In this work, a comprehensive model has been developed for desorption of carbon dioxide from hot potassium carbonate solution containing diethanolamine as promoter. The unpromoted hot potassium carbonate vapor-liquid equilibrium data has been used which seems to be correct in the low concentration of promoter. The model, which is based on penetration theory, incorporates an extensive set of important reactions and takes into account the coupling between mass transfer and chemical kinetics. Operating data for carbon dioxide desorption from DEA-hot potassium carbonate solution has been compared to model predictions
