To be an effective engineer in process automation requires knowledge of a range of disciplines: chemical engineering, instrumentation, electrical engineering, control theory, mathematics, computing and management.Other books in these areas are generic and few are oriented towards the needs of the chemical and process industry. Process Automation Handbook distills into a single coherent handbook all the essentials of process automation at a depth sufficient for most practical purposes. The knowledge needed to cope with the majority of process control and automation situations is focused on. In doing so, a number of balances have been struck between theory and practice, classical and modern, technology and technique, information and understanding. The reader is referred to more specialised texts after receiving a thorough grounding of each topic.Process Automation Handbook will be of value to engineers actively concerned with process control and automation in the chemical and process industries.
