Achieve successful compressor startup by addressing dry-gas seal failure

Zardynezhad, S., Toyo Engineering Canada Ltd.

A common root cause for compressor failure during first startup is a failure of the dry-gas seal (DGS) system. To avoid failures of gas compressors, the project team and end users must understand the importance and significance of the DGS very early in the basic design phase.
