•
VLE of CO2 in aq. (MDEA + PZ) and (MDEA + PZ + sulfolane) measured in an equilibrium cell.
•
Model validated with literature and experimental data. Estimation of species and pH.
•
PZ promotes CO2 absorption while sulfolane acts as physical solvent in aq. medium.
•
(MDEA + PZ + sulfolane) blend can be an efficient hybrid solvent for CO2 capture.
