The use of control systems is necessary for safe and optimal operation of industrial processes in the presence of inevitable disturbances and uncertainties. Plant-wide control (PWC) involves the systems and strategies required to control an entire chemical plant consisting of many interacting unit operations. Over the past 30 years, many tools and methodologies have been developed to accommodate increasingly larger and more complex plants. This book provides a state-of-the-art of techniques for the design and evaluation of PWC systems. Various applications taken from chemical, petrochemical, biofuels and mineral processing industries are used to illustrate the use of these approaches. This book contains 20 chapters organized in the following sections: Overview and Industrial Perspective Tools and Heuristics Methodologies Applications Emerging Topics With contributions from the leading researchers and industrial practitioners on PWC design, this book is key reading for researchers, postgraduate students, and process control engineers interested in PWC.

The first book to offer a practical, plantwide approach to designing effective controls for continuous chemical and petroleum processes Process control lore includes tales of multi-million dollar plants that never operated. Though individual controls were well designed, they simply did not work together. This book the first to offer a practical, plantwide approach to preventing such catastrophes. Written by three respected experts and verified in real-life implementations, this book helps you develop effective basic regulator control systems for plants on the drawing board, being revamped, or in full operation. Four realistic case studies (Tennessee-Eastman, isomerization, vinyl acetate, and HDA processes) contribute to making this guide a process control classic.

The complete control system engineering solution for continuous and batch manufacturing plants. This book presents a complete methodology of control system design for continuous and batch manufacturing in such diverse areas as pulp and paper, petrochemical, chemical, food, pharmaceutical, and biochemical production. Geared to practicing engineers faced with designing increasingly more sophisticated control systems in response to present-day economic and regulatory pressures, Plantwide Process Control focuses on the engineering portion of a plant automation improvement project. It features a full control design information package (Control Requirements Definition or CRD), and guides readers through all steps of the automation process-from the initial concept to design, simulation, testing, implementation, and operation. This unique and practical resource: * Integrates continuous, batch, and discrete control techniques. * Shows how to use the methodology with any automation project-existing or new, simple or complex, large or small. * Relates recent ISO and ISA standards to the discipline of control engineering. * Illustrates the methodology with a pulp-and-paper mill case study. * Incorporates numerous other examples, from single-loop controllers to multivariable controllers.

Presenting efficient and effective methods for developing dynamic simulations of chemical processes, this reference illustrates the techniques and fundamentals to develop, design, and test plantwide regulatory control schemes with commercial dynamic simulation packages. It provides case studies analyzing a wide variety of systems–ranging from simple units to complex interacting unit operations. The book offers strategies to move from steady-state simulations to dynamic simulations, install and tune controllers, size control valves and equipment, and add strip-chart recorders to simulations. It also provides access to website downloads of applications in HYSYS and AspenDynamics.

In this work, plantwide control structure design procedure of Wongsri (2012) is presented and applied to the monoisopropylamine process. The plant consists of a tubular reactor and three distillation columns. There are two recycle streams: gas and liquid. The raw materials are isopropyl alcohol and ammonia which are converted to MIPA, DIPA, and water. The by-product DIPA is recycled to react with ammonia to form MIPA. An excess of ammonia in the reactor inhibits the DIPA reaction, so ammonia is also recycled. The plant with control structure designed called the fixture plant. The raw materials entered the process is fixed and the products are regulated according to their accumulation. The recycle flowrate of DIPA is adjusted by its quantifier. The temperature loops are designed to reject the thermal disturbance. The first distillation column is controlled using a single temperature and a reflux-to-feed ratio control structure. The second distillation column is controlled using a single temperature and either a reflux-to-feed ratio or reflux ratio control structure. The third column has three alterative control structures which are the same as the second column and dual control structure ratio (one temperature and one composition).
