Cause of Problem: Under Investigation

On November 5, 2014 at approximately 04:25 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 not able to handle the excess gas and the flaring occurred intermittently for 364 minutes until K-8101 could be restarted. During this time, only one of the three flare gas compressor was available due to mechanical failures were down for repairs. With two flare gas compressors offline for repairs there was not sufficient capacity to recover all of the excess gas. An investigation into the root cause of the event is still ongoing and results will be provided in a 60-day follow up 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 immediately 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 fo the failure and preventability determinations. Results will be provided in a 60-day follow up letter.
