This text reviews the types, design and usage of control valves in the process industries. It also discusses factors such as sizing, materials construction, the type of chemical flowing through the valve and maintenance. Technologies that affect the usage of valves are also considered.

The rapid growth and expansion of the chemical process industry during the past century have been accompanied by a simultaneous rise in human health problems as well as material and property losses because of fires, explosions, hazardous and toxic spills, equipment failures, other accidents, and business interruptions. Concern over the potential consequences of emissions of harmful chemicals (along with catastrophic accidents) has sparked interest at both the industrial and regulatory levels in obtaining a better understanding of the potential for environmental health risks in chemical and related industries. This practical book presents and examines the environmental and health risk assessment calculations as they apply to various chemical process industries. Chemical Process Industries: Environmental and Health Risk Calculations can be used as a college text designed to provide new engineers and scientists some comprehension of the industries into which they may enter. It also serves as a useful reference for practitioners and will help them better understand the health risk aspects of various industrial operations. The chemical process industries employ mechanical, electrical, and civil engineers and a host of other scientists; these professions should also benefit from material in this book that applies to their fields of work.

Presenting efficient and effective methods for developing dynamic simulations of chemical processes, this reference illustrates the techniques and fundamentals to develop, design, and test plantwide regulatory control schemes with commercial dynamic simulation packages. It provides case studies analyzing a wide variety of systems-ranging from simpl

Computer simulation is the key to comprehending and controlling the full-scale industrial plant used in the chemical, oil, gas and electrical power industries. Simulation of Industrial Processes for Control Engineers shows how to use the laws of physics and chemistry to produce the equations to simulate dynamically all the most important unit operations found in process and power plant.The book explains how to model chemical reactors, nuclear reactors, distillation columns, boilers, deaerators, refrigeration vessels, storage vessels for liquids and gases, liquid and gas flow through pipes and pipe networks, liquid and gas flow through installed control valves, control valve dynamics (including nonlinear effects such as static friction), oil and gas pipelines, heat exchangers, steam and gas turbines, compressors and pumps, as well as process controllers (including three methods of integral desaturation). The phenomenon of markedly different time responses ("stiffness") is considered and various ways are presented to get around the potential problem of slow execution time. The book demonstrates how linearization may be used to give a diverse check on the correctness of the as-programmed model and explains how formal techniques of model validation may be used to produce a quantitative check on the simulation model's overall validity.The material is based on many years' experience of modelling and simulation in the chemical and power industries, supplemented in recent years by university teaching at the undergraduate and postgraduate level. Several important new results are presented. The depth is sufficient to allow real industrial problems to be solved, thus making the book attractive to engineers working in industry. But the book's step-by-step approach makes the text appropriate also for post-graduate students of control engineering and for undergraduate students in electrical, mechanical and chemical engineering who are studying process control in their second year or later.

Aims to increase awareness of the opportunities afforded by measurement instruments and final elements. This title shows how to get maximum benefit from the revolution in smart technologies. It builds an understanding of the fundamental aspects of measurements, measurement instruments, and final elements for applications in the process industry.

Combining their extensive knowledge of process control, the team of William Luyben and Michael Luyben has developed a book that thoroughly covers the area of process control. With concise coverage that is easily readable and condensed to only essential elements, Essentials of Process Control presents the areas of process control that all chemical engineers need to know. The book's practical engineering orientation offers many real industrial control examples and problems. The authors present the practical aspects of process control such as sizing control valves, tuning controllers, and developing control structures. Readers will find helpful features of the book to include practical identification methods, which allow them to obtain information to tune controllers more quickly. In addition, the book discusses plantwide control and the interactions between steady-state design and dynamic controllability.
