Читать книгу Profit Maximization Techniques for Operating Chemical Plants - Sandip K. Lahiri - Страница 22

Often distillation columns cause a bottleneck to increase plant capacity. It is very important to understand the operation and capacity limits of distillation columns in commercial plants. Chapter 11 enlightens the reader about how to evaluate a feasible operating window by using a capacity diagram. Calculations based on the capacity diagram and the effect of different design and operating variables on the capacity diagram are explained in detail with example calculations. This chapter enlightens the reader about operating profile assessment, tower rating assessment, tower efficiency assessment, and hydraulic performance evaluations of running distillation columns. It also provides practical guidelines regarding what to look for in distillation column optimization in an industrial context and explains the whole concept with real‐life case studies.
