New sets of data for the solubility of CO2 in the amine solvent system of 2-amino-2-methyl-1-propanol (1) + sulfolane (2) + water (3) were presented in this work. The measurements were done at temperatures of 313.2, 333.2, 353.2, and 373.2 K and CO2 partial pressures up to 193 kPa. The investigated compositions were as follows: (i) w(1) = 16.5%, w(2) = 32.2%; (ii) w(1) = 8.2%, w(2) = 41.2%; (iii) w(1) = 22.3%, w(2) = 27.7%; and (iv) w(1) = 30.6%, w(2) = 19.4%, where w is the mass percent of the component. The present solubility data was correlated by a modified Kent-Eisenberg model. The model reasonably represents the present solubility data, not only over the considered conditions, but also for a wider range of temperatures, partial pressures, and compositions.
