摘要
本文建立了由混合溶剂中电解质活度系数推算汽液平衡的数值计算方法。在电解质活度系数测定的盐浓度范围内,NaBr(1)-H_2O(2)-MeOH(3)和HCl(1)-H_2O(2)-MeOH(3)两体系在101.3 kPa下的汽液平衡计算结果与文献值平均绝对偏差分别为:汽相摩尔分率,平衡温度和,对前一体系还能正确地推测出交叉的盐效应规律。
Based on activity coefficients of electrolyte in mixed solvent, a numerical integration method for predicting VLE for electrolyte mixed solvent system was proposed. The VLE of two systems NaBr (1)-H_2O (2)-MeOH (3) and HCI-H_2O (2)-MeOH (3) were calculated. Within the concentration range for activity coefficient prediction, the average absolute deviation as compared to the literature value were | Dy_3 |=0.025, | DT| =0.40 K and | Dy_3 |=0.020, |DT|=0.76 K for above mentioned system respectively. In addition,The cross salt-effect in the system of NaBr (1)H_2O(2)-MeOH(3) could be predicted by this method.
