John Wiley & Sons Inc Guidelines for Engineering Design for Process
Book SynopsisThis updated version of one of the most popular and widely used CCPS books provides plant design engineers, facility operators, and safety professionals with key information on selected topics of interest. The book focuses on process safety issues in the design of chemical, petrochemical, and hydrocarbon processing facilities. It discusses how to select designs that can prevent or mitigate the release of flammable or toxic materials, which could lead to a fire, explosion, or environmental damage. Key areas to be enhanced in the new edition include inherently safer design, specifically concepts for design of inherently safer unit operations and Safety Instrumented Systems and Layer of Protection Analysis. This book also provides an extensive bibliography to related publications and topic-specific information, as well as key information on failure modes and potential design solutions.Trade Review“I highly recommend it to process design engineers, project engineers, facility operators, and process safety/loss prevention specialists who will find it very useful." (Process Safety Progress, 1 November 2012) “While detailed engineering designs are outside the scope of the book, the authors provide extensive references to assist designers who wish to go beyond safety philosophy to the specifics of a particular safety system design.” (Chemical Engineering Progress, 1 August 2012)Table of ContentsAcronyms and Abbreviations xv Glossary xxi Acknowledgments xxxiii Foreward xxxv Preface xxxvii 1.

John Wiley & Sons Inc Organosilicon Chemistry WileyInterscience
Book SynopsisA comprehensive, up-to-date reference to synthetic applications of organosilicon chemistry Organic, organometallic, and polymer chemistry as well as materials science all utilize silicon in various forms, yet there is little cross-fertilization of ideas and applications among the disciplines.Trade Review"...this book provides a good 'state-of-the-art' compilations and evaluation at the turn of the century. This work should be included in any chemistry reference collection." (Choice, Vol. 38, No. 8, April 2001) "This book was a pleasure to read. It is very well written in a relaxed chatty style that conveys the obvious deep interest and delight the author brings to the subject...the book can quite rightly claim to be the 'Eaborn' of the 2000s." (Journal of the American Chemical Society, Vol. 123, No. 5, November 2000) In recent years there have been several books published that describe the various topical uses of silicon in organic synthesis. All of these books have been useful, but they did not present the broader picture of how the chemistry of the element silicon has had a major impact on many technologies. The author refers to some earlier "classical" books on silicon chemistry, particularly Eaborn's text of the 1960s, that set a very high and comprehensive standard by which to be judged. Without a doubt, Michael Brook has met this standard. This book was a pleasure to read. It is very well written in a relaxed and chatty style that conveys the obvious deep interest and delight the author brings to the subject. There are an impressive number of references to substantiate this scholarly text. One minor point that might (subjectively) make the book even better would be to place Chapter 14 (Electronic Effects of Silyl Group) earlier since it so germane to all of the book. The price is high, but not unreasonably so, and the book can quite rightly claim to be the "Eaborn" of the 2000s. (Phillip Magnus, University of Texas at Austin) "...Brook discusses selected topics regarding synthesis he considers of most use to graduate students and practicing chemists." (SciTech Book News, Vol. 24, No. 4, December 2000) "...this is a completely successful book..."

John Wiley & Sons Inc Biodesulfurization in Petroleum Refining
Book SynopsisFrom basic tenets to the latest advances, this is the most comprehensive and up-to-date coverage of the process of biodesulfurization in the petroleum refining industry. Petroleum refining and process engineering is constantly changing. No new refineries are being built, but companies all over the world are still expanding or re-purposing huge percentages of their refineries every year, year after year. Rather than building entirely new plants, companies are spending billions of dollars in the research and development of new processes that can save time and money by being more efficient and environmentally safer. Biodesulfurization is one of those processes, and nowhere else it is covered more thoroughly or with more up-to-date research of the new advances than in this new volume from Wiley-Scrivener. Besides the obvious benefits to biodesulfurization, there are new regulations in place within the industry with which companies will, over the next decade or longeTable of ContentsPreface xiii 1

Book SynopsisA 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.

Book SynopsisThis book provides a comprehensive treatment of investing chemical processing incidents. It presents on-the-job information, techniques, and examples that support successful investigations. Issues related to identification and classification of incidents (including near misses), notifications and initial response, assignment of an investigation team, preservation and control of an incident scene, collecting and documenting evidence, interviewing witnesses, determining what happened, identifying root causes, developing recommendations, effectively implementing recommendation, communicating investigation findings, and improving the investigation process are addressed in the third edition. While the focus of the book is investigating process safety incidents the methodologies, tools, and techniques described can also be applied when investigating other types of events such as reliability, quality, occupational health, and safety incidents.Table of ContentsPreface xxv Acknowledgments xxvii Acronyms and Abbreviations xxix 1 Introduction 1 1.1 Building on the Past 1 1.2

John Wiley & Sons Inc A Polygeneration Process Concept for Hybrid Solar
Book SynopsisThis is the most comprehensive and in-depth study of the theory and practical applications of a new and groundbreaking method for the energy industry to go green with renewable and alternative energy sources. The global warming phenomenon as a significant sustainability issue is gaining worldwide support for development of renewable energy technologies. The term polygeneration is referred to as an energy supply system, which delivers more than one form of energy to the final user. For example, electricity, cooling and desalination can be delivered from a polygeneration process. The polygeneration process in a hybrid solar thermal power plant can deliver electricity with less impact on the environment compared to a conventional fossil fuel-based power generating system. It is also THE next generation energy production technique with the potential to overcome the undesirable intermittence of renewable energy systems. In this study, the polygeneration process simulTable of ContentsContents Foreword ix Preface xi 1. Introduction 1 1.1. Global Scenario on Renewable Energy 3 1.2.
