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.
