Accident Classified As: No Information Given
On 7/6/05 Murphy Oil experienced a refinery-wide power interruption. During the shutdown and ensuing startup, the refinery experienced elevated sulfur dioxide and intermittent particulate emissions at the flares and the Sulfur Recovery Unit incinerator stacks. The power outage was apparently the result of high winds generated by Tropical Storm Cindy.
Immediate action was to safely get the units stabilized and try to avoid damage to equipment during the emergency shutdown. To ensure a safe restart, the refinery purged rich amine from #1 and #2 Amine units and the #2 Sour Water Stripper to the flares. The refinery minimized SO2 emissions during startup by having the #2 and #3 SRUs pre-heated prior to introduction of acid gas. Received two citizen complaints. Took steps to minimize emissions for the re start.
