FLARE - FCCU flare
Cause: "Loss of power in Complex II caused operating and utility units to shutdown. This even resulted in flaring from the FCCU flare" Due to the loss of power, the complex II steam producers shut down, therefore the flare steam assist was lost. This resulted in smoking flares. This released the following chemicals: SO2, H2S, NOx, VOC, Hexane, and 1,3 Butadiene. FLARE.

Followup: No

Notes: A power feed was connected from Complex I to Complex II, and boilers were restarted to produce steam to assist the FCCU flare, and shutdown procedures was continued. No LDEQ report. Refinery Letter only.
Sulfur Dioxide: 110.6 pounds
Hydrogen Sulfide: 2.9 pounds
Nitric Oxide: 14.9 pounds
Volatile Organic Compounds (VOCs): 663.2 pounds
Carbon Monoxide: 109.9 pounds
1,3-Butadiene: 4.1 pounds

Complex 1 & 2 Flares, FCCU Stack
Complex 2 Flare
Cause: On July 15, 2013 at approximately 12:28 pm, Alon Refining Krotz Springs (ARKS) suffered a facility-wide power loss. This power loss caused a facility-wide emergency shutdown. Due to the emergency shut down, there were smoking flares, maximum hourly CO emissions were exceeded, and the 24-hour SO2 limit was exceeded.


Notes: ARKS was, at the time prior to the power outage, being properly operated. All emission control devices were operating properly and no emission exceedances were noted prior to the power outage. ARKS took all reasonable steps to minimize levels of emissions that exceeded the emissions standards and other requirements in the permit. All emission control devices were operating properly and the emergency shutdown was conducted in accordance with the Startup, Shutdown, Malfunction Plan (SSMP).
Carbon Monoxide: 374.6 pounds
Sulfur Dioxide: 500.0 pounds

Tank 80-8
Cause: Due to a power outage causing the emergency shutdown, light ends from Complex 1 were being diverted to Crude tank 80-8, causing oil to release out of the vent onto the floating roof through the roof drain and out onto the tank farm.

Followup: No

Notes: Diverted roof drain to sump and deployed absorbent boom.
Benzene: 1.4 pounds
Crude Oil: 345.0 pounds
