Consideration has been given to the problem on selecting a point for injection of a separated mixture into a multicomponent-rectification column in accordance with the dissipation minimum condition during the mixing of reflux and mixture streams. An estimate for the minimum entropy production in mixing has been found. The manner in which the irreversibility of the process of mixing at the injection point affects the region of permissible regimes of the column has been shown. An algorithm for calculating the concentration profile of the mixture’s components over the column height has been proposed.
