Abstract

The equilibrium solubilities of carbon dioxide in aqueous mixtures of 2-amino-2-methyl-1-propanol (AMP) with sulfolane have been measured at 40, 60, 80, 100℃, and at partial pressures of carbon dioxide ranging from 2 kPa to 193 kPa. The systems studied are aqueous 1.0 M AMP + 3.4 M sulfolane, 2.5 M AMP + 2.3 M sulfolane, 3.5 M AMP + 1.6 M sulfolane solution. The model of Kent and Eisenberg (1976) has been applied to correlate the measured data. Satisfactory results were obtained for calculation of the solubility of carbon dioxide in AMP/sulfolane/H2O solution for the system studied. The results of this study show that the absorption of CO2 has been greatly improved by using AMP/sulfolane/H2O over the conventional aqueous amine solution, i.e.AMP/H2O. Thus, the AMP/ sulfolane/H2O system should be one of the promising potential absorbents for CO2 absorption. This study can be used as a tool for vapor-liquid equilibrium calculations for designing the acid gases process using AMP/sulfolane/H2O solution as the absorbent.
