TANDEM DRY GAS SEALS – Design and Maintenance Considerations for Enhanced Reliability and Performance
Abstract
Dry Gas Seals have been in existence in the process centrifugal compressor industry for the last three decades and majority of the compressor units in operation today are installed with Dry Gas Seals. DGS sealing and the associated systems gained importance predominantly due to unreliability, high operating and maintenance costs and hazardous characteristics inherent with the conventional lubricated shaft sealing systems. This Technical Brief shall cover the best practices to improve dry gas seals reliability and performance including: ? Design and Maintenance considerations ? Major factors affecting Dry Gas seals life and efficient operation ? Seal Gas supply and control requirements ? Primary Gas seal venting and health monitoring ? Secondary Gas seal venting and health monitoring ? Separation gas supply and control requirements ? Recommended Alarm and Shutdown conditions
