The simplified Clegg-Pitzer equations are used to correlate the solubility data for CO{sub 2} and H{sub 2}S in 0.5, 2, 3.5, and 5 M triethanolamine aqueous solutions at 0, 25, 50, 70, 75, 100, and 125 C at acid gas loadings below 1.0 and partial pressures of the acid gases ranging from 0.01 to 6,700 kPa. The interaction parameters thus obtained can be used to predict the solubility data for the mixed acid gases in CO{sub 2}-H{sub 2}S-TEA-H{sub 2}O systems over a wide range of solvent composition, temperature, and pressure without any additional adjustable parameters.
