Computer control in the polymerization industry

Experiences in control of continuous and discontinuous polymerization processes did prove that process computers can successfully replace conventional control systems, yielding a better performance. It has also been shown that marked process improvements are possible by application of advanced control concepts such as multivariable control, adaptive control and dynamic optimization. Because of the complexity and size of new batch systems, computer control is widely accepted. Its ability to enforce on-off sequencing and continuous control on the batch process and its adaptation flexibility to all process needs ensures high production levels by minimizing labor cost and lost production on idle equipment.
