  abstract: A better model for the vapor-liquid equilibrium of acid gases in alkanolamine-water systems was developed. The model is based on the electrolyte-NRTL equation, the Soave-Redlich-Kwong equation of state, the Redlich-Kwong mixing rule, and the temperature and concentration dependent Henry's constant. The binary interaction parameters in the electrolyte-NRTL equation and those in the Henry's constant were regressed using the Box-Kanemasu method and the algorithm proposed by Dovi and Reverberi (1992). All the parameters were reported with their standard deviations. The interaction parameters between molecules in the electrolyte- NRTL equation were determined from MEA-water, DEA-water, MDEA-water, [Co2]-water, and [Has]-water systems. The model predicted the total pressures of these systems very well. The model was also extended to the MDEA-DEA-water system using the parameters obtained from thebinary systems. The result of the total pressure prediction for this ternary system is extremely good.The parameters from the binary systems were further used in the acid gas-alkanolamine-water systems, where the interaction parameters of molecule-ionic pair and ionic pair-molecule were regressed along with the parameters in the Henry's constant equation. The model represents the experimental data very well. It also can be used to predict the acid-gas partial pressures from the unrepressed experimental data reasonably well, except for the [H2S]-MDEA-water system, where inconsistencies of the experimental data are high.
