Prediction of CH4 permeation through polysulfone membrane by molecular modeling

The gas separation and permeation are one of the most important parts of chemical engineering processes. Gas permeation through polymeric membranes, because ofimportance of gas permeation in many industries, is very interesting for researchers. One of the most important components of natural gas is methane. In this study, it is tried to investigate the permeation of methane through polysulfone membrane. Diffusion and solubility coefficients will becalculated and as a result of them, the permeability coefficient is measured. Also, the fraction free volume has direct effect on permeation [1-3].
