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.
