Separation of CO2 from CH4 by pure PSF and PSF/PVP blend membranes : effects of type of nonsolvent, solvent, and PVP concentration

Complete CO2/CH4 gas separation was aimed in this study. Accordingly, asymmetric neat polysulfone (PSF) and PSF/polyvinylpyrrolidone (PVP) blend membranes were prepared by wet/wet phase inversion technique. The effects of two different variables such as type of external nonsolvent and type of solven...
