A novel methodology for the modeling of CO2 absorption in monoethanolamine (MEA) using discrimination of rival kinetics

This paper suggests a new approach for the design of a multi-phase reactor and its optimization, focusing on close interaction among the laboratory experiments, rigorous modeling of reaction system, and design of reactors. A new methodology of “discrimination of rival kinetics” was developed to obtain a set of accurate kinetics for the identified reaction mechanisms, and this approach allowed us to develop more robust reactor design by making full use of the experimental data, avoiding unnecessary laboratory experiments. A case study of ‘CO2 absorption in an aqueous monoethanolamine solution’ in a packed bed reactor was used to illustrate the methodology.
