Читать книгу Profit Maximization Techniques for Operating Chemical Plants - Sandip K. Lahiri - Страница 25

All over the world, chemical plants are running 100–140% of their installed nameplate capacity. Profit maximization by capacity enhancement is a very common route in process industries. This high capacity running more than their design capacity is possible due to inherent safety margins available in process equipment. This chapter helps readers to understanding different safety margins available in process equipment and explains the strategy to exploit those margins. Chapter 14 explains in a systematic way how to increase plant capacity without affecting safety and reliability. Plant real bottlenecks and the potential opportunity to increase capacity can be evaluated by actually performing a demo test run of the plant with the highest possible capacity for one week, which is commonly known as a maximum capacity test run. Fourteen key steps to carry out a maximum capacity test run in commercial running plants is the key focus area of this chapter. All the steps of the maximum capacity test run are explained with real‐life examples and industrial case studies. The next step of the maximum capacity test run is to find real bottlenecks of the plant by a debottlenecking (DBN) study. How to carry out a DBN study from the existing data and its different aspects are discussed in this chapter.
