Abstract
This paper considers the design and control of the separation of benzene and cyclohexane process via extractive distillation in a dividing wall column. To aid the separation, furfural is used as the heavy boiling entrainer. The optimal flow sheet with minimum energy requirements has been established using the multiobjective genetic algorithm with constrains. Three control strategies are proposed: the basic control strategy uses four composition controllers, and two improved control strategies with and without vapor split ratio use temperature controllers that are more practical in application than the basic control strategy. The dynamic simulations reveal that the three control strategies can object to the feed disturbances well. The dynamic responses of two improved control structures show that vapor split ratio as a manipulated variable can maintain the product purities at their set points when a feed disturbance is introduced.
