| LDEQ Incident Number Incident Date |
Point Source(s) | Notes | Amount of Release |
| 05-BB005-210 2005-05-11 | K3304 | Cause: Leak on the Hydrodesulphurization (HDS) Unit Off0gas Compressor K-3304 Followup: No Notes: Sweet streams (lower Sulfur content) were routed to the flare to minimize sour gas flaring. Process unit output was adjusted in order to minimize the total amount of waste gas being sent to the flare. | 16.0 pounds |
| 78361 2005-04-19 | K-401 (waste gas compressor number 2) | Cause: Waste gas compressor number 2 (K-401) automatically shut down, automatically diverting waste gas to the flare system. Followup: No Notes: Low-Sulfur content streams were routed to the flare to minimize sour gas flaring. Output was adjusted to minimize total amount of waste being sent to the flare. Same language about doing an investigation to understand the underlying cause and prevent future incidents. | 1.0 pounds |
| 78341 2005-04-17 | K-401 (waste gas compressor number 2) | Cause: Waste gas compressor number 2 (K-401) automatically shut down, automatically diverting waste gas to the flare system. Followup: No Notes: Low-Sulfur content streams were routed to the flare to minimize sour gas flaring. Output was adjusted to minimize total amount of waste being sent to the flare. | 1.0 pounds |
| 78226 2005-04-13 | K-401 (waste gas compressor number 2) | Cause: Waste gas compressor number 2 (K-401) automatically shut down, automatically diverting waste gas to the flare system. Followup: No Notes: Low-Sulfur content streams were routed to the flare to minimize sour gas flaring. Output was adjusted to minimize total amount of waste being sent to the flare. Letter rescinds report of nitric oxide because below reportable quantity. | 2.0 pounds |
| 05-BB005-157 2005-04-06 | K-402 (Refinery waste gas compressor number 3) | Cause: K-402 unexpectedly shut down. Shortly after shutdown, refinery personnel identified the cause of the shutdown as a malfunction of the compressor motor ignition system. Followup: No Notes: The compressor motor was repaired and the compressor restarted, ending the incident. | 27.0 pounds |
| 77936 2005-03-31 | K-400 (Refinery waste gas compressor number 1) | Cause: Refinery waste gas compressor number 1 (K-400) unexpectedly shut down. Refinery waste gas automatically diverted to the flare system. Followup: No Notes: Adjustments made to the fuel/air mixture and K-400 restarted. | 1.0 pounds |
| 77659 2005-03-17 | No information given | Cause: Waste gas compressor number 2 (K-401) automatically shut down due to a high temperature. Followup: No Notes: Letter rescinds verbal report because incident was not reportable. No release to atmosphere. | 2.0 pounds |
| 05-BB005-128 2005-03-02 | Waste Gas Compressor Number 4 (K-406); Copper tubing connecting C-435 (first stage suction drum) to high-level instrumentation | Cause: Waste gas compressor number 4 (K-406) shut down due to failure of piece of copper tubing connecting C-435 to high-level shutdown instrumentation. When it failed, a false high level reading was recorded, causing automatic safety shutdown system to become engaged. Followup: No Notes: Low-Sulfur content streams were routed to the flare to minimize sour gas flaring. Output was adjusted to minimize amount sent to the flare. C-435 was retubed, K-406 was checked and restarted. | 8.0 pounds |
| 05-BB005-106 2005-02-04 | Electrical breaker G-457; Waste gas compressor number 2 (K-401) | Cause: Electrical breaker for G-457 malfunctioned. Waste gas compressor number 2 (K-401) shut down as a result of the electrical power outage and refinery waste gas was diverted to safety flare system. Followup: No Notes: Low-Sulfur content streams were routed to the flare to minimize sour gas flaring. Output was adjusted to minimize total amount of waste being sent to the flare. Note: the breaker for G-457 had been identified for repair and was supposed to be replaced that week. | 3.0 pounds |
| 05-BB005-93 2005-01-22 | K-406 (waste gas compressor number 4) | Cause: Waste gas compressor number 4 (K-406) unexpectedly shut down. Waste gas was automatically diverted to refinery safety flare system. Followup: No Notes: Note: This compound was not included in the body of the letter. It was listed in a chart attached to the letter. | 6.0 pounds |
| 76362 & 76355 2005-01-21 | Hydrocracker Light Ends Plant Butane Splitter Tower & LEP Depropanizer Tower Bottoms Flow Control Valve 50FC060 | Cause: (1) 0600 hrs: Hydrocracker Light Ends Plant (LEP) Butane Splitter Tower began to overpressure because LEP Depropanizer Tower Bottoms Flow Control Valve (50FC060) had failed in the open position, letting propane to exit to the Butane Splitter. (2) 1700 hrs: Butane Splitter again began to overpressure due to the presence of propane. The level indication on the level instrument was detecting a false reading. Followup: No Notes: Letter speaks of two incidents on same day at 0600 hrs and 1700 hrs but attached report shows three incidents: (1) 4:05 a.m. lasting 3h 42m; (2) 3:15 p.m. lasting 41m; (3) 4:30 p.m. lasting 1h 25m. Amounts of compounds are only given in totals for all 3incidents. | 5.8 pounds |
| 05-BB005-67 2005-01-06 | K-406 (waste gas compressor number 4) | Cause: K-406 unexpectedly shut down and waste gas was automatically diverted to refinery safety flare system. Followup: No Notes: Sweet streams (lower Sulfur content) were routed to the flare to minimize sour gas flaring. Process unit output was adjusted in order to minimize the total amount of waste gas being sent to the flare. Shortly after shutdown, personnel re-started K-406 restoring the systems ability to process available refinery waste gas streams, ending the incident. | 1.0 pounds |
