-effective stimulus for reversibly tuning the pore size and imparting the size selectivity of the membrane.
متن کاملRecovery of ammonia from swine manure using gas-permeable membranes: effect of aeration.
The gas-permeable membrane process can recover ammonia from manure, reducing pollution whilst converting ammonia into an ammonium salt fertilizer. The process involves manure pH control to increase ammonium (NH4(+)) recovery rate that is normally carried out using an alkali. In this study a new strategy to avoid the use of alkali was tested applying low-rate aeration and nitrification inhibitio...
متن کاملRecovery of ammonia from swine manure using gas-permeable membranes: effect of waste strength and pH.
Nitrogen recovery from swine manure was investigated using gas-permeable membranes. The process involved a continuous recirculation of an acidic solution through a gas-permeable membrane submerged in manure. Ammonia from manure was concentrated in the acidic solution increasing its pH, while pH decreased in manure. In the first set of experiments, nitrogen recovery efficiency was evaluated with...
