Abstract

Abstract: Critical temperature(Tc),critical pressurc(PC),and eccentric factor(ω)of heavy oil inKaramai 9th district heavy oil have been calculated by means of the average structure param-eters of the oil and group contribution technique. The heavy oil was treated as a pseudo purecomponent in the calculation and the values obtained are 879 K,0.866 MPa and 1.10 respec-tively.The characterization parameters and the Peng-Robinson equation of state have beenused to calculate the solubility of N₂,CO₂,and CH₄ in this heavy oil;The calculated resultsand the experimental data agree very well.The binary interaction coefficient involved in themixingrules of the equation state have also been discussed.

摘要： 将克拉玛依九区稠油看成假一元组分,用此稠油的平均结构参数和基团贡献法相结合的方法计算了此碉油的临界温度(Tc)、临界压力(Pc)和偏心因子(ω),其数值分别为879K、0.866MPa和1.10.这种计算方法不需稠油的任何物理性质(如正常沸点等).对于组成复杂、分子量高的混合物特性参数(Tc、Pc、ω)计算,此方法有明显优点.用计算的特性参数和Peng-Robinson方程关联、计算了克拉玛依九区稠油分别与N₂、CH₄、CO₂组成体系的泡点压力和相互作用系数.泡点压力的计算值与实验值一致性很好.
