Coordination of Process Areas

To achieve best overall plant operation, it is often necessary to coordinate the operation of equipment in multiple process areas. In Chapter 16 of Control Loop Foundation – Batch and Continuous Processes, several process examples are shown to demonstrate how multi-loop techniques may be effectively used for such coordination. One of these examples is ammonia …
