111370

2008-12-11
Point Source(s):
Flare No 3 (19G-301)
Tail Gas Treating Unit 3 (77H-101)
Tail Gas Treating Unit 4 (78H-101)

Pollutant(s):
Nitrogen Oxide - BRQ
Carbon Monoxide - BRQ
Hydrogen Sulfide - 103 pounds
Sulfur Dioxide - 2,895 pounds
Particulate Matter - BRQ
Seal Oil - 791 pounds
Cause of Problem: Process Upset

Upset of the ebulated-bed residuum hydrocracker (H-oil Unit) with a series of fluctuating alarms. While responding to the alarms, operators noticed a fire on the compressor turbine casing and immediately responded to extinguish the fire. The primary cause of this event was a H-Oil unit malfunctioning local level controller on the sour oil seal pot causing the drain valve to remain open and lose reference gas pressure across the seal oil pot.
FIRE. Operations began to reduce production by reducing charge rates on units and to troubleshoot H-Oil recycle compressor and fin fan malfunctions. Immediate action was taken to begin the process of stabilizing, slowing down and shutting down the H-Oil unit and other units as necessary. Affirmative defense letter. Motiva inspected and completed insrumentation checks on the level control for thesour oil seal pots the level control drain valve and the level gauge. A faulty high-level switch was found and replaced. COR will schedulean operation's monitoring cycle to ensure proper sour oil seal pots level. COR will also add a level control loop for the sour oil seal pots levels during the next maintenance outage.

2008-10-19
Point Source(s):
Mississippi River

Pollutant(s):
Hydraulic Oil - 5 gallons
Cause of Problem: Maintenance/Procedures

While performing maintenance activities on the dock, hydraulic hose ruptured on a barge installing pilings.
River carried away spill before a cleanup crew could be assembled. Maintenance activities were discontinued and the failed hydraulic hose was isolated. This prevented additional hydraulic oil from being released to the river. The failed hose was replaced. Maintenance crews at dock inspected machinery to make sure all hoses were in acceptable condition.
