Vapor-liquid equilibria (VLE) and liquid-liquid equilibria (LLE) for water-decane and water-squalane (C_<30>H_<62>) binary mixtures were correlated by Peng-Robinson Equation of State (PR EoS) at temperatures ranging from 573 to 637 K and pressures ranging from 1.3 to 31.2 MPa. The boiling point and critical constants of squalane were estimated from the specific gravity and molecular weight by using Nji method whose applicability to heavy hydrocarbon had been approved by comparing the prediction accuracy for the literature critical constants of paraffins, naphthenes and aromatics. Introduction of two temperature dependent binary parameters into mixing rules was revealed to provide good correlations and it was also suggested that the temperature dependence of volume binary parameter was omissible to reduce the number of parameters in calculations.
