CCPS Concept Book - Böcker

Written and edited by engineering contractors and industry project/maintenance managers as an easy-to-use guide for other industry professionals, this book identifies important process safety issues in the contractor-client relationship,which are not addressed by other groups and publications. While the issues may arise at any point in the life cycle of a plant, they should be resolved early in the relationship to permit a clearer focus on process safety issues. Topics covered are a general discussion of contractor safety programs; EPC (engineering, procurement, construction) contractual bases and work division as they address regulatory PSM issues; subcontractor relationships; and managing contractor-client risks.

A brief introduction to a complex topic, giving a description of the processes involved in an accidental or emergency release and the resulting downwind transport and dilution of gases, vapors, and aerosols.

This book documents CCPS's Aerosol Research Program to develop a model to predict liquid rainout from release of a pressurized, liquefied gas--and, hence the residual amount of material in a vapor cloud, which may be greater than the amount calculated from an enthalpy chart. RELEASE predicts the rate of fluid discharge, the depressurization, flashing and formation of liquid drops, the entrainment of drops into the vapor cloud, the subsequent spreading of the jet, and rate of liquid rainout to a pool on the ground. Designed in a modular fashion to permit adjustment and corrections as new data become available, its multi-layered approach contains sub-models that include the complexities of many variables, including the effect of liquid superheat, rate of bubble growth, criterion for bubble formation, and heat transfer from the liquid to the growing vapor bubble. To validate RELEASE, CCPS conducted small- and large-scale experiments using superheated water, heated liquefied chlorine, methylamine, and cyclohexane that produced valuable data in an area where data are scarce. This book gives complete access, in text and on CD-ROM, to the model and the test data, giving users an informed ability to apply the model to their own work.

Quantitative Risk Analysis is a powerful tool used to help manage risk and improve safety. When used appropriately, it provides a rational basis for evaluating process safety and comparing alternative safety improvements. This guide, an update of an earlier American Chemistry Council (ACC) publication utilizing the "hands-on" experience of CPI risk assessment practitioners and safety professionals involved with the CCPS and ACC, explains how managers and users can make better-informed decisions about QRA, and how plant engineers and process designers can better understand, interpret and use the results of a QRA in their plant.

At last, smaller chemical processing operations have truly easy access to process safety and risk management programs tailored to meet their needs. Written as a "how to" book with checklists, it offers sufficient information for managers of facilities with small chemical operations to implement a process safety program and meet existing regulations.

Members of the community who serve on LEPC’s are on the frontlines when it comes to responding effectively to incidents that may occur in local facilities handling hazardous materials. This book provides practical, solid information to assist them in formulating effective plans to respond to emergencies and reduce potential risks to the public.

This CCPS Concept book shows designers and operators of chemical facilities how to realistically estimate the flammable mass in a cloud of accidentally released material that is capable of igniting. It provides information on industry experience with flammable vapor clouds, basic concepts of fires and explosions, and an overview of related computer programs.

There are many different types of explosions, each with its own complex mechanism. Understanding explosions is important in preventing them. This reference provides valuable information on explosions for everyone involved in the operation, design, maintenance, and management of chemical processes, helping enhance understanding of the nature of explosions and the practical methods required to prevent them from occurring. The text includes: Fundamental basis for explosionsExplosive and flammable behavior and characteristics of materialsDifferent types of explosionsFire and explosion hazard recognitionPractical methods for preventing explosions or minimizing the potential consequencesAdditional referencesUnderstanding Explosions provides a practical understanding of explosion fundamentals, including the different types of explosions, the explosive and flammable behavior of materials, and the hazards related to fires and explosions. It also discusses practical methods to prevent and minimize the probability and consequence of an explosion during routine use of flammable, combustible and/or reactive materials.

Designed for chemical engineers and other technical personnel involved in the design, operation, and maintenance of facilities and equipment where deflagration and detonation flame arresters (DDFAs) may be required, this book fosters effective application and operation of DDFAs through treatment of their principles of operation, selection, installation, and maintenance methods. This reference covers a broad range of issues concerning DDAs, including: An overview of deflagration and detonation prevention and protection practicesAn overview of combustion and flame propagation and how DDAs halt propagationDeflagration and detonation flame arrester technologyInstallation in process systemsRegulations, codes, and standardsIllustrative examples, calculations, and guidelines for DDA selectionAppendices, including a glossary, a flame arrester specification sheet for vendor quotation, and a listing of flame arrester manufacturers.

Written by Laurence Britton, who has over 20 years' experience in the fields of static ignition and process fire and explosion hazards research, this resource addresses an area not extensively covered in process safety standards or literature: understanding and reducing potential hazards associated with static electricity. The book covers the nature of static electricity, characteristics and effective energies of different static resources, techniques for evaluating static electricity hazards, general bonding, grounding, and other techniques used to control static or prevent ignition, gases and liquids, powders and hybrid mixtures.

Layer of Protection Analysis: Simplified Process Risk AssessmentLayer of protection analysis (LOPA) is a recently developed, simplified method of risk assessment that provides the much-needed middle ground between a qualitative process hazard analysis and a traditional, expensive quantitative risk analysis. Beginning with an identified accident scenario, LOPA uses simplifying rules to evaluate initiating event frequency, independent layers of protection, and consequences to provide an order-of-magnitude estimate of risk. LOPA has also proven an excellent approach for determining the safety integrity level necessary for an instrumented safety system, an approach endorsed in instrument standards, such as ISA S84 and IEC 61511. Written by industry experts in LOPA, this pioneering book provides all the necessary information to undertake and complete a Layer of Protection Analysis during any stage in a processes' life cycle. Loaded with tables, charts, and examples, this book is invaluable to technical experts involved with ensuring the safety of a process. Because of its simplified, quicker risk assessment approach, LOPA is destined to become a widely used technique. Join other major companies and start your LOPA efforts now by purchasing this book.

A key component of risk reduction is reducing the potential consequences that could result from toxic or flammable releases. The science of vapor cloud dispersion has advanced significantly in recent years, but one of the long-standing challenges has been in accounting for dispersion around buildings, equipment, and similarly sized geologic and man-made features. With current concerns about terrorism in industrial and urban sites, improving consequence modeling within industrial and urban sites is more important than ever This new definitive book advances the science of vapor cloud dispersion by: ·Describing how structures at an urban or industrial site affect dispersion, and how these effects should be treated in consequence models ·Explaining surface roughness length (z0) and displacement length (d) so that they are clarified for readers with minimal meteorological background ·Presenting criteria for when the structures should be considered broadly as roughness elements, or when they should be considered from the viewpoint of their wake effects ·Defining conditions for which different models apply and providing continuous solutions for transitions between flow regimes. ·Providing the appropriate roughness inputs to transport and dispersion models depending on conditions. ·Demonstrating the application of these techniques through worked examples.
