Abstract

Experiments were performed on the degradation of aqueous diethanolamine (DEA) solutions passing through a coiled heat transfer tube immersed in a constant temperature bath. The degradation rate was found to increase with temperature, DEA concentration and CO//2 partial pressure; it decreased with solution flow rate. The degradation was accompanied by the formation of a fouling deposit. A simple mathematical model is presented for predicting DEA degradation.
