    Correlation of the Solubility of Solids in Supercritical CO2

      摘要
    • 摘要: 对压缩气体模型中P-R状态方程法(EOS法)进行了改进,并和其他改进方法进行了比较。为了验证改进模型的可行性,用流动法测定了水杨酸在超临界CO2中的溶解度并对数据进行了关联,对含有夹带剂的溶解度用改进的方法进行了关联,认为夹带剂的加入会增大溶质的饱和蒸汽压而导致溶解度的增加,关联计算精度很高。

       

      Abstract: The improved P-R EOS was used to estimate the solubility of solids in supercritical CO_2.Comparing with other improved P-R EOS,the accuracy was improved by estimation of saturated vapor pressure of salicylic acid when the co-solvent is used.The results show that the solubility correlations of solid are satisfying with the improved P-R EOS.
