Classifying Explosion Prone Areas for the Petroleum, Chemical and Related Industries

 

William Andrew Publishing, 1995.

ISBNs 9780815513667

Colección: ScienceDirect

Resumen (en inglés): The degree of danger in the atmosphere of a hazardous location needs to be determined prior to selecting an acceptable electrical equipment installation. If maximum safety is the predominant factor in determining the type of electrical installations, the cost of electrical equipment will be extremely high. If low cost of electrical installation is the predominant factor, safety to personnel and equipment may be unacceptably low. It is, therefore, necessary to find a point of balance at which the cost and safety requirements are both satisfied and acceptable.

In nine out of ten cases, a hazardous location is classified much too conservatively. The reason for this conservative approach is a lack of knowledge and a misunderstanding of the actual concept of safety and danger. This book provides an in-depth understanding of the factors that influence the classification of a hazardous location. One factor, in combination with one or more other factors, will have an impact on the level of danger and its hazardous boundaries. These factors and their influences are explained in detail, and once their impact is understood, the classification of a hazardous location becomes a straightforward procedure.

Cleaning with Solvents

Methods and Machinery

 

William Andrew Publishing, 2014.

ISBNs 9780323225205

Colección: ScienceDirect

Resumen (en inglés):

High-precision cleaning is required across many sectors, including aerospace, defense, medical device manufacturing, pharmaceutical processing, semiconductor/electronics, and more. In this comprehensive reference work, solvent cleaning equipment is thoroughly covered with a focus on the engineering details of its operation and selection. Key data is provided alongside practical guidance, giving scientists and engineers in multiple sectors the information they need not only to choose the correct machine in the first place, but also how to operate it effectively and efficiently.

Low emission open-top vapor degreasers, enclosed machines of the vacuum and pressurized type, cosolvent machines, and adsorption of "tailpipe emissions" are covered in detail and fully illustrated in color. This unique book covers material known by designers and manufacturers of solvent cleaning machines, but not collected and organized for the benefit of users.

The comprehensive coverage provided by John Durkee makes this book relevant and timely not only for readers who wish to know more about how solvent cleaning equipment works but also those who are under pressure from environmental regulators or corporate management to find effective alternatives and those engaged in non-solvent cleaning operations who are unsatisfied with their cleaning results.

  • Clear, straightforward explanations of how various types of cleaning solvents should be managed to clean parts
  • Full-color, hand-drawn illustrations and photographs of the important internal sections of solvent cleaning machines
  • Design calculations of operating parameters in solvent cleaning machines

Cleaning with Solvents

Science and Technology

 

William Andrew Publishing, 2014.

ISBNs 9781455731312

Colección: ScienceDirect

Resumen (en inglés):

High-precision cleaning is required across a wide range of sectors, including aerospace, defense, medical device manufacturing, pharmaceutical processing, semiconductor/electronics, etc.

Cleaning parts and surfaces with solvents is simple, effective and low-cost. Although health and safety and environmental concerns come into play with the use of solvents, this book explores how safe and compliant solvent-based cleaning techniques can be implemented. A key to this is the selection of the right solvent. The author also examines a range of newer "green" solvent cleaning options.

This book supplies scientific fundamentals and practical guidance supported by real-world examples. Durkee explains the three principal methods of solvent selection: matching of solubility parameters, reduction of potential for smog formation, and matching of physical properties. He also provides guidance on the safe use of aerosols, wipe-cleaning techniques, solvent stabilization, economics, and many other topics.

A compendium of blend rules is included, covering the physical, chemical, and environmental properties of solvents.

  • Three methods explained in detail for substitution of suitable solvents for those unsuitable for any reason: toxic solvents don't have to be tolerated; this volume explains how to do better
  • Enables users to make informed judgments about their selection of cleaning solvents for specific applications, including solvent replacement decisions
  • Explains how to plan and implement solvent cleaning systems that are effective, economical and compliant with regulations

Co2 Lasers Effects and Applications

 

Academic Press, 1976.

ISBNs 9780122233500

Colección: ScienceDirect

Resumen (en inglés): CO2 Lasers: Effects and Applications examines and summarizes the important applications of the device in different areas of study like physics, chemistry, and engineering. In some parts of the book, the reader is assumed to be knowledgeable in university level mathematics or some specialized area in physics or chemistry.
The book consists of 10 chapters where the first two establish the general concepts on lasers and CO2 lasers, respectively. Chapter 3 takes the reader further and presents a comprehensive review of optical components for use such as detectors, windows, and mirrors. Because the CO2 laser is mostly used as a heat source, the theory of laser-surface heating is relevant in the discussion. This theory is presented in Chapter 4. Chapters 5 and 6 meanwhile present a summary of observations on cutting, welding, and some related topics. The following chapters discuss the different applications of CO2 lasers in different areas and processes. Some of these applications include in the generation of thermal effect, laser deposition of thin films, spectroscopy, laser photochemistry, and meteorology and communication systems.
The text is a good source of reference to both students and scientists in the areas of physics, chemistry, and engineering.

Computational Materials Engineering

Achieving High Accuracy and Efficiency in Metals Processing Simulations

 

Butterworth-Heinemann, 2016.

ISBNs 9780124167070

Colección: ScienceDirect

Resumen (en inglés):

Computational Materials Engineering: Achieving High Accuracy and Efficiency in Metals Processing Simulations describes the most common computer modeling and simulation techniques used in metals processing, from so-called "fast" models to more advanced multiscale models, also evaluating possible methods for improving computational accuracy and efficiency.

Beginning with a discussion of conventional fast models like internal variable models for flow stress and microstructure evolution, the book moves on to advanced multiscale models, such as the CAFÉ method, which give insights into the phenomena occurring in materials in lower dimensional scales.

The book then delves into the various methods that have been developed to deal with problems, including long computing times, lack of proof of the uniqueness of the solution, difficulties with convergence of numerical procedures, local minima in the objective function, and ill-posed problems. It then concludes with suggestions on how to improve accuracy and efficiency in computational materials modeling, and a best practices guide for selecting the best model for a particular application.

  • Presents the numerical approaches for high-accuracy calculations
  • Provides researchers with essential information on the methods capable of exact representation of microstructure morphology
  • Helpful to those working on model classification, computing costs, heterogeneous hardware, modeling efficiency, numerical algorithms, metamodeling, sensitivity analysis, inverse method, clusters, heterogeneous architectures, grid environments, finite element, flow stress, internal variable method, microstructure evolution, and more
  • Discusses several techniques to overcome modeling and simulation limitations, including distributed computing methods, (hyper) reduced-order-modeling techniques, regularization, statistical representation of material microstructure, and the Gaussian process
  • Covers both software and hardware capabilities in the area of improved computer efficiency and reduction of computing time
