Effect of different type of polymer concentration on asymmetri polysulfone membrane for CO2/CH4 separation

The objective of this study is to developed polysulfone (PSU) asymmetric membrane for gas separation and to identify the concentration of polysulfone in dope solution to produce high selectivity membrane for CO2/CH4 gas separation. Polysulfone was selected as the polymer material in this research si...
