摘要：

The simplified Clegg-Pitzer equations are used to correlate the solubility data for CO2 and H2S in 0.5, 2, 3.5, and 5 M triethanolamine aqueous solutions at 0, 25, 50, 70, 75, 100, and 125 degrees C at acid gas loadings below 1.0 and partial pressures of the acid gases ranging from 0.01 to 6700 kPa. The interaction parameters thus obtained can be used to predict the solubility data for the mixed acid gases in CO2-H2S-TEA-H2O systems over a wide range of solvent composition, temperature, and pressure without any additional adjustable parameters.
