The calculated results showed that the SRK equation with the T-type α function and the Chung–Twu (CT) mixing rules embedded in the UNIFAC–Lyngby model (SRK-T/CT–UNIFAC– Lyngby) not only predicts accurately the VLE properties of the constituent binaries but also represents the ternary LLE and VLLE phase behavior reasonably well. Using this model, the vapor pressure data of the pure constituent components are the only required property for the phase equilibrium calculations.
