  "id": "MLC-T-ENV-025163",
  "term": "Self-Contained Wet Seal Centrifugal Compressor",
  "field": "Environment",
  "definition": "(1) A wet seal centrifugal compressor system that is a closed process that ports the degassing emissions into the natural gas line at the compressor suction ( i.e., degassed emissions are recovered) or which has an intermediate closed process that degasses most of the gas entrained in the seal oil and sends that gas to another process. The de-gas emissions are routed back to suction or process directly from the closed or intermediate closed degassing process; after the closed or intermediate closed degassing process the oil is ultimately recycled for recirculation in the seals to the lube oil tank where any small amount of residual gas is released through a vent. (2) A wet seal centrifugal compressor equipped with mechanical wet seals, where (i) A differential pressure is maintained on the system and there is no off gassing of the lube oil, and (ii) The mechanical seal is integrated into the compressor housing.
