Synthesizing distillation processes requires the identification of feasible separations. For this purpose, an algorithm for determining feasible separation regions for a ternary system is proposed in this paper. An analysis of feasible separation regions revealed that these regions are the union of two product composition sets. One of these sets is bounded by a generalized distillation limit and a product composition multitude. Conversely, the border of the second set is determined by the feed distillation line and a product composition multitude. These two product composition sets either overlap or one set includes the other. Each of these sets can be separately determined by implementing the same algorithm with appropriate limiting curves. The algorithm accounts for the type of column internal (trays or packing), type of condenser and reboiler, and feed quality. Applying the algorithm to a benzene–cyclohexane–acetone mixture can help realize a novel promising distillation system.

三元体系蒸馏的可行分离区域：一种算法

合成蒸馏过程需要确定可行的分离方法。为此，本文提出了一种确定三元系统可行分离区域的算法。对可行的分离区域的分析表明，这些区域是两个产品组成集的并集。这些组中的一组受广义蒸馏极限和产物组成众多的限制。相反，第二组的边界由进料蒸馏线和产物组成的多样性决定。这两个产品组合要么重叠，要么一个包括另一组。这些集合中的每一个都可以通过使用适当的限制曲线实施相同的算法来分别确定。该算法考虑了塔内部的类型（托盘或填料），冷凝器和再沸器的类型，和饲料质量。将算法应用于苯-环己烷-丙酮混合物可以帮助实现一种新颖的有希望的蒸馏系统。
