Abstract

Extended UNIQUAC thermodynamic framework was implemented in this work to model the aqueous blend of N, N-Diethylethanolamine (DEEA) and N-Methyl-1,3-diaminopropane (MAPA) for CO₂capture. The model parameters were estimated first for the two ternary systems, H₂O-DEEA-CO₂and H₂O-MAPA-CO₂, followed by the quaternary H₂O-DEEAMAPA-CO₂ system which gives liquid-liquid phase split when reacted with carbon dioxide. A total of 94 model parameters and 6 thermodynamic properties were fitted to approximately 1500 equilibrium and thermal experimental data consisting of pureamine vapor pressure (P^vap), vapor-liquid equilibrium (VLE), solid-liquid equilibrium (SLE), liquid-liquid equilibrium (LLE),excess enthalpy (H^E), and heat of absorption (ΔH_abs) of CO₂ in aqueous amine solutions. The model developed in this work canaccurately represent the equilibrium and thermal data for the studied systems with a single unique set of parameters.
