Description
Summary:The rate-based steady-state model proposed by Gabrielsen et al. (Gabrielsen, J.; Michelsen, M. L.; Kontogeorgis, G. M.; Stenby, E. H. AIChE J. 2006, 52, 10, 3443−3451) for the design of the CO2−2-amino-2-methyl-propanol absorbers is adopted and improved for the design of the CO2−monoethanolamine absorber. The influence of the application of different mass transfer correlations on the model’s performance is investigated. Analytical expressions for the calculation of the enhancement factor for the second order as well as the pseudo-first-order reaction regime are integrated in the model, and their impact on the model’s prediction is compared. The model has been successfully applied to CO2 absorber packed columns and validated against pilot plant data with good agreement.
