Abstract
A numerical analysis was performed for a separation of carbon dioxide and methane using 2-staged, membrane process where two polysulfone hollow fiber membrane modules were connected to provide both the methane concentration richer than 95% and the recovery higher than 90% using the recycled flows. The Compaq Visual Fortran 6.6 software was utilized for the numerical simulation. Both the methane concentration and the recovery % of methane could be successfully predicted as the function of the operating conditions. As the feed pressure, the methane concentration, and the flow rate increase, the methane concentration in a product is also found to increase and the recovery of methane is found to decrease.
