Solubility of carbon dioxide in the solvent system (2-amino-2-methyl-1-propanol + sulfolane + water)

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) w1=16.5%w1=16.5%, w2=32.2%w2=32.2%; (ii) w1=8.2%w1=8.2%, w2=41.2%w2=41.2%; (iii) w1=22.3%w1=22.3%, w2=27.7%w2=27.7%; and (iv) w1=30.6%w1=30.6%, w2=19.4%w2=19.4%, where ww 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.
