The scope of Danckwerts' model has been extended to explain all the published results on CO2-alkanolamine system in general, and CO2-diethanolamine (DEA) in particular. It has been shown that the order with respect to DEA varies depending on the concentration of DEA. At low concentration and at high concentrations of DEA of commercial importance the order is one and of course different rate constants. It attains the value two for intermediate concentration of DEA. The kinetics of CO2-DEA system in the presence of potash could be satisfactorily explained. The proposed unified approach helps in resolving the dilemma of the Process Design Engineer.
