Achieve successful compressor startup by addressing dry-gas seal failure

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.

When a centrifugal gas compressor fails during startup in any hydrocarbon processing industry (HPI) project, there will be significant time and cost impacts. Why? Compressors are often the “heart” of the facility. A common root cause for compressor failure during first startup is a failure of the dry-gas seal (DGS) system. Replacement of compressor seals without understanding and analyzing the failure causes can lead to another failure. Due to the centrifugal gas compressor’s cost, size, and long delivery time, HPI plants normally do not have a standby compressor available. Therefore, any seal failure will result in plant downtime and lost production. To avoid failures of ga
