2007-02-16		Rich Stage Absorber Tower
Cause: While making routine rounds, an assistant operator on the Isopropyl Alcohol Unit discovered a leak on the sixth level of the Rich Stage Absorber Tower. The leak was caused by a failure of the thermowell assembly.

Followup:

Notes: Personnel immediately began to isolate and shut down the tower. Elevated fire monitors were activated which sprayed water on the release to minimize emissions to the air. Feed was blocked out of the tower, the liquid drained to other process equipment, and the tower was depressured to the gas recovery system. The failed thermowell assembly was replaced. The failed thermowell assemblly was sent to an outside lab for metallurgical analysis to determine the cause of the failure.		892.0 pounds
