A simple regulatory control structure is proposed for the Eastman process that provides more effective control of the production rate than more compiler strategies previously proposed in the literature. Stripper bottoms is simply flow controlled, and level controls are arranged in a direction apposite to the process flows. Common heuristics are shown to provide an effective, stable control system. Drastic disturbances are easily handled by overrides. An important feature of the structure is the use of proportional-only controllers on all leaps in this integrating system.
