Carbon dioxide absorption in aqueous monoethanolamine solutions

Abstract Experiments have been carried out on the absorption of carbon dioxide in monoethanolamine (MEA) aqueous solutions. A laminar liquid jet absorber was first used, and the results obtained (which covered the contact time range between 0·02 and 0·07 sec), showed good agreement with the penetration theory equations as well as with the kinetics of the mechanism of the chemical reaction which presumably takes place in the liquid phase. Eventually a disk column absorber was used. The results were reproducible, and have been correlated in compact form by an empirical equation. Interpretation of the data on the basis of the penetration theory equations appears to be only partially successful.
