Effect of different type of solvents on asymmetric polysulfone membrane for co2/ch separation

The objective of this study is to develop a high performance and defect free asymmetric polysulfone membrane for CO2/CH4 separation and to investigate the effect of different type of solvents on the performance of the polysulfone membrane. The membrane were developed consist of 20% polsulfone (PSU)...
