Abstract

This study is aimed at developing a simple and stable method for accurately calculating the three-phase compositions existing at equilibrium in VLLE region. Incorporation of a simple method for estimating initial K-values in the present algorithm allows this algorithm to more easily and accurately calculate the composition of each phase in vapor–liquid–liquid equilibrium. The old algorithms have not used the above method but used trial and error procedures (such as minimization of Gibbs free energy) which is more difficult and time consuming. Compared with the experimental data, the present method gives more reasonable results.
