Simulation of an internally multi-staged permeation module operating with cocurrent flow pattern

Abstract

Performance of an internally multistaged permeation module for gas separation has been analysed using mathematical models based on cocurrent flow and perfect mixing. Simulation results obtained using the problem of oxygen enrichment from air indicated that, in an internally multistaged permeator the effect of the number of permeation stages on oxygen enrichment is significant when it is increased from one to two or three, and its effect decreases gradually with further increase in number of stages. A parametric study further revealed that the performance of the internally multistaged permeator with cocurrent flow yields better separation results than those obtained from the perfect mixing case.
