本课题是对所选CO的相平衡行为进行实验研究；i2 +烃二元和三元混合物，有助于理解CO的相平衡行为；2 -提高采油系统。同源系列CO二元混合物的气-液、液-液-气、固-液-气相平衡对I2 +正烷基苯进行了研究。三元混合物CO的液-液-气相平衡；研究了i2 + n-壬烷+丙烷，以评估轻烃物种的存在如何扩展原型CO的三相区；热力学相空间中的I2 +烃体系。研究在-60℃的温度范围内进行；到125；soC压力高达2000psia。

This project is an experimental study of the phase equilibria behavior of selected CO;i2 + hydrocarbon binary and ternary mixtures, which can contribute to the understanding of the phase equilibria behavior of CO;i2 - enhanced oil recovery systems. Vapor-liquid, liquid-liquid-vapor, and solid-liquid-vapor phase equilibria of the homologous series of binary mixtures of CO;i2 + n-alkybenzenes are studied. Also, the liquid-liquid-vapor phase equilibria of the ternary mixture CO;i2 + n-nonadecane + propane are studied in order to assess how the presence of a light hydrocarbon species extends the three-phase region of a prototype CO;i2 + hydrocarbon system in thermodynamic phase space. The studies are performed in the temperature range of -60;so to 125;soC at pressures up to 2000 psia.
