Permeation behavior of pure gases (CO2, N2, CH4) and ternary gas mixtures of CO2, CH4, and H2S through a poly(ester urethane urea) membrane was investigated at different pressures, temperatures, and feed compositions. Permeances of CO2, CH4, and H2S through the membrane were determined at temperatures of 35, 45, and 55 °C, and pressures of 10, 20, and 30 bar. Effects of temperature, pressure, and stage cut on the permeability of gases through the membrane were experimentally studied. Since the main objective of this study was to evaluate the aforesaid membrane for its ability to remove acid gas application, the measured selectivity of poly(ester urethane urea) in this study was compared with that of some other polymeric membranes at nearly the same operating conditions. Maximum selectivities of 43 and 16 were measured for H2S/CH4 and CO2/CH4, respectively. Average permeances of 95 and 45 GPU for H2S and CO2 were achieved, respectively. | | En ligne : | http://pubs.acs.org/doi/abs/10.1021/ie071493k |
