Optimal design and control of an industrial distillation system
In this paper, an industrial distillation system, designed in a traditional manner without considering the interactions of design and control, is introduced and shown to be severely ill-conditioned. Through rigorous modelling and sensitivity analyses, a new control scheme is first proposed for overcoming the operational difficulties. A simultaneous optimization approach is then implemented to highlight the economic and operability benefits that could have been obtained if design and control interactions had been systematically considered in the first place.
