Abstract: This paper deals with automation in industrial plants where batch processes are used, such as food, pharmaceutical and cement industries. Individual pieces of equipment in these plants are controlled by independent programmable logical controllers (PLC). PLC-s communicates with each other and synchronizes their work. With a well-designed automated system, the need for operators’ supervision is greatly minimized and hence permits the labor cost to be reduced and optimizing the repeatability and efficiency of the process done by the system. Thus, the operator may readily and efficiently take real time action on the flow of the process permitting the latter to have an upper hand on the system as the latter may decide his own desirable set points at critical intervals. Clean-in-plant (CIP) processes are time intensive and waste large amounts of energy, water, and chemicals. New innovations in CIP technology allow plant operators to cut costs in an earth-friendly manner while still conforming to regulatory safety standards. This paper explains how new CIP technologies can improve production efficiency.
