本文根据群集统计理论,提出了溶液的群子统计模型,进而推导了汽—液平衡组成关联式。该关联式通过简单的表式归纳了相对挥发度(a)、串入群子的速率比(r_1,r_2),群子的形态因子(a_1、a_2)及汽—液两元组成比(x_1/x_2,y_1/y_2)之间定量关系。实验数据的理论分析表明本文所提出的关联式具有很大的普遍性,并且给出相当良好的计算精度。为了检验本文模型的可靠性,选择了各种类型的汽—液平衡体系,并同其他计算方法(Margules、Van laar、Wilson、NRTL 和UNIQUAC 方法)的结果作了对比。其结果表明本文所提出的群子模型具有独特的优点。
Based on the theory of cluster statistics, this paper proposes a swarm statistical model of solution, and then derives the vapor-liquid equilibrium correlation. The correlation summed up the relative volatility (a), the rate ratios (r_1, r_2), the morphological factors (a_1, a_2) and the vapor-liquid two-component ratio / x_2, y_1 / y_2). The theoretical analysis of the experimental data shows that the correlation proposed in this paper is very universal and gives quite good calculation accuracy. To test the reliability of our model, various types of vapor-liquid equilibrium systems were selected and compared with those of other computational methods (Margules, Van Laar, Wilson, NRTL, and UNIQUAC methods). The results show that the proposed sub-model has unique advantages.
