This book gives a practical in-depth account of the concept of control valve sizing and selection. It explains the underlying issues that must be considered and the factors involved. It unmasks the mystery surrounding these factors and clarifies the relationships and interactions between them. The book analyses the roles of these factors, and explains how the control valve behavior changes and its characteristics modified under the varying process conditions so that a prediction of valve behavior can be made prior to selection. The boo provides guidelines and rules of thumb for valve sizing and selection.

Control valves are imperative elements in any system where fluid flow must be monitored and manipulated. A complete control valve is made of the valve itself, an actuator, and, if necessary, a valve control device. The actuator is what provides the required force to cause the closing part of the valve to move and the valve control devices keep the valves in the proper operating conditions; they can ensure appropriate position, interpret signals, and manipulate responses.Selection of the proper valve involves a thorough knowledge of the process for which it will be used. When implementing a control valve into a process, one must consider not only the appropriate type of valve and its material of construction, but also the correct sizing to ensure it performs its designated task without any adverse occurrences in the system.This 4-hour quick book provides an overview of control valve with emphasis on the sizing and selection. This course is for mechanical, instrumentation and process engineers involved in sizing, selecting and applying process control valves. No specific prerequisite training or experience is required.Learning ObjectiveAt the conclusion of this course, the reader will:• Differentiate between various types of valves and the benefits of each;• Understand the operation of control valve in a control loop;• Understand how to evaluate and apply actuators and positioners for specific applications;• Understand the basic hydraulics and the relationship between the Cv, flow rate and pressure drop;• Understand how to size valves for any flow condition likely to be found in a process plant;• Understand how to select the proper valve characteristic for a given process;• Understand how the installed characteristics can match closely to the inherent characteristics;• Understand the methods to address system performance issues such as cavitation, flashing and chocked conditions;• Understand the factors influencing the selection of control valves.

This up-to-date work on final control elements presents theoretical and practical information in an easy, conversational style, which makes it an excellent reference for experienced instrument and process engineers as well as students who are new to the field. The book begins with a basic explanation of the function and purpose of control valves, explaining the various types of valves that are available along with their features and limitations. It also provides: * Directions for selecting the best valve for a given service and the right flow characteristics * Simplified equations for sizing control valves for liquids and gases under normal and special conditions, such as flashing and laminar flow * Directions for minimizing environmental problems, such as noise produced by turbulent or cavitating fluids and aerodynamic noise * Solutions to dynamic instability problems * Methods for improving control loop stability * Discussion on related safety issues such as "fail-safe" action and cybersecurity Many reference tables provide information that will be invaluable in valve selection, such as valve materials, temperature ratings, and valve dimensions. Also, for the benefit of international readers, examples and equations are presented in metric as well as U.S. customary terms and measurements.

were published in the series as the contributed volume, Process Control Performance Assessment: From Theory to Implementation with Andrzej Ordys, Damian Uduehi, and Michael Johnson as Editors (ISBN 978-1-84628-623-0, 2007). Along with this good progress in process controller assessment methods, researchers have also been investigating techniques to diagnose what is causing the process or control loop degradation. This requires the use of on-line data to identify faults via new diagnostic indicators of typical process problems. A significant focus of some of this research has been the issue of valve problems; a research direction that has been motivated by some industrial statistics that show up to 40% of control loops having performance degradation attributable to valve problems. Shoukat Choudhury, Sirish Shah, and Nina Thornhill have been very active in this research field for a number of years and have written a coherent and consistent presentation of their many research results as this monograph, Diagnosis of Process Nonlinearities and Valve Stiction. The Advances in Industrial Control series is pleased to welcome this new and substantial contribution to the process diagnostic literature. The reader will find the exploitation of the extensive process data archives created by today’s process computer systems one theme in the monograph. From another viewpoint, the use of higher-order statistics could be considered to provide a continuing link to the earlier methods of the statistical process control paradigm.

A guide to all practical aspects of building, implementing, managing, and maintaining MPC applications in industrial plants Multivariable Predictive Control: Applications in Industry provides engineers with a thorough understanding of all practical aspects of multivariate predictive control (MPC) applications, as well as expert guidance on how to derive maximum benefit from those systems. Short on theory and long on step-by-step information, it covers everything plant process engineers and control engineers need to know about building, deploying, and managing MPC applications in their companies. MPC has more than proven itself to be one the most important tools for optimising plant operations on an ongoing basis. Companies, worldwide, across a range of industries are successfully using MPC systems to optimise materials and utility consumption, reduce waste, minimise pollution, and maximise production. Unfortunately, due in part to the lack of practical references, plant engineers are often at a loss as to how to manage and maintain MPC systems once the applications have been installed and the consultants and vendors’ reps have left the plant. Written by a chemical engineer with two decades of experience in operations and technical services at petrochemical companies, this book fills that regrettable gap in the professional literature. Provides a cost-benefit analysis of typical MPC projects and reviews commercially available MPC software packages Details software implementation steps, as well as techniques for successfully evaluating and monitoring software performance once it has been installed Features case studies and real-world examples from industries, worldwide, illustrating the advantages and common pitfalls of MPC systems Describes MPC application failures in an array of companies, exposes the root causes of those failures, and offers proven safeguards and corrective measures for avoiding similar failures Multivariable Predictive Control: Applications in Industry is an indispensable resource for plant process engineers and control engineers working in chemical plants, petrochemical companies, and oil refineries in which MPC systems already are operational, or where MPC implementations are being considering.
