Accident Classified As: Below Reportable Quantity (BRQ)
The plant experienced a pipe leak in the OMNI 143A unit. The pipe integrity had been compromised during certain operating conditions of the unit that occur on an infrequent basis. These operating conditions are called catalyst burn downs. The pipe leak most likely developed during previous catalyst burn downs.
The discharge was determined to be unpreventable. This segment of pip was inspected on a frequent basis at vulnerable areas in order to prevent this trype of incident. However, this occurred in a straight run of the pipe segment, what was not a foreseen failure mechanism.
The unit was immediately shutdown to stop the leak. Water was also applied to the leak in order to minimize the emissions. The entire segment of the pipe that the leak occurred on was replaced with Teflon lined pipe in order to improve the integrity and prevent any future incidents.
