South Flare

Pollutant(s):
Sulfur Dioxide - 11,804 pounds
Sulfur Dioxide - 12,816 pounds
Sulfur Dioxide - 53 pounds
Sulfur Dioxide - 226 pounds
Particulate Matter - BRQ
Cause of Problem: Weather

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.

Cause of Problem: Equipment Failure

Power failure due to Entergy's loss of power
There are two state police numbers on this report thought only the 00969 one seems to be discussed. I have thus listed only that #. This is a follow up report for the power failure on 2/11. It does say smoke was intermittent, perhaps all releases were. The report also notes a re start date of 2/20 but there are no emissions listed for that date. The report on 4/4/05 details the emissions amounts for S02."
