The experimental results showed that the best performance of the absorption of CO_2 was achieved under the mass ratio of MDEA to PZ of 10/4 in the MDEA-PZ binary system. In the MDEA-PZ-MEA/DEA/ETA/TETA ternary system, due to the different molecular structure of the additives, the absorption performance of CO_2 was determined as follows: MDEA-PZ-TETA>MDEA-PZ-ETA>MDEA-PZ-MEA>MDEA-PZ-DEA. In the MDEA-PZ- TETA ternary system, the better absorption performance could be reached at the volume ratio of MDEA-PZ to TETA of 1:2. Moreover, it was indicated that there was a weakly negative interaction among MDEA, PZ and TETA. 收起
