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.
