三元液—液平衡关联式的热力学一致性检验

本文提出了三元LLE(Liquid—Liquid Equilibrium)关联式热力学一致性检验的方程式和由三元LLE实验数锯回归活度系数方程中参数的目标函数。用NRTL方程举例计算,对文献的关联结果作了检验,证明所提出的方程式和目标函数是比较好的。

Thermodyamic Consistency Test of Ternary Liquid—Liquid Equilibrium Correlation

This paper proposes an epuation of thermodynamic consistency test for ternary lipUid—lipuid epuilibrium(L L E) correlation, and an objective function to determine the Parameters of activity Coefficient equations from ternary L L E experimental data. An illustrative example has been shown for calculations with N R T L equatcon, by which a test for some correlating result of literature was made, it is well to be proved that the present eqatian and objective functcon are better than those of the Literatures.
