| Review: |
Dry gas seals operate at high speeds and pressures at a relatively tiny clearance and gas leakage rate. As these seals achieve faster run time in the field, the operating envelope is continually being redefined; they can currently run at sealing pressures above 6000 psi and clearance measured in microns. This book is a practical guide to gas seal technology and its practical application in process gas centrifugal compressors. It gives a complete guide to the technology, from the principle of gas seal operation, to lessons learned from field experience. There are chapters on dry gas seals, dry gas seal configurations, barrier seals, dry gas seal support systems, dry gas seal retrofits, operation and maintenance, and contamination. |
