Membrane Technology for Gas Separation
Membrane technology applied to the separation of gaseous mixtures competes with conventional unit operations (e.g., distillation, absorption, adsorption) on the basis of overall economics, safety, environmental and technical aspects. Since the first industrial installations for hydrogen separation in the early eighties, significant improvements in membrane quality have been achieved in air sepa...
متن کاملMathematical Modeling of Gas Separation Process with Flat Carbon Membrane
Carbon molecular sieve membranes (CMSMs) have been considered as very promising candidates for gas separation, in terms of separation properties as well as thermal and chemical stability. Due to the numerous advantages and wide applications of carbon membranes, their application for gas separation is of special importance. Because of the importance of carbon membranes and a large number of stud...
متن کاملAn Effective Iterative Algorithm for Modeling of Multicomponent Gas Separation in a Countercurrent Membrane Permeator
 A model is developed for separation of multicomponent gas mixtures in a countercurrent hollow fiber membrane module. While the modelâs solution in countercurrent module usually involves in a time consuming iterative procedure, a proper initial guess is proposed for beginning the calculation and a simple procedure is introduced for correcting the guesses, hereby the CPU time is decreased ess...
متن کاملfabrication parameters of asymmetric mixed matrix matrimid-mil-53/pmhs membrane for co2/ch4 separation
asymmetrically mixed matrix matrimid-mil-53 membranes with silicone cover layer were fabricated. for better understanding of membrane fabrication process, three main parameters of fabrication, matrimid concentration, silicone concentration and weight percentage of metal organic framework (mil-53) particles, were optimized by an experimental design method. cross-section sem images were used to s...
