heal.abstract	A recently developed EoS/GE model, the LCVM one, is applied to the prediction of Henry constants of nine gases (O2, N2, CO2, CO, H2S, CH4, C2H6, C3H8, C4H10) in a wide range of pure and mixed solvents, including heavy hydrocarbons, polar solvents, and water. When not available, LCVM interaction parameters are estimated by correlating vapor-liquid equilibrium data. LCVM yields very good predictions for Henry constants in pure solvents, with typical errors less than 8%; it also performs very satisfactorily in the prediction of high-pressure vapor-liquid equilibria. On the other hand, widely-used EoS/GE models, such as PSRK and MHV2, are shown to result in progressively poorer behavior with increasing system asymmetry. Finally, LCVM predictions for Henry constants in mixed solvents are also satisfactory, especially when combined with the method of Catte et al. The results presented here, combined with those from previous ones, render LCVM a valuable tool for predicting vapor-liquid equilibria. © 1995 American Chemical Society.	en
