Accident Classified As: Below Reportable Quantity (BRQ)
On Wednesday, July 10, 2013, at approximately 0422 hours, the flare gas management (FGM) compressors began to lose suction intermittently due to mechanical issues. The root cause of the mechanical issues was determined to be residual high molecular wight material entrained in the flare gas compressor circulating water from the reported events on July 7, 2013. To mitigate long term issues, the circulating water was changed out in the system which resulted in the staging of the flare during the process.
CRLLC determined that changing the circulation water for the FGM compressors was the only option to bring the compressors back to stable operation.
Emissions were minimized as much as possible and the FGM compressors were returned to normal operation as soon as possible. To mitigate long term issues, the circulating water was changed out in the system which requires the staging of the flare during this process. CRLLC claimed that no reportable quantities were exceeded during this event although they did release over 500 pounds of sulfur dioxide which is RQ.
