Absorption rates of CO 2 into aqueous solution of N -methyldiethanolamine (MDEA) blended with diethanolamine (DEA) were investigated by a laboratory disk column, in the temperature range from 313 to 343 K and a weight ratio of MDEA to DEA of from 50/3 to 50/10 at a total amine concentration of 3.0 M. According to the suggested homogeneous activation mechanism, kinetics of model of CO 2 absorption into aqueous solution of MDEA blended with DEA was established and the absorption rate can be expressed as N CO 2 = H CO 2 ( p CO 2 − ). An equation of second-order reaction rate constant between CO 2 with DEA, ln k DEA = 24.515 − 5411.3/ T, has been obtained, and it is in good agreement with that of literature reported on CO 2 absorption into single DEA aqueous solutions.
