固体溶质在含夹带剂超临界CO_2中溶解度的计算

Calculation of solid solute solubility in supercritical carbon dioxide with cosolvent

针对超临界流体萃取技术是一种绿色新型分离技术的特点,选用适合超临界体系特点的状态方程、混合规则及方程参数的计算方法,建立了计算溶质在含和不含夹带剂的超临界CO2中溶解度的数学模型,并给出了模型的计算过程。

Supercritical fluid extraction （SFE） is a promising new and green separation technology. In order to promote its ap- plication, based on the characteristics of supercritical system, the suitable equation of state, together with the modified mixing rule and the equation parameter, was proposed to calculate the solute solubility in supercritical CO2 with and without eosolvent respectively, and the calculating process was listed.
