|One of the most important parameters required to model the absorption of CO_(2) into aqueous alkanolamine solutions is physical solubility. However, since CO_(2) reacts in amine solutions, its physical solubility cannot be measured directly. As a result, a nonreacting gas which is similar to CO_(2) has to be used such as N_(2)O. The solubility of nitrous oxide (N_2O) in aqueous solutions of 0wt% - 50wt% MDEA, 0wt% - 30wt% DEA, and 50wt % total amine with DEA/MDEA molar ratios of 0.05, 0.25, 0.5, and 0.67 was measured using a modified Zipperclave reactor over a temperature range of 293-353 K with near atmospheric partial pressures of N_(2)O. The solubility data from this work were found to be in good agreement with previously reported data where available.
