98478 2007-06-03 | Tank TK-8552 5-77 St. Rose Flare Tank TK-8553 | Cause: During a crude tank switch there was a unit upset when water and emulsion from a feed tank was introduced into the process, leading to the over pressuring of a de-salter vessel to the flare, a spill of water and emulsion to the water treatment facility and the shutdown of the compressor with additional flaring. During this unit upset tanks TK-8552 and TK-8553 roof legs inadvertently landed on the floor Followup: No Notes: Initial written report issued 6/20/07 but investigation revealed additional vent streams were routed to the flare so the numbers were updated on 8/14/07. To prevent this the water in the crude oil tank should have been drained prior to being placed in service. The crude tank was switched back to prevent further water and emulsion from being fed into the unit. Necessary steps were taken to clean up the wastewater treatment facility & return unit to normal. Tanks TK-8552 and TK-8553 were refilled to their normal levels. In the future, the water in the crude tank will be drained before the tank is placed into service | Xylene: 101.0 Toluene: 110.0 pounds Hydrogen Sulfide: 101.0 pounds Ethylbenzene: 1,000.0 pounds Hexane: 5,027.0 pounds Benzene: 18.0 pounds Sulfur Dioxide: 513.0 pounds Volatile Organic Compounds: 5,686.0 pounds Particulate Matter: 5,019.0 pounds Nitrogen Oxide: 112.0 pounds Carbon Monoxide: 5,558.0 pounds |
No LDEQ Reported 2008-09-20 | 5-77 (St. Rose Flare) | Cause: Loss of steam pressure when a tube failed in the boiler resulting in flaring Followup: No Notes: The boiler tube failure could not be predicted. Shut the process unit down until boiler repairs could be completed. The incident will be investigated and appropriate corrective actions will be implemented to prevent reoccurrence | Carbon Monoxide: 585.0 pounds Hexane: 0.8 pounds Nitrogen Oxide: 107.0 pounds Particulate Matter: 20.0 pounds Sulfur Dioxide: 75.0 pounds Volatile Organic Compounds: 386.0 pounds |
No LDEQ Reported 2008-07-17 | 5-77 (St. Rose Flare) | Cause: A bearing failed on the vent gas compressor for the vacuum unit. Followup: No Notes: The bearing failure was not predictiable. The compressor was shut down and a valve to the St. Rose flare was opened to lower and control the seal drum pressure. The compressor was replaced with a spare and the unit was returned to normal operating conditions. The spare will be replaced with the repaired compressor during the next unit outage | Carbon Monoxide: 8.1 pounds Hexane: 0.0 pounds Nitrogen Oxide: 1.5 pounds Particulate Matter: 0.3 pounds Sulfur Dioxide: 4.2 pounds Volatile Organic Compounds: 4.7 pounds |
