121815 2010-03-01 | FLARE - Shell's GO-1 Elevated Flare (EPN 1-90) | Cause: LDEQ report states, "cat cracker tripped due to main air blower problems." Refinery letter states there was an unexpected shutdown of Motiva's RCCU Process Unit; had to flare dry gas being fed to Shell's GO-1 Process Unity to meet specifications to prevent further contamination to GO-1 and need for additional flaring. FLARE. Followup: No Notes: RQ. Reportable quantities exceeded. File includes letters from both Motiva and Shell Chemical. Motiva letter dated 3/8/2010 references submitting a follow-up within 60 day and Shell letter references "a separate letter from Motiva dated 4/28/10," but follow-up letter from Motiva is not included in file. | 5,846.0 pounds |
130903 2011-04-28 | Flare: EPN 3-84 | Cause: A leak occurred at HIC-84, along the downstream block valves, allowing nitrogen to enter the column causing a rapid pressure increase. The distilling unit upper crude column became overpressured, and PCV-195 opened the flare to relieve pressure in the column. EPN 3-84 Flare at Shell was used because the Motiva flare was upset and the pilot light was out. Original upset occurred at Motiva DU-5 Crude Unit with a notrogen leak into the Upper Crude Column. Followup: No Notes: The Shell report for the motiva release was dated May 5th, 2010 instead of 2011. | |
154210 2014-02-27 | RCCU | Cause: On 2/27/2014, an unexpected leak occured on Motiva's Residual Catalytic Cracking Unit (RCCU) second cyclone dip leg. Due to the location of the leak, the catalyst leak cound not be safely repaired while the unit was fully operations. A partial shutdown of the RCCU was conducted to stop the leak and complete repairs. While the unit was partially shut down, flaring occured intermittently at the RCCU Elevated Flare (EPN FE201) to safely stabilize equipment that was still operational. During the start up of RCCU, untreated dry gas was flared at the GO1 Elevated Flare. Followup: Yes Notes: To minimize additional unit upset and to safely repair the catalyst leak , the RCCU Unit was partially shut down in a safe manner. The catalyst leak was stopped and the second cyclone dip leg was repaired. The original report and the first follow up report included in the event description that untreated dry gas was flared at the GO1 Elevated Flare during the start-up of RCCU. This was not included in the final follow up report. Additionally, two follow up reports were sent by Motiva, the first dated 4/24/2014 to provide a 60 day follow up. In this correspondence it is stated that they will provide a second update within 60 days, as data gathering and investigation was ongoing. The final follow up report was received on 6/24/2014. | No information given |
