Accident Classified As: Reportable Quantity
On Sunday, April 14, 2013, at approximately 0843 hours, the flare gas management (FGM) compressors were shut down due to high molecular weight materials being purged to the system during the Alky Unit startup. Sulfur dioxide was released to the air.
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. The compressors were returned to service immediately after equipment preparation and maintenance activities were completed.
Emissions were minimized as much as possible and the FGM compressors were returned to normal operation as soon as possible. A similar event labeled "not preventable" occurred on March 2, 2013, LDEQ number: 147101.
