In this study, polyether block amide (PEBA) was used to prepare PEBA/PSF (polysulfune) compositemembrane by dip-coating method for natural gas sweetening. SEM image was used to characterize the compositemembrane structure. The effect of transmembrane pressure on performance of the composite membranes was studied.The CO2 permeance was about 60 GPU and the membrane showed 24 ideal selectivity for CO2/N2 at transmembranepressure of 7 bar.
