Phillips 66 (2418), Belle Chasse
Causal Factor: Power Failure
| LDEQ Accident Number Accident Date |
Point Source(s) | Notes | Amount of Release |
| 78925 2005-05-10 | (308F-D-1) Low Pressure Flare; (308F-D-2) High Pressure Flare; (301-D-3) CO Bypass Stack; (591-D-21X) SRU Incinerator | Cause: Entergy experienced a ground fault and the backup supply failed to switch in a timely manner. Forced most process units to shutdown resulting in flaring and venting of CO. Two pressure valves relieved to the atmosphere. Followup: No Notes: With most of the process units down, there was isufficient feed to keep the SRU tail gas treater online. The tail gas from SRU 591 was routed directly to the SRU incinerator until other refinery process units restarted to provide sufficient feed to support stable TGT operation. There was some smoking form the flares. | Benzene: 216.0 pounds Carbon Monoxide: 38,536.0 pounds Hydrocarbon: 17,590.0 pounds Hydrogen Sulfide: 413.0 pounds Nitrogen Oxide: 668.0 pounds Sulfur Dioxide: 47,071.0 pounds |
| 78926 2005-05-10 | Texaco Pipelines LLC AL02 Liquid meter station at ConocoPhillips | Cause: A power failure at CP caused an automatic shut down causing a 1inch relef valve to release propylene. Followup: no Notes: Installed thermal relief on the pipeline | Propylene: 754.0 pounds |
| 90071 2006-08-17 | 308F-D-1 Low Pressure Flare; 308FD2 High Pressure Flare | Cause: An electrical fault caused a loss of power to the Alkylation Unit cooling tower and tripped the Delayed Coking Unit compressor and other equipment off line. Followup: No Notes: Stabilized unit allowing restart of the 891K1 compressor and stopping of the flaring off of 491V9 | Nitrogen Oxide: 13.7 pounds Sulfur Dioxide: 2,338.0 pounds |
| 89980 2006-08-15 | 308F-D-2 High Pressure Flare | Cause: An oil circuit breaker in the electrical substation supplying electricity to the Alkylation Unit and its cooling tower failed. This power interruption caused a loss of cooling water and tripped several pumps offline. Followup: No Notes: Plant personnel stabilized the unit to prepare AU 491 for restart. | Hydrocarbon: 7,898.0 pounds Nitrogen Oxide: 267.8 pounds |
| 87876 2006-05-16 | 308F-D-1 Low Pressure Flare | Cause: Malfunction with the bus bar caused the main circuit breaker supplying power to the Crude Unit 191, Saturated Gas Unit 7991 and the WWTP to trip. The power interruption caused unit upsets at the Crude Unit and Hydrotreating Unit 292. Followup: No Notes: Immediately switched power source to an alternative feeder. | Hydrogen Sulfide: 34.4 pounds Nitrogen Oxide: 29.5 pounds Sulfur Dioxide: 3,401.0 pounds |
| 99023 2007-08-29 | 308F-D-1 Low Pressure Flare, 308F-D-2 High Pressure Flare | Cause: Followup: Yes Notes: | Sulfur Dioxide: 605.0 pounds Hydrocarbon: 192.0 pounds Nitrogen Oxide: 14.0 pounds Hydrogen Sulfide: 6.0 pounds |
| 93785 2007-02-07 | 308-F-D-1 Low Pressure Flare | Cause: A 34.5KV lightning arrestor failed at Entergy substation. An insulator also failed on the disconnect switch. The opening of these breakers caused the Coker Compressor to trip off line. The compressor's suction stems is automatically diverted tot he Low Pressure Flare. Followup: No Notes: Three arrestors and a failed insulator are being replaced. | Sulfur Dioxide: 646.9 Hydrogen Sulfide: 6.5 Nitrogen Dioxide: 8.3 Hydrocarbon: 79.9 |
| 113974 2009-04-06 | 308F-D-1 (Low Pressure Flare); 191-PSV-009 Unit 191-PSV-009 | Cause: A power failure occurred as a result of grid failure due to scheduled maintenance by Entergy. Entergy's method did not allow for ConocoPhillips to secure an alternative source while the main grid was down. The refinery thus had to initiate an emergency shutdown. As a result, the refinery had to employ the low pressure flare. Followup: No Notes: Entergy has proposed a three phase project that will build additional substations within the electrical power grid over the next five to eight years to improve its reliability. Entergy is currently seeking federal funding for this project. | Sulfur Dioxide: 12,914.0 pounds Hydrogen Sulfide: 130.0 pounds Hydrocarbon: 504.7 pounds Nitrogen Oxide: 53.0 pounds Hydrocarbon: 58,184.0 pounds |
