Abstract

This study focuses on the thermodynamic modeling of CO2 absorption in aqueous solutions of N,N-diethylethanolamine (DEEA) using electrolyte NRTL model. Thermodynamic modeling of DEEA-H2O-CO2 system was developed by considering the pure vapor pressures, excess enthalpies, dielectric constants, physical solubilities of CO2, partial and total pressures experimental data. The correlated results were compared favorably to experimental data from the literature. The thermodynamic model developed in this work can be used for CO2 absorption-regeneration process simulation of DEEA-based aqueous solutions.
