Accident Classified As:
Entergy experienced a ground fault and the backup supply failed to switch in a timely manner. Forced most process units to shutdown resulting in flaring and venting of CO. Two pressure valves relieved to the atmosphere.
With most of the process units down, there was isufficient feed to keep the SRU tail gas treater online. The tail gas from SRU 591 was routed directly to the SRU incinerator until other refinery process units restarted to provide sufficient feed to support stable TGT operation. There was some smoking form the flares.
