Читать книгу Profit Maximization Techniques for Operating Chemical Plants - Sandip K. Lahiri - Страница 21

Chemical industries recently discovered that a large amount of profit becomes eroded due to unplanned shutdowns of the plant. Due to spurious trips of equipment much potential profit is lost. One major ingredients of profit maximization is to increase plant reliability and running hours. Plant shutdown can be avoided by building a robust fault diagnosis system that will detect and alert the operator about any potential event that can lead to plant disturbance and eventually plant shutdown before it starts happening. How a robust fault diagnosis system can be made by PCA and ANN that can be implemented in industry is discussed in detail in this chapter with industrial case studies. Different aspects of enhancement of plant reliability by an advance monitoring and fault diagnosis system is the main focus of the chapter.
