摘要：

In this paper, membrane absorption method was introduced. Analyzed and studied flue gases passing in the shell side (hollow fiber membrane) and in the pipe side (membrane lumen) respectively. Total mass transfer coefficient and de CO2 efficiency were calculated. For flue gases passing in the pipe side, total mass transfer coefficient was 1.1191x10(-4)m/s and de CO2 efficiency was 73.8%; while for flue gases passing in the shell side, total mass transfer coefficient was 3.470 x 10(-4)m/s and de CO2 efficiency was 98.0%. The results showed that the flow of flue gas flowing in the lumen is better than the flow of flue gas flowing out of the hollow fiber membrane from the point of views of removal rate and mass transfer. To build de CO2 experimental devices, flow of flue gas flowing in the pipe side was proposed.
