Centrifugal Compressor Wet Seal Degassing Vent Emission

{
  "id": "MLC-T-ENV-004563",
  "term": "Centrifugal Compressor Wet Seal Degassing Vent Emission",
  "field": "Environment",
  "definition": "Emissions that occur when the high-pressure oil barriers for centrifugal compressors are depressurized to release absorbed natural gas or CO2. High-pressure oil is used as a barrier against escaping gas in centrifugal compressor shafts. Very little gas escapes through the oil barrier, but under high pressure, considerably more gas is absorbed by the oil. The seal oil is purged of the absorbed gas (using heaters, flash tanks, and degassing techniques) and recirculated. The separated gas is commonly vented to the atmosphere.",
