Abstract

A comprehensive numerically solved absorption-rate/kinetics model that takes into account the coupling between chemical equilibrium, mass transfer, and the chemical kinetics of all the possible chemical reactions involved was developed for the absorption of a gas into a reactive liquid. Also, absorption rate measurements to determine the kinetics of the process were obtained in a laminar jet absorber and used to validate this new model. The results show that the model used in conjunction with our numerical method is capable of predicting the gas absorption rates, enhancement factors, and the kinetics of the reaction. Also the model predicted kinetic data for the absorption of CO 2 into monoethanolamine (MEA) solutions that were found to be in accordance with published kinetic data. These results show that the developed numerically solved absorption-rate/kinetics model is both accurate and efficient.
