A prediction method of high pressure vapor-liquid equilibria by the BWR equation of state is presented. This method in terms of ratio of mole fractions in liquid phase can be used more easily than the usual method, and is particularly useful for multicomponent system for which experimental data are not available. This method is shown to be successful in the prediction of the ternary methane-n-pentane system and quinary methane-ethane-propanen-butane-n-pentane system.
