Abstract: The heat of absorption is a critical thermodynamic property for establishing new solvents for CO2 capture. Experimental data for this thermodynamic property in the literature is limited. This study aims to determine the heat of absorption for new solvent compositions, which can potentially reduce energy consumption in solvent regeneration processes. The obtained heat of absorption data for CO2 in these solvents will contribute to the development of an Extended UNIQUAC model for the corresponding electrolyte system.
