Plantwide Control


Book Description

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.




Chemical Engineering Dynamics


Book Description

In this book, the modelling of dynamic chemical engineering processes is presented in a highly understandable way using the unique combination of simplified fundamental theory and direct hands-on computer simulation. The mathematics is kept to a minimum, and yet the nearly 100 examples supplied on www.wiley-vch.de illustrate almost every aspect of chemical engineering science. Each example is described in detail, including the model equations. They are written in the modern user-friendly simulation language Berkeley Madonna, which can be run on both Windows PC and Power-Macintosh computers. Madonna solves models comprising many ordinary differential equations using very simple programming, including arrays. It is so powerful that the model parameters may be defined as "sliders", which allow the effect of their change on the model behavior to be seen almost immediately. Data may be included for curve fitting, and sensitivity or multiple runs may be performed. The results can be seen simultaneously on multiple-graph windows or by using overlays. The resultant learning effect of this is tremendous. The examples can be varied to fit any real situation, and the suggested exercises provide practical guidance. The extensive experience of the authors, both in university teaching and international courses, is reflected in this well-balanced presentation, which is suitable for the teacher, the student, the chemist or the engineer. This book provides a greater understanding of the formulation and use of mass and energy balances for chemical engineering, in a most stimulating manner. This book is a third edition, which also includes biological, environmental and food process examples.

A Real-Time Approach to Process Control


Book Description

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




Process Plant Design


Book Description

Process Plant Design An introductory practical guide to process plant design for students of chemical engineering and practicing chemical engineers. Process Plant Design provides an introductory practical guide to the subject for undergraduate and postgraduate students of chemical engineering, and practicing chemical engineers. Process Plant Design starts by presenting general background from the early stages of chemical process projects and moves on to deal with the infrastructure required to support the operation of process plants. The reliability, maintainability and availability issues addressed in the text are important for process safety, and the avoidance of high maintenance costs, adverse environmental impact, and unnecessary process breakdowns that might prevent production targets being achieved. A practical approach is presented for the systematic synthesis of process control schemes, which has traditionally received little attention, especially when considering overall process control systems. The development of preliminary piping and instrumentation diagrams (P&IDs) is addressed, which are key documents in process engineering. A guide is presented for the choice of materials of construction, which affects resistance to corrosion, mechanical design and the capital cost of equipment. Whilst the final mechanical design of vessels and equipment is normally carried out by specialist mechanical engineers, it is still necessary for process designers to have an understanding of mechanical design for a variety of reasons. Finally, Process Plant Design considers layout, which has important implications for safety, environmental impact, and capital and operating costs. To aid reader comprehension, Process Plant Design features worked examples throughout the text. Process Plant Design is a valuable resource on the subject for advanced undergraduate and postgraduate students of chemical engineering, as well as practicing chemical engineers working in process design. The text is also useful for industrial disciplines related to chemical engineering working on the design of chemical processes.
