Accident Classified As: Reportable Quantity
There was sudden unexpected loss of O2 supply from Air Products causing SRU1 to immediately shut down. Acid gas (SO2 and H2S) was released intermittently through Number 1 Flare. SRU 1 was sole operating SRU at the time of incident, as SRU 2 was shutdown for maintenance.
Refinery letter states that incident was not preventable as loss of Air Products oxygen was unforeseeable. LDEQ report states that "Lack of co-ordination during maintenance activities ultimately resulted in this flaring event. This is considered clareless and/or improper operation, i.e. PREVENTABLE, as will be referred to AOC with LAC 33:III.905.A."
Steam controllers have been repaired and rebuilt. There was also an evaluation of alarm changes to provide more response time. EPA Acid Gas Flaring report included. LDEQ conducted an investigation in response to this incident on 12/8/11.
