Process Automation Handbook (eBook)

This book distils into a single coherent handbook all the essentials of process automation at a depth sufficient for most practical purposes. The handbook focuses on the knowledge needed to cope with the vast majority of process control and automation situations. In doing so, a number of sensible balances have been carefully struck between breadth and depth, theory and practice, classical and modern, technology and technique, information and understanding. A thorough grounding is provided for every topic. No other book covers the gap between the theory and practice of control systems so comprehensively and at a level suitable for practicing engineers.

Jonathan Love has a variety of experience and expertise in the analysis, design, development and operation of instrumentation and control systems as used for the automation of plant in the chemical, process and oil industries. His early academic career involved lectureships at Huddersfield, Leeds and Sheffield Universities. He is currently in the School of Chemical Engineering and Advanced Materials at Newcastle University where he is Director of the Integrated Graduate Development Scheme (IGDS) in Process Automation. His industrial experience consists of periods working as a commissioning engineer for Akzo Nobel (formerly Courtaulds Ltd) and as a control engineer for Honeywell Process Solutions (formerly KBC Process Automation). He is currently Principal Automation Consultant for BP Exploration and Production.

These include globali- tion, increased earning per share expectation, increasing safety and environmental legislation, staff retirement, shortage of engineers and increasingly rapid evolution of technology. To be successful, process manufacturing companies must respond by: Consistently improving safety and environmental performance Becoming more responsive to customers Reducing manufacturing costs Reducing working capital Improving equipment life There are many approaches to achieving these improvements such as improvement of process equipment and ?owsheets, staff training, work process improvement, organizational restructuring and, in particular, process automation.
