Thermodynamic model has been developed for aqueous PZ-MDEA-CO2. Addition of PZ concentration increased CO2 loading of activated MDEA solutions. Addition of PZ is more effective at lower CO2 partial pressure. Increase in temperature decreases CO2 loading of activated MDEA solutions. The proposed model has been validated in comparison with experimental data.
