Deskripsi
Extractive distillation of cyclohexane – benzene – ethylbenzene – n-propylbenzene mixture with aniline as separating agent in complexes with partially thermally coupled columns was investigated. Manifold of the workable flow sheets were synthesized. Each flow sheet was optimized by the criteria of the scheme minimum energy consumption. The optimal flow sheet was found which is characterized by the energy consumption 17% lower as compared to the best one with two-outlet columns.
