SINGLE PARAMETER EQUATION FOR PREDICTION OF MULTICOMPONENT VAPOR-LIQUID DATA FROM BINARY ISOBARIC DATA

A single parameter Wilson equation that is suitable for use with isobaric systems is presented. Parameters for both the original and modified equations are obtained from isobaric binary data and from infinite dilution activity coefficients and then used to predict multicomponent vapor-liquid data for systems up through a quinary. Satisfactory results were obtained from the use of infinite dilution activity coefficients and the sensitivity of the final result to the accuracy of these end points is discussed.
