We examine the simplest homogeneous azeotropic distillation sequence of industrial relevance, where we add an entrainer to a binary azeotrope in order to recover both azeotropic constituents as pure products despite its apparent simplicity, such distillation columns can exhibit an unusual behavior not observed in zeotropic distillation: - for some mixtures, separation as a function of reflux.
