Plant Optimization with Control Loop Performance Monitoring

-Metso PlantTriage-

Abstract

In recent years the plant operation with the small number of people is enabled mainly by the advancement of DCS, and the staff is reduced as a part of rationalization and the labor saving. In addition, the succession of the operation know-how of the plant becomes difficult for a similar reason. On the other hand, with complicated advancement of the plant control, the workload on operators and maintenance people are increasing. In such situation, it will be difficult to pay more attention to facilities improvement/the optimization of the plant.
In this paper, I would like to introduce“Metso PlantTriage”, the software which monitors performance of plant controls 24-7-365 and discovers the root cause of process problems with the case example at the bleaching plant where we successfully reduced the chemical consumption.
The word“Triage”used in the product name is the process of determining the priority of patients' treatments based on the severity of their condition in disaster medical care. This rations patient treatment efficiently when resources are insufficient for all to be treated immediately. In“PlantTriage”, we apply technique of the“Triage”to prioritize the problems which were found by 24-7-365 monitoring to optimize the plant in few resources effectively.
