摘要

根据汽液平衡的基本性质和气体在液体中溶解时的特殊情况

采用RK方程的维里展开式和正规溶液理论

推得了气体溶解度与温度、压力的函数关系式

并用它对不同温度下加压气体的溶解度进行了关联和外推计算.

Abstract

On the basis of the special conditions of dilute system at vapor liquid equilibria

an equation was proposed to relate the solubility of sparingly soluble gas in non-volatile solvent to temperature and pressure

by using the regular-solution theory and the Virial expansion for the Redlich-Kwong equa tion of state. The equation was used to correlate high-pressure gas solubility in non-volatile solvent at various temperatures. Compared with the Krichevsky-Ilinskaya equation

this method gave better results and simpler calculation procedure.
