This study presents permeation characteristics of pure CO2, N2, and theirmixtures were examined by permeation experiments through hollow-fiberpolyimide and polysulfone membrane modules and experimental data were comparedwith simulated results. To good agreement with dual-mode transport theory, thepermeance decreases with the applied pressure. In the small applied pressure, theperformance of polyimide membrane for mixture permeation is well predicted fromnumerical results but that of polysulfone membrane is lowered in comparison withpure gas permeation. It is the plasticization effect by CO2 that cause the deterioration.
