%X Piperazine (PZ) and 2-amino-2-methyl-1-propanol (AMP) as activators were added into methyldiethanolamine (MDEA) to form complex aqueous solutions, respectively. Mass transfer performance of CO2 absorption into the complex aqueous solutions in membrane contactors was studied. The effects of various factors, such as flowrates of gas and liquid, CO2 concentration of feed gas, absorbent concentrations of the solutions, CO2 loading in the solutions, configuration of membrane, and structures of modules on overall mass transfer coefficients of membrane contactors were investigated. Emphatically, the enhancement of mass transfer in membrane contactors was evaluated by means of comparison of chemical activation of sterically hindered amine AMP and multi-amino PZ in the complex solutions. The results show that multi-amino PZ has higher activation than sterically hindered amine AMP in complex solutions. The enhancement of PZ to mass transfer is higher than that of AMP in membrane contactors. The effect of hydrodynamics on mass transfer is limited. Chemical activation of activators is the key influential factor on mass transfer. Reaction kinetics plays a significant role in mass transfer.
