Abstract
Phase equilibria of ternary ethane-propane-sunflower oil mixtures were measured at 313, 333 and 353 K, and at pressures of up to 120 bar. Th e region of partial liquid miscibility, at high hydrocarbon concentrat ion, was particularly explored. The Soave-Redlich-Kwong equation of st ate was used to fit experimental vapor-liquid and liquid-liquid equili bria of alkane-vegetable oil mixtures. The application of a quadratic mixing rule for the co-volume b with a binary interaction coefficient kb(ij) greatly improves the performance of the model.
