In this work, the solubility data of CO 2 in aqueous blends of N-Methyldiethanolamine, Piperazine and Arginine (MDEA/PZ/ARG) of a total concentration of two moles is presented. CO 2 partial pressure was varied from 9 to 99 kPa while temperature ranged from 293 to 323 K in increment of 10 degrees. The experimental results showed that the solubility of CO 2 decreased with increasing ARG ration in the mixture. These results were modelled using a semi-empirical (SE) vapor liquid equilibrium (VLE) model. The model was found able to adequately represent the experimental data with an average absolute deviation (AAD) less than 3.13 %. Using a truncated form of the semi-empirical model, the heat of CO 2 absorption, ΔH ab , at low pressure was estimated and found to be in the range of 32-66 kJ/mole CO 2 absorbed.
