Abstract
The limit of the productivity of a binary distillation column is obtained depending on heat consumption. It is shown that the consumption of heat per mole of the mixture to be separated in a reversible process for multicomponent mixtures depends on the order of separation, and irreversible consumption is monotonically related to it. This allows reversible indicators to be used to select the order of separation. The problem of the expediency of using a separating agent to increase the efficiency of separating mixtures with close boiling points of the components is considered.

在蒸馏过程中使用分离剂的热力学效率
摘要
根据热量消耗来获得二元蒸馏塔的生产率极限。结果表明,在多组分混合物的可逆过程中,每摩尔要分离的混合物的热量消耗取决于分离的顺序,不可逆的消耗与其单调相关。这允许使用可逆指示器来选择分离顺序。考虑了使用分离剂以提高分离组分沸点接近的混合物的效率的便利性的问题。
