|LDEQ Accident Number
|Point Source(s)||Notes||Amount of Release|
|Fresh acid line to Alkylation unit reactors||Cause: The fresh acid line to the Alkylation unit reactors developed a leak originating from a Furmanite manufactured box installed to control a prior leak.|
Notes: Upon discovery of the leak, Furmanite was contacted and the manufactured box was re-pressurized and sealed. The leak was corrected and the line was returned to normal service duty.
|alky unit's tank L-431||Cause: Alky unit's fresh sulfuric acid tank L-431 was leaking from a one inch flange on the north side.|
Notes: BRQ. Refinery letter states that "final calculations confirm that no reportable quantities were exceeded." The fresh and spent acid tanks were equalized to reduce the pressure in the fresh acid tank L-431 to slow the leak rate. Bolts on the leaking flange was replaced, however that did not stop the leak. Therefore, a sealant material was pumped into the nozzle of the leaking flange and was wire wrapped in order to provide a permanent seal. No LDEQ report. Refinery letter only.
|Alkylation Unit||Cause: On 4/25/2014 the operators at Motiva's Alkylation Unit discovered the check valve of a transfer pump leaking sulfuric acid into the secondary containment.|
Notes: The pump was immediately shut down to stop the leak.
