A Dual-mode model interpretation of CO2/CH4 permeability in polysulfone membranes at low pressures
ABSTRACT An asymmetric membrane of polysulfone (PSf) was synthesized by phase inversion method. Permeation experiments were carried out between 2 to 5 bar pressure, and at temperatures 20 to 45°C. The dense-selective layer of PSf membrane presents regular thickness (about 5 µm), and was not possible...
