摘要：

The solubility of N2O in pure alkanolamines (MEA, DEA, DIPA, TEA, MDEA and AMP) has been measured over the temperature range from 20 to 85-degrees-C at atmospheric pressure and correlated as an exponential function of temperature. The densities of the pure alkanolamines were determined at temperatures from 20 to 90-degrees-C. A semiempirical model for calculating the solubility of N2O in amine mixtures is presented. The model is based on the work by Prausnitz and Chueh, by Prausnitz and by Boublik and Hala. Correlations of experimental N2O solubility data are carried out for eight systems (MDEA-H2O, AMP-H2O, DIPA-H2O, DEA-H2O, MEA-H2O, AMP-MDEA-H2O, AMP-TMS-H2O and DEA-EG-H2O) between 15 and 70-degrees-C over a large range of concentrations. Comparison with the experimental results indicates that the model should be reliable for estimating the solubility of N2O in alkanolamine mixtures with binary or ternary solvents. The solubility data for pure amines and the correlation for mixed solvents may be applied to estimate the solubility of CO2 gas in pure or mixed solvents assuming the N2O-CO2 analogy.
