Removal of CO2 from natural gas and combustion exhaust gas have been studied by employing membrane permeation process. In these studies, polysulfone, polyimide and polydimethylsiloxane membranes are used to elucidate the influence of flexibility and rigidity of polymer as well as the influence of polar groups within polymer matrix on gas transport through membrane. The performance of the membranes as specified by its selectivity and permeation flux are measured in terms of the diffusion and sorption coefficients as well as the permeability. It is found that flexibility of the membrane tends to suppress its selectivity while enhancing its permeation flux. On the other hand, rigidity of the membrane together with the polar groups is shown to induce the opposite effects. In both cases however, the selectivity and permeation follow approximately the same qualitative variations with respect to concentration which is suspected to be caused by the politicization effect in the membrane. It is therefore concluded that a rigid polymer membrane with polar groups is most effective for its performance.
