In the present study, a thermodynamic modeling using explicit model is performed for the determination of carbon dioxide solubility in blends of aqueous potassium lysinate with piperazine at a wide range of pressure from 500 to 4100 kPa, temperature within 303.15-343.15 K, and solvent concentrations of 1, 2 and 3 M. The model has suitably predicted the carbon dioxide thermodynamics of the solutions. The average absolute deviation from the correlation of the explicit model is found to be 8.5%.
