In this paper, a 3D modeling of Hydrogen separation from H2/N2 mixture by pd/α-Al2O3 Hollow fiber membrane in steady and unsteady state using computational fluid dynamic was considered. The effect of operating condition such as temperature, pressure and feed flow rate on concentration polarization was examined . By using concept of concentration polarization, controlling mass transfer in membrane module can be determined. Also by using sensitivity factor of flux that is used for analysis of concentration polarization, the best performance membrane can be found. The CFD results show good agreement with experimental data. . Comparison the results of simulation with experimental data show good agreement.
