Читать книгу Profit Maximization Techniques for Operating Chemical Plants - Sandip K. Lahiri - Страница 20

Today's complex chemical plants need advanced monitoring and control systems to quickly identify the suboptimal operation of process equipment and implement a quick optimization strategy. Running the plant at the highest possible capacity for profit maximization necessitates the development of an intelligent real‐time monitoring system. However, due to the large amount of process data, it is a herculean task to monitor each and every piece of process data. Chapter 9 enlightens the readers about an online intelligent monitoring system, KPI‐based process monitoring, a cause and effect‐based monitoring system, etc. It also gives an idea regarding the development of a potential opportunity‐based dashboard, loss and waste monitoring systems, a cost‐based monitoring system, a constraints‐based monitoring system, and how all these can be integrated into business intelligent dashboards.

In this chapter, a new advanced computational technique, namely principal component analysis (PCA), is discussed to visualize data. The advantage of such an online monitoring system is to visualize the plant condition from a higher level but with a lower dimension space. A step by step procedure to build a PCA‐based advance monitoring system is explained in detail, with examples and industrial case studies.
