| 摘 要： | 本文提出了拟二元模型和状态方程联用的方法,计算加压情况下CO_2-CuAlCl_4·(C_6H_5CH_3)_n体系的气-液平衡数据.选用拟一元模型得到的CuAlCl_4·(C_6H_5CH_3)_n的表观临界参数和表观偏心因子作为状态方程中含盐非水溶液的特征参数.由实测的气-液平衡数据拟合了状态方程中的二元可调参数.考察了两种混合规则对计算精度的影响,发现修正混合规则后的P-R方程比原始的P-R方程具有更高的关联精度.计算表明,能用拟二元模型和状态方程来描述该体系的气-液平衡关系.

| Abstract: | A method of coupling a pseudo-binary model with equation of state was presented for the calculation of the gas-liquid equilibrium(GLE)data of a CO2-CnAlCl4(C6H5CH3)n system at elevated pressure. The apparent critical parameters and the apparent eccentric factors obtained by the pseudo-unitary model were used as characteristic parameters of these non-aqueous salt-containing solutions. Regressions of two adjustable parameters of P-R EOS were obtained by the experimental GLE data. Taking the effect of the mixing rule on the accuracy of calculation into consideration, it was found that the P-R equation was greatly improved by employing the modified mixing rule. Results obtained showed that the pseudo-binary model coupled with the EOS method could be used for the GLE of the type of system under study. |
