This paper covers two methods for the prediction of liquid-liquid equilibrium data in ternary systems consisting of two hydrocarbons and a solvent and forming two liquid phases. One method is that of Pennington and Merril (ii) and the other is that described by Treybal (16), with some simplifying assumptions by the author. Both methods were applied to seven ternary systems in the present study. Five of the systems investigated were found to give rood agreement with experimental results. The assumptions made in deriving the equations for the two methods of prediction did not hold for the other two systems and that is why these two systems shamed disagreement between predicted and experimental results. As for comparison between thr two methods of prediction, they both gave good results, when applicable. The method of Pennington and Tamil (11) is recommended, because it is the simpler of the two methods.
