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. Let author John Stahley help you take the mystery out of dry gas seals in this comprehensive new book. Dry gas seals are in used in compressor stations, processing plants, refineries, chemical plants, and more.
