In the present work, the values of kLE were calculated, and the typical value is 10-2 m s-1 for 3.6 M aqueous MEA solution + CO2 system. Then the mass transfer
coefficient in liquid phase is of the same order of magnitude as that in the gas phase, and if the concentrations of MEA solution increase, the values could be higher and even kG kLE. Thus, the gas phase resistance cannot be neglected for the fast chemical reaction system.
