The degradation of aqueous diethanolamine (DEA) solutions by carbonyl sulfide was examined by using a 600-mL well-stirred reactor operating under the following conditions: DEA concentration 20--40 wt %, temperature 120--180 C, COS partial pressure 0.3--1.17 MPa. The reaction products were identified by GC/MS, and reaction mechanisms are developed which conform with experimental observations. The reaction rate constants are determined, and a mathematical model for estimating DEA degradation by COS is presented.
