Flexible startup, shutdown and product changeover procedures are necessary in today's chemical industry. The startup of chemical processes, such as distillation, represents one of the most complicated procedures in industrial practice. The computational and experimental results show that the optimal control policies can improve the operation performance with time saving of up to 45 %. This allows a significant reduction of energy and raw material consumption also and consequently can lead to a more economical process.
