摘要
主要结合统计缔合流体理论(PC-SAFT),采用已有的CO2与甲醇纯流体分子参数,同时利用CO2与甲醇纯流体分子参数回归二元交叉作用参数。以CO2、甲醇的纯流体分子参数及回归所得的二元交叉作用参数作为输入,来关联和预测CO2-甲醇二元体系相平衡性质。本文不仅对CO2-甲醇二元体系p-x和p-ρ相图的预测结果与实验数据进行了比较,而且分析了温度、压力和两相密度等因素对CO2-甲醇二元体系界面性质的影响。
Combined with statistical associating fluid theory（PC-SAFT）,took the molecular parameters as an input derived from the simulated pure fluids,the phase equilibrium of supercritical carbon dioxide-methanol and carbon dioxide-ethanol binary systems in the determined range of temperatures were calculated and analyzed.The impact of temperature,pressure and two-phase density on the interfacial properties was analyzed.Finally,the calculated results of PC-SAFT equation were compared and analyzed with the experimental data.
