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。By using of the P-R EOS, the new mixing rule Ⅱ, which was proposed n the first part of this paper(Ref. Chemical Engineering(China), No. 1, 990), is applied to simulation of the liquid nitrogen scrubbing towers for pufication of the syn gas in the ammonia plants. All binary interaction parameters are determined by VLE data for the constituent binary systems. Our simulation results for the towers are in good agreement with the data recommended by design companies.In conclusion,the approch developed in this work is applicable to engineering design.
