due to the importance of investigation in the field of CO2 capture, in this work a model based on GE-EoS mixing rules is represented to study alkanolamine-CO2-water systems. Vapour-liquid equilibria for 5 methyldiethanolamine (MDEA) solutions with 5 different amine concentrations, and 30 mass% 2-amino-2-methyl-1-propanol (AMP), and 30 mass% monoethanolamine (MEA) in different temperatures are calculated using Peng Robinson (PR)equation of state and Wong-Sandler (WS) coupled with UNIQUAC activity coefficient model. Calculated pressures are compared with experimental data and model parameters are obtained. Average absolute deviations show the low amount of errors
