Generalized multicomponent equation for activity coefficient calculation
A new model for the prediction of liquid phase activity coefficients used for predicting multicomponent phase equilibria is presented and compared with presently available methods for making these calculations.

Summary: | A new model for the prediction of liquid phase activity coefficients used for predicting multicomponent phase equilibria is presented and compared with presently available methods for making these calculations. In its binary form, the new model includes Margules, van Laar, NRTL, Scatchard‐Hamer, and Fariss models as special cases. In its multicomponent form the van Laar, Margules, and Scatchard‐Hamer forms are different from and superior to the Wohl expansion. It is also possible with the new model to use different special case models for each of the binary pairs. |
