Opis

Offering a modern, process-oriented approach emphasizing process control scheme development instead of extended coverage of LaPlace space descriptions of process dynamics, Designing Controls for the Process Industries focuses on aspects that are most important for contemporary practical process engineering and reflects the industry’s use of digital distributed control-based systems. The new edition now features dozens of tutorial videos showing solutions to most of the example problems.

Instead of starting with the controller, the book starts with the process and moves on to how basic regulatory control schemes can be designed to achieve the process objectives while maintaining stable operations. In addition to continuous control concepts, process and control system dynamics are embedded into the text with each new concept presented. The book also includes sections on batch and semi-batch processes and safety automation within each concept area. It discusses the four most common process control loop feedback, feedforward, ratio, and cascade and discusses application of these techniques for process control schemes for the most common types of unit operations. It also discusses more advanced and less commonly used regulatory control options such as override, allocation, and split range controllers, includes an introduction to higher level automation functions, and provides guidance for ways to increase the overall safety, stability, and efficiency for many process applications. It introduces the theory behind the most common types of controllers used in the process industries and also provides various additional plant automation-related subjects. The new edition also includes new homework problems and examples, information about statistical process control, and a new case study that documents the development of regulatory control schemes for an entire process area.

Aimed at chemical engineering students in process control courses, this textbook offers an alternative to traditional texts and offers a practical, hand-on approach to design of process controls.

PowerPoint slides for each chapter, multiple choice questions for flipped classes, and a solutions manual are available to qualifying instructors.
