| 摘 要： | 石油馏分的临界性质是重要的热力学性质,常用来确定石油馏分的相状态,并关联和计算其它热力学性质,是石油加工工艺计算所必需的基础数据。早在20世纪20年代,国外已经开始测定和研究石油馏分的临界性质。1936年Roess1]测定了八种基属原料油100多个石油馏分的临界温度和临界压力,并提出相应的计算式。30年代以来,又陆续发表了一些求定石油馏分临界温度和压力的经验图表及计算式2～4],其中有些计算方法仍然依据Roess的实测数据。长期以来,在我国的石油炼制及化工设计计算中,主要采用API炼油技术数据手册2]推荐的图表和经验关联式来求…

| Abstract: | Critical temperature and pressure of 24 wide and narrow fractions from Talimu crude were determined with the semi-sealed tube apparatus. 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. |
