VAPOR-LIQUID EQUILIBRIUM CALCULATIONS USING NEW MIXING RULES COMBINING FUNCTIONALLY DIFFERENT EQUATIONS OF STATE

Abstract

On the basis of the three-parameter corresponding-states principle, new mixing rules combining functionally different equations of state were proposed. Vapor-liquid equilibrium calculations for several binary systems were carried out with the use of these mixing rules and equations of state of several types for each pure component.
As a result, these mixing rules are considered to be very useful for accurate prediction of vapor-liquid equilibria since they make it possible to use any type of equation of state developed specifically for each pure component.
