Study of membrane system performance and HAZOP analysis in gas separation and reaction

چکیده
Introduction In order to separate efficiently a mixture, the designer has to create the conditions in which the components behave drastically different. These conditions depend mainly on chemical and physical properties of the species. Separation and purification methods take advantage just from differences concerning some specific properties of the mixture components that can be enhanced acting on temperature and pressure or modifying the system by means of an additive.

متن کاملAsymptotic Analysis of Binary Gas Mixture Separation by Nanometric Tubular Ceramic Membranes: Cocurrent and Countercurrent Flow Patterns
Analytical gas-permeation models for predicting the separation process across membranes (exit compositions and area requirement) constitutes an important and necessary step in understanding the overall performance of membrane modules. But, the exact (numerical) solution methods suffer from the complexity of the solution. Therefore, solutions of nonlinear ordinary differential equations th...
متن کاملPebax-Modified Cellulose Acetate Membrane for CO2/N2 Separation
Carbon dioxide (CO2) release from the exhaust gas streams of power plants that burn fossil fuels contributes the most emission of this gas, which includes more than half of the greenhouse effects. Thus, the separation of CO2 from exhaust gases is one of the main environmental concerns. Membrane technology, due to many advantages, has attracted many research attentions among the various gas sepa...
