A mechanical engineer with a Pennsylvania turbomachinery company, A ungier describes his own system and strategy for designing and analyzing centrifugal compressor aerodynamics. To address the novice as well as the experienced in the field, he presents the basic thermodynamic and fluid dynamic principles, empirical models, and key numerical methods that form the basis of his methods. His strategy, or design practice, he found harder to describe because it involves a process of reasoning rather than following an established set of principles. He recognizes that his is only one of many possible methods, but makes no effort to compare or contrast his with any other.

Originating in the process compressor industry, this text primarily addresses: rotating equipment engineers, project engineers, engineering contractors, and compressor user companies in oil and gas field operations, natural gas processing, petroleum refining, petrochemical processing, industrial refrigeration, and chemical industries. It enables the reader to assess compressors and defines the constraints influencing the compressor design.

Surge Control of Active-magnetic-bearing-suspended Centrifugal Compressors sets out the fundamentals of integrating active magnetic bearing (AMB) rotor suspension technology in compressor systems, and describes how this relatively new bearing technology can be employed in active control of compressor surge initiation. The authors provide a self-contained and comprehensive review of rotordynamics and the fundamentals of AMB technology. The active stabilization of compressor surge employing AMBs in a machine is fully explored, from modeling of instability and controller design, to the implementation and experimental testing of the control algorithm in a specially-constructed, industrial-size centrifugal compression system. The results of these tests demonstrate the great potential of the new surge control method suggested in this text. This book will be useful for engineers in industries that involve turbocompressors and magnetic bearings, as well as for researchers and graduate students in the field of applied control. Whatever their level of experience, engineers working in the fields of turbomachinery, magnetic bearings, rotordynamics and controls will find the material in this book absorbing as all these important aspects of engineering are integrated to create a multi-disciplinary solution to a real-life industrial problem and the book is a suitable introduction to the area for newcomers.

A modern reference to the principles, operation, and applications of the most important compressor types Thoroughly addressing process-related information and a wider variety of the major compressor types of interest to process plants, Compressors and Modern Process Applications uniquely covers the systematic linkage of fluid processing machinery to the processes they serve. This book is a highly practical resource for professionals responsible for purchasing, servicing, or operating compressors. It describes the main features of over 300 petrochemical and refining schematics and associated process descriptions involving compressors and expanders in modern industry. The organized presentation of this reference covers first the basics of compressors and what they are, and then progresses to important operational and process issues. It then explains the underlying principles, operating modes, selection issues, and major hardware elements for compressors. Topics include double-acting positive displacement compressors, rotary positive displacement compressors, understanding centrifugal process gas compressors, power transmission and advanced bearing technology, centrifugal compressor performance, gas processing and turbo-expander applications, and compressors typically found in petroleum refining and other petrochemical processes. Suitable for plant operation personnel, machinery engineering specialists, process engineers,as well as undergraduate students of this subject, this book's special features include: * Flow schematics of modern process units and processes used in gas transport, gas conditioning, petrochemical manufacture, and petroleum refining * Listings of licensors for each process on the flow schematics * Identification of each process flow schematic of compressors, cryogenic, and hot gas expanders at their respective locations * Important overview of surge control, estimating compressor performance, applications for air separation and gas processing plants, petroleum refinery issues, and important criteria that govern compressor selection and application Placing hundreds of associated process flow schematics at the fingertips of professionals and students, author and industry expert Heinz Bloch facilitates comprehension of the workings of various petrochemical, oil refining, and product upgrading processes that are served by compressors.

This practical reference provides in-depth information required to understand and properly estimate compressor capabilities and to select the proper designs.
