Vacuum systems are in wide spread use in the petrochemical plants, petroleum refineries and power generation plants. The existing texts on this subject are theoretical in nature and only deal with how the equipment functions when in good mechanical conditions, from the viewpoint of the equipment vendor. Also, the existing texts fail to consider the interaction of the vacuum system with the process equipment it serves and the variability of the motive steam conditions, change in cooling water temperature condenser fouling and erosion of the ejectors. Here are some of the many questions answered in this groundbreaking volume: Why does my first stage jet make a surging sound during hot weather? Why does the vacuum suddenly break? I've seen moisture condensing on the jet's body! What’s causing that? Why do I have to steam-out the drain legs from our condensers? Superheated steam is making our vacuum worse. Is this normal? How can I locate and measure air leaks? Reducing the steam pressure to my jets improves vacuum. But why? I can't pull the pre-condenser bundle. The shell side is fouling. What should I do? We're not getting our normal horsepower from our steam turbine. Could this be a jet problem? Raising the seal drum level improves vacuum! Is there an explanation for this? Our turbine exhaust steam pressure to our surface condenser has doubled in the last two years. What should we do? Restricting cooling water flow from our elevated condensers improves vacuum! Is this possible? What's a converging-diverging ejector all about? What's the difference between a barometric condenser and a surface condenser? Which is better?

A USERS GUIDE TO VACUUM TECHNOLOGY Choose and understand the vacuum technology that fits your project’s needs with this indispensable guide Vacuum technology is used to provide process environments for other kinds of engineering technology, making it an unsung cornerstone of hundreds of projects incorporating analysis, research and development, manufacturing, and more. Since it is very often a secondary technology, users primarily interested in processes incorporating it will frequently only encounter vacuum technology when purchasing or troubleshooting. There is an urgent need for a guide to vacuum technology made with these users in mind. For decades, A User’s Guide to Vacuum Technology has met this need, with a user-focused introduction to vacuum technology as it is incorporated into semiconductor, optics, solar sell, and other engineering processes. With an emphasis on otherwise neglected subjects and on accessibility to the secondary user of vacuum technology, it balances treatment of older systems that are still in use with a survey of the latest cutting-edge technologies. The result promises to continue as the essential guide to vacuum systems. Readers of the fourth edition of A User’s Guide to Vacuum Technology will also find: Expanded treatment of gauges, pumps, materials, systems, and best??operating practices Detailed discussion of cutting-edge topics like ultraclean vacuum and contamination control An authorial team with decades of combined research and engineering experience A User’s Guide to Vacuum Technology is essential for those entering emerging STEM programs, engineering professionals and graduate students working with a huge range of engineering technologies.

"This book approaches vacuum systems from a pressure regime viewpoint, covering basic vacuum science, followed by the rough vacuum regime, including gas load, pumping mechanisms, pressure measurement, vacuum system construction, and basic troubleshooting concepts. The study of high vacuum systems follows and the same topics are revisited, and finally the topics of leak detection and residual gas analysis are discussed."--Publisher.

Vacuum technology is widely used in many manufacturing and developmental processes and its applications grow in scope and sophistication. It is an inter-disciplinary subject, embracing aspects of mechanical, electrical and chemical engineering, chemistry, and materials science while having a broad foundation in physics. In spite of its technological importance, and perhaps because of its cross-disciplinary nature, substantial teaching and training is not widely available. Basic Vacuum Technology aims to give readers a firm foundation of fundamental knowledge about the subject and the ability to apply it. This book is an introductory text on how to use vacuum techniques. It provides a good grounding in the basic scientific principles and concepts that underlie the production and measurement of vacua. The authors describe how these are applied in representative low, medium, high, and ultra-high vacuum systems and explain the most important practical aspects of the operation of a large variety of pumps, components, and measuring instrumentation. The book introduces numerical methods for analysis and prediction of the behavior of vacuum systems in terms of the properties of their individual elements and enables readers to recognize and resolve problems with malfunctioning systems.
