Vapor-Liquid Equilibria, Correlation by Means of a Modified Redlich-Kwong Equation of State

The conventional method of correlating vapor-liquid equilibrium data is to separate deviations from ideality into deviations occurring in the vapor phase and deviations occurring in the liquid phase, and then to fit these deviations with separate thermodynamically consistent correlation expressions. By this method deviations from ideality occurring in the vapor are usually calculated from an equation of state and deviations from ideality occurring in the liquid are calculated with reference to the pure liquid component. This method has proved very useful, even at pressures approaching the critical pressure of a mixture and at temperatures above the critical temperature of a component [1–5].
