In this study, the performance of gas-liquid membrane contactor for CO2 capture was investigated using a novel polysulfone (PSF) flat membrane prepared via non-solvent phase inversion method. Polyvinyl pyrrolidone (PVP) was used as an additive in the dope solution of PSF membranes. Morphological structure analysis using scanning electron microscopy (SEM) demonstrated that PVP-modified polysulfone membrane has a finger-like structure, but the other membrane has a sponge-like structure. Also, characterization results through atomic force microscopy (AFM) revealed that the porosity and surface roughness of the PSF membrane increased with addition of PVP to the dope solution. Evaluation of mass transfer resistance displayed that the resistance of PVP-modified PSF membrane is lower than that of the other membrane and addition of PVP to the dope solution significantly improved CO2 absorption flux up to 2.7 and 1.8 times of absorption fluxes of PSF membrane without PVP and commercial PVDF, respectively.
