| Abstract | In this work, CO2 solubility in aqueous potassium lysinate solutions has been measured for the concentrations of (1.25–3.28) mol·kg−1 and at temperatures of (313–343) K. The vapour-liquid equilibrium data were correlated using a Soft model and a semi-empirical (SE) model. The proposed models can match well with the experimental data with AAD within 20%. The heat of absorption for LysK was estimated as about (55–70) kJ·mol−1 CO2 absorbed from the solubility data. The lower heat of absorption, compared with that of 30 mass% MEA, will be beneficial for the reduction of regeneration energy. |
