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.

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).

In general, the production process in all plants do not have single process or have only single unit operation separated from other process but they have several operation units. And due to the restriction of the environment, safety and operating condition, it is very necessary to have the control system to control the condition and compensate for any deviation occurred. The methyl amines process is a complex chemical process with reaction and separation sections connected by several recycle streams. There are three consecutive reversible reactions that produce three different chemical components. In this thesis, the plantwide control strategy is considered for the methyl amines process. Fixture point theorem is applied to the plantwide control structures design for selecting appropriated set of controlled variables. A commercial process simulation software achieves the dynamics simulation of this research, both of steady-state and dynamics conditions.

With resources at a premium, and ecological concerns paramount, the need for clean, efficient and low-cost processes is one of the most critical challenges facing chemical engineers. The ability to control these processes, optimizing one, two or several variables has the potential to make more substantial savings in time, money and resources than any other single factor. Building on the success of the previous editions, this new third edition of A Real-Time Approach to Process Control employs both real industry practice and process control education without the use of complex or highly mathematical techniques, providing a more practical and applied approach. Updated throughout, this edition: • Includes a brand new chapter on Model predictive Control (MPC) • Now includes wireless and web-based technologies • Covers bio-related systems • Details the new multivariable control measure developed by the authors • Includes PowerPoint slides and solutions to Workshop problems on the accompanying website: http://www.wiley.com/go/svrcek-real-time-3e From the reviews of previous editions: “Would appeal to practising engineers due to its “hands on” feel for the subject matter. But more importantly, the authors present these concepts as fundamentals of chemical engineering, in a way that is consistent with how professor teach at the universities.” –Chemical Engineering Process (CEP) “The book has been beautifully crafted” –Engineering Subject Centre “Provides a refreshing approach to the presentation of process analysis and control” –The Chemical Engineer
