【摘要】 针对Peng—Robinson状态方程式提出了新混合规则,其特点为协体积(Covolume)b的组合规则与组成有关。对22个二元非对称的含氢二元系统的汽液平衡计算表明,本研究取得了改进。进之将所推荐的混合规则推算了多元系统,也获得了满意的结果,从而为解决实际工程问题提供了依据。更多还原

【Abstract】 In the view of the Peng-Robinnson EOS,a new mixing rule,which contains the composition dependent combining rule for the covolume b,is proposed to describe VLE for 22 asymmetric binary hydrogen-containing systems, the results show that this work is an improvement on the previous studies. Using ehtproposed mixing rule, VLE for the multicomponent systems are calculated with satisfactory accuracies. In conclusion, the method provides a practical means for engineering application.更多还原
