The results also show that the new model compares favorably with existing empirical analytical methods. Moreover, the predicted K factors provide remarkable results for such a simple model when used in a variety of phase equilibrium calculations. Results show the method to accurately correlate and predict the K value data, within 10% on average. The modification is based on correlating a subset of a database of K values, established from convergence pressure data. This work presents a new modification of the Wilson Equation for estimating phase equilibrium K values, predominantly for light hydrocarbon mixtures.

There have been several empirical analytical equations such as Raoult’s Law, the Hoffman Equations (Hoffman A, Crump J, Hocott C. Phase equilibrium K values are either estimated with empirical correlations or rigorously calculated based on fugacity values determined from an equation of state.
