Accident Classified As:
Booster blower motor failed to due to lubrication problem caused by rain getting inside it during a heavy storm--automatic oiler did not replenish oil that was drained off with the water afterward. Motor failure caused Tail Gas Treating Unit (TGTU) 4 to unexpectedly shut down and unit charge was diverted to the TGTU incinerator from the SRU (sulfur recovery unit); sour gas combustion then resulted in excess emissions. Exceeded RQ's. No DEQ report in this file--hazmat and follow-up only.
Made efforts to reduce operating rates on units producing acid gas or rich amine and to distribute the acid gas flow to other operating SRU/TGTUs. Installed motor from another piece of idled equipment in booster blower and restarted it.
