Abstract
Dynamic models of membrane permeators for gas separation have been developed. The models, consisting of a system of stiff nonlinear partial differential equations, were generalized into dimensionless forms, simplified by using the Quasi-Steady-State Assumption (QSSA), and solved by the orthogonal collocation method. Dynamic responses of the simple permeators to various disturbances in operating conditions are presented. The simulation results provide insight into the permeator dynamic behavior which is very useful for permeator control and design. The computer program used here is capable of simulating membrane separators of more complex configurations with slight modificationsKeywords
