Accident Classified As: No Information Given
On May 20, at approximately 3:15 PM, a leak was detected from a fuel gas line near the Hydrocracking Unit. A failure analysis conducted on the failed section of the pipe indicated that increased water saturation and chloride content in the stagnant zone of the pipe was the cause of the degradation.
The testing conducted on the fittings and turbulent areas at bends, elbows, and tees in the surrounding area of the pipe failure indicated adequate pipe thickness. There were no indications that suggested the piping would fail in that area.
Immediate remedial action was to barricade the area and water was used to dissipate vapors from the release. The line was isolated and a clamp was installed to mitigate the leak. Onsite monitoring was conducted during the events and all results were zero. No emergency conditions or adverse offsite impacts resulted from this release.
