This work covers reaction engineering (both chemical and biochemical), together with measurement and process control. In the new edition, the material on chemical reactor design has been re-arranged into four chapters. The first chapter covers general principles, the second, flow characteristics and modelling in reactors. Chapter 3 now includes material on catalytic reactions together with non-catalytic gas-solids reactions and chapter 4 covers other multiphase reactor systems. The chapter on biochemical engineering, has been completely re-written into two sections. The first deals with the nature of reaction processes controlled by micro-organisms and enzymes and is prefaced by background material on the relevant microbiology and biochemistry; and in the second section, the process engineering principles of biochemical reactors are discussed, and emphasis is given to those features which differentiate them from the chemical reactors described previously. A new chapter, "Measurement", describes the various in-line techniques for measurement of the process variables which constitute the essential inputs to the control system of the plant.
The chapters on the process control gives an updated treatment of the principles and applications of process control and concludes with a discussion of computer control of process plant.
