Based on these experimental data, the applicability of six empirical correlations for calculating critical properties of Talimu oil fractions were investigated. The average relative error is 1.35%～2.09% for critical temperature and 7.06%～9.96% for critical pressure. Among these correlations, Sim-Daubert and Lee-Kesler correlations are better for critical temperature calculation and better result for critical pressure calculation was obtained by Sim-Daubert correlation, while others are not satisfactory.展开更多
