Dry gas seal issues in syngas compressors
Thread Content
What is the impact of a secondary inlet temperature of over 70 degrees Celsius in the syngas compressor on the dry gas seal?
The impact at 70 degrees should not be very significant
There is no impact; the dry gas seal can withstand temperatures of around 100°C during normal operation
We removed the dry gas seal and found carbon black; we’re not sure what caused this
Where is the carbon black located? The material of the dry-sealed stationary ring contains carbon!
Could it be that the isolation gas has failed and lubricant has entered the secondary seal?
Over 70 degrees, the oil will not form carbon deposits
