In this study, capture of CO 2 and H 2 S from natural gas mixture using porous polymeric membranes has been investigated numerically to assess the capacity of a novel absorbent, di‐isopropanol amine (DIPA), in CO 2 removal. Diffusion of acid gases through porous polymeric membranes was simulated by employing CFD techniques and considering a gas feed stream, a porous membrane and a reaction medium. For solving conservation equations, finite element method was applied to calculate the rate of CO 2 and H 2 S absorption in the membrane. The type of membrane in this work is a hollow‐fiber module. According to the modeling results, a high H 2 S removal can be achieved by DIPA absorber. Moreover, CO 2 was captured from natural gas in an efficient manner in low gas/liquid flow rates. POLYM. ENG.
