While swapping the bottoms pump around pumps in U26 (Fluid Catalytic Cracking Unit Gas Con Unit) after maintenance, BPA flow was lost for approximately 20 minutes resulting in flaring from the debutanizer. The flaring event began on April 29, 2014 at 10:47 adn stopped at 11:15.
The incident investigation found that Management Systems Failures were part of the cause of the event.
To contain the release, refinery workers attempted to start second pump, reduced the rate of the Crude Unit, Heavy Gas Oil Hydrotreater, HF Alkylation Unit, Gasoline Desulfurization and the Diesel Hydrotreater units until incident was under control. An incident investigation was conducted to determine the causes of the incident. Per this investigation, root causes were identified as Management System/SPAC Not Used/Enforcement Needs Improvement. Multiple recommendation items were identified to help prevent a recurrence of the event, including: 1) Update the generic pump switching guideline in each Operating Manual to include specific run verification steps (Complete by 11/2014), 2) Develop a "lessons learned" bulletin for the incident. Discuss how the causal factors lines up to result in the environment incident (Completed), 3) Review the "lessons learned" bulletin with operating personnel via a start-of-shift tool box meeting (Completed). Report on 9/9/14 states that an initial follow-up report was submitted on 5/6/14. This report is not available on the Louisiana Department of Environmental Quality's Electronic Data Management System (EDMS) as of 1/7/2015.
