Stripping of carbon dioxide from monoethanolamine solutions in a packed column

Abstract

Abstract A procedure using only fundamental physico‐chemical data is developed for the design and analysis of packed columns used for solvent recovery in gas purification processes involving chemical reaction. The results of 173 experiments on the mass transfer performance of a pilot‐scale regenerator stripping CO 2 from loaded monoethanolamine solutions are reported and compared with model predictions. Anomolous responses of the overall mass transfer coefficient to changes in process conditions are observed and explained by the process model which is found to predict correctly both the magnitude of the coefficient and its response.
