Recently, membranes have found wide applications in gas separation processes. Having a proper model for simulation of the membrane behavior is very useful in achieving guidelines for design and characterization of membrane separation units. In this study a model with the base of Coker and Fleming’s work was developed. This model uses numerical methods to solve the coupled differential mass balance governing equations. In addition of determination of the performance for a membrane separation unit, this model can also be used for calculating the area required for a specific separation for all of the flow patterns in hollow fiber membrane modules. Results of the model for binary and multi component gas mixtures have shown good consistency with experimental data. With this model the effect of pressure and sweep or purge gases on performance and area required, can be investigated. Also with the aid of this simulation, cost of the membrane separation units can be estimated and the best condition for minimizing this cost can be selected.
