A small hollow-fiber membrane contactor system was used to test the absorption and desorption CO2 using mixed absorption solution of SG/PG and TEA. The results showed that absorption effect of SG was better than PG under low concentrations, but their desorption was the opposite. With the increase of concentration, the absorption effect of SG tended to weak, while the desorption was enhanced. And, PG was contrary. The absorption effect of mixed solution(SG+TEA, PG+TEA) was excellent when adding small amount of TEA. And, the absorption effect of TEA-SG mixed solution was amazing under the low concentration of SG. With the concentration of mixed solution increased, the auxo-action of TEA weakened. Instead, TEA played a active effect on promoting the absorption of TEA+PG mixture with the increasing of concentration. The hybrid experimental results shown that 3mol/L PG+0.1 mol/L TEA mixture absorption solution was best in absorption experiments, and 1mol/L PG+0.2 mol/L TEA mixture absorption solution was best in desorption experiments.
