Cause of Problem: Under Investigation

On Wednesday, November 8, 2014, at approximately 13:27 hours the #2 Coker Wet Gas Compressor K-8101 tripped on an electrical outage and routed all gas to the flare gas recovery (FGR) system. The FGR system was unable to handle the excess gas and flaring occurred intermittently for 277 minutes until K-8101 could be restarted. Duration is listed as 4h 36m, however calculated duration from incident start time and incident end time is 11h 59m. An investigation into the root cause of the event is still ongoing and results will be provided in a 60-day followup letter.

Discharge Preventable - Under Investigation

Notes/Remedial Actions

#2 Coker rates were reduced to minimize the amount of excess gas being routed to the flare gas recovery system. An investigation into the cause of the trip started and was determined to be a tripped fuse. The fuse was replaced and the compressor was restarted as soon as possible. Chalmette refining is conducting a failure analysis of K-8101 to determine the cause of the failure and preventability determinations.
