In this work, CFD (Computational Fkluid Dynamics) simulation of mass transfer in PEBA(poly Ether Block Amid)(grade 1657)/SiO2 nanocomposite membranes for gas separation process was performed. To our best knowledge, there is no evidence about the application of the nanocomposite membranes simulation. A 2D methematical model was developed to study the mechanism of CO2, H2, N2 and CH4 transport through PEBA/SiO2 nanocomposite membranes. Axial diffusion in the membrane was considered in the model. Moreover, convection in the down (low pressure) and up (high pressure) sides of the cell was also considered in this model. The final results were validated with the experimental data obtained from literature for gas permeation, sorption and diffusion through PEBA/SiO2 nanocomposite membranes. The modeling predictions were in good agreement with the experimental data. The simulation results showed that, with increasing the loading content of nanoparticles from 0wt% (the pure PEBA membrane) to 8wt% at 25˚C and 2 bar, the CO2 permeability increased.
