Abstract

Membrane technology is one of the most widely used methods in separation processes (i.e., gas separation). Considering the time and costs spent in experimental studies, CFD could efficiently predict the fluid behavior without conducting the experiment. In this work, separation of H2/N2 gas mixture is carried out with palladium-silver membrane deposited on ceramic support, using COMSOL Multiyphysics software for simulation purposes. The findings of this work indicate that an increase in the feed pressure, hydrogen mole fraction and the feed flow rate in the shell side would lead in an enhancement of the hydrogen permeate flux crossing over the membrane in the tube side. The results also reveal that there is a good compatibility of the present findings with the experimental data.
