摘要
精确的溶解度数据是超临界流体萃取工艺设备设计和操作条件选择的关键 ,本文采用Peng -Robinson状态方程对 15种固体在超临界CO2 中的溶解度数据进行了关联计算 ,溶解度的计算值与文献的实验值符合很好 ,其平均相对偏差均小于 10 %。
The accurate solid solubility data are a key to the design of process equipment and the selection of operating conditions for supercritical fluid extraction. The solubility data of fifteen solids in supercritical carbon dioxide are correlated and calculated by the Peng-Robinson equation of state in this paper. The results of calculation agree well with the experimental data from the articles, and the average relative deviations are all less than 10%.
