Abstract

Based on the computerized analysis of non-ideal mixtures, the authors reveal that the criterion of minimum normalized entropy production on the feed stage ( phi -criterion) is generally insufficient to choose the optimum location of the feed stage. A more appropriate method is to determine the maximum separation which can be reached by the total distillation column, characterized by the maximum entropy consumption or by the maximum ″separation efficiency″ . However, the phi -criterion yields a better average result than the cnventional criterion based on minimizing the sum of squares of the differences between the feed and stage mole fractions.
