Accident Classified As: Reportable Quantity
Compressor went into high alarm for high vibration. It was determined that the vibration probe had provided a false alarm due to a faulty connection. Coker 2 Wet Gas Compressor K8101 went into alarm for high vibration on 12/18/2005.
Discharge not preventable. This release is not considered to be preventable at this time.
This is a letter rescining the notification made relative to Hydrogen Sulfide (H2S). Upon further review, the total amount of H2S is estimated to be less than the reportable quantity (RQ= 100 lbs). Chalmette refinery estimates that approximately 70 lbs of H2S was released to the atmosphere during the 12/18/05 event. In order to avoid equipment damage and associated emissions, refinery personnel shut down the machine in order to evaluate and develop a repair strategy. The vibration probe was repaired and the machine was put back in service, ending the incident. Instrument and electrical connections directly related to K8101 were double checked for proper connections in order to avoid a recurrence due to the same root cause. It was determined that the vibration probe had provided a false alarm due to a faulty connection. The vibration probe was repaired and the machine was put back in service, ending the incident. Instrument and electrical connections directly related to K8101 were double checked for proper connections in order to avoid a recurrence due to the same root cause. Although the facility claims that this was a false alarm, there must have been some type of equipment failure to result in the release of 26,127 lbs of sulfur dioxide. The incident released 26,127 lbs of S02, which exceeds the reportable quantity for S02 (RQ= 500 lbs).
