Dry Gas Seals Handbook

Description

Despite the fact that the use of dry gas seals in process gas centrifugal compressors has increased dramatically over the last 20 years, the technology remains misunderstood by many in the industry. Dry gas seals operate with clearances measured in microns, much less than the thickness of a human hair. While dry gas seals can be very problematic if not properly applied at the time of plant, process, and/or compressor design, the many successful installations are a testament to how trouble-free these devices can be when properly applied. Dry gas seals are in used in compressor stations, processing plants, refineries, chemical plants, and more. The information found in this Handbook will help to make informed decisions regarding the application, operation, and maintenance of dry gas seals. Suited for engineers, operators, maintenance personnel, purchasing personnel and technical management, this book presents a complete guide to the technology, from the principle of gas seal operation to “lessons learned” from actual field experience.
