Abstract

Equilibrium ratios of 29 impurities in aqueous solution of ethanol are expressed as functions of the concentration of ethanol. The constants of these functions have been determined by use of the vapor-liquid equilibrium data in the literature. A mathematical model of a pot-still is presented, in which open-steam heating, partial condensation and the passing of live steam are taken into consideration. The simultaneous differential equations are solved numerically and the distillation curves of the impurities are obtained. It is shown that the curves have characteristic shapes according to the type of minor component and are affected mostly by the concentration of ethanol in the charge. The calculated distillation curves are compared with the observed ones, which were obtained from papers on the production of distilled spirit.

各种杂质在乙醇水溶液中简单蒸馏的行为

29种杂质在乙醇水溶液中的平衡比表示为乙醇浓度的函数。这些函数的常数已用文献中的汽液平衡数据确定。建立了考虑开汽加热、部分冷凝和活汽通过的釜式蒸馏器数学模型。用数值方法求解了联立微分方程，得到了杂质的蒸馏曲线。结果表明，该曲线根据小组分的类型具有特征形状，主要受电荷中乙醇浓度的影响。计算所得的蒸馏曲线与实测的蒸馏曲线进行了比较。
