Carbon Seal - an overview | ScienceDirect Topics
The life of carbon seals (radial and face seal) is significantly reduced in dry gas applications where the N 2 dew points are below −30°C (−22°F). Lessons Learned. The use of 'bone dry' N 2 (dew points below −30°C) for intermediate and separation sealing duties has resulted in low seal MTBFs (below 12 months).
