The aim of this study was to model experimental results obtained for the supercritical CO₂ fractionation of a liquid mixture containing 24% of sclareol in order to recover a raffinate with increased sclareol content. First, supercritical CO₂ fractionation experiments were carried out at pressures (10–12) MPa, and temperatures (313–338) K. Secondly, the modeling of the raffinate and extract compositions for 12 selected compounds including sclareol was performed using the group method. The modeling was carried out at a temperature of 323 K and pressures of (10–11) MPa, and at a temperature of 338 K and a pressure of 12 MPa. The calculation of the raffinate and extract compositions required the adjustment of the number of theoretical stages and of the distribution coefficients for the selected compounds. Experimental raffinate and extract compositions were represented by the model with a relative error of about 15%.

这项研究的目的是对包含24％香紫苏醇的液体混合物进行超临界CO ₂分馏所获得的实验结果进行建模，以回收香紫苏醇含量增加的萃余液。一，超临界CO ₂在压力（10–12）MPa和温度（313–338）K下进行分馏实验。其次，使用分组方法对包括香紫苏醇在内的12种选定化合物的提余液和提取物组成进行了建模。建模是在323 K的温度和（10-11）MPa的压力下，在338 K的温度和12 MPa的压力下进行的。提余液和提取物组成的计算需要调整理论级数和所选化合物的分配系数。该模型代表了实验提余液和提取物的组成，相对误差约为15％。
