Kinetics of the reaction of carbon dioxide with aqueous solutions of 2-((2-aminoethyl)amino)ethanol

In view of increased requirements on absorption rates and loading capacity for carbon dioxide (CO2) absorption solvents, more research is directed toward alkanolamines having more than one amino group. In the present work, AEEA {2-((2-aminoethyl)amino)ethanol}, a diamine containing primary and secondary amino groups, is used to study the CO2 absorption kinetics. The reaction kinetics between CO2 and aqueous solutions of AEEA were measured over a range of temperatures from 32 to 49 degrees C with the concentrations of AEEA ranging between 1.19 and 3.46 kmol m(-3) using a string of discs contactor.
