Accident Classified As: Reportable Quantity
On Friday, April 26, 2013, at approximately 14:33 hours, the flare gas management (FGM) compressors stopped pumping during the startup of the fluidized catalytic cracking (FCC) unit due to high molecular weight in the system. The FGM compressors are not able to pump correctly with high molecular weight in the water interface. There was also the potential to cause long-term damage if the FGM compressors continued to be used during this process which would result in the recovery system being out of service for an extended period of time.

There was also the potential to cause long-term damage if the FGM compressors continued to be used during this process which would result in the recovery system being out of service for an extended period of time. The compressors were returned to service when equipment preparation and maintenance activities were completed.
The compressors were returned to service after equipment preparation and maintenance activities were completed on April 27, 2013 at 15:49 hours. All efforts were taken to minimize emissions as much as possible during the compressor outages. Community monitoring was conducted during the events and all results were non-detect. Steps were taken to minimize emissions as much as possible and operations are being adjusted to return the FGM compressors to normal operation.
