Industry/University Cooperative Project: Phase Equilibria Behavior of Binary and Ternary Systems Relevant to C02 - Enhanced Oil Recovery (PUI)

该项目是对选定的CO；I2烃二元和三元混合物相平衡行为的实验研究，有助于理解CO；I2强化采油体系的相平衡行为。研究了CO；I2-正烷基苯同系二元混合物的汽液、液-液-汽和固-液-汽相平衡。此外，还研究了CO；I2正十八烷丙烷三元混合物的液-液-汽相平衡，以评估轻烃物种的存在如何在热力学相空间中扩展了原型CO；I2烃体系的三相区。这些研究是在-60；SO到125；SOC的温度范围内进行的，压力最高可达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.
