The energy saving extractive distillation flow sheets of cyclohexane-benzene-ethylbenzene-n-propylbenzene mixture with aniline as separating agent. I – Complexes of the columns with two outlets

The extractive distillation was investigated of cyclohexane-benzene-ethylbenzene-npropylbenzene mixture with aniline as separating agent in the complexes of columns with two outlets. The manifold of the workable flow sheets was synthesized. The each flow sheet was optimized by the criteria of the scheme minimum energy consumption. The optimal flow sheet was found which characterized by the energy consumption lower than other ones for 50-75%.
