The unit was shutdown and fin fan exchanger was purged with nitrogen. Followup: Yes Notes: RQ. Unit was shutdown and exchanger purged with nitrogen. LDEQ report states that DEQ database was checked several times for a 60 day follow-up notification but no report was sent within 60 days. When contacted they stated no knowledge of 60 day notification requirement. The facility then submitted the second follow-up report notification with root cause analysis. According to the report, the event was not preventable. This facility referred to circuit rider for not submitting the second follow-up notification in accordance with LAC 33.I.3925.A.3 | 383.0 pounds |
| 126163 2010-09-06 | FCC regenerator flue gas scrubber vent FLARE: Flare #1 FLARE: Thox stack, Flare # 1 and 2 | Cause: Bus bar short to ground due to unsealed air gaps created a voltage dip which resulted in power loss to multiple units which then had to flare. Pressure imbalance in the FCC regenerator resulted in loss of catalyst through the regenerator flue gas scrubber vent. FLARE. Followup: Yes Notes: "To reduce the likelihood of recurrence, sealant was installed between the bus bars and supports in PS 7711 and acoustic inspection is being performed at another power station that was designed and installed by the same contractor." Refinery letter states that "there was no emergency condition related to this release and the resulting community exposures would not be expected to have acute or chronic health impacts." | 283.0 pounds |
| 123040 2010-04-27 | flare #1 | Cause: Compressor inadvertently tripped while executing Emergency Block Valve Prevention Maintenance Program procedure on it--sent material to flare. Followup: No Notes: Operations team secured the unit and started up the compressor, full evaluation and troubleshooting will be addressed during next shutdown. Will not perform EBV maintenance program in the meantime. | |
| 122546 2010-04-03 | no information given | Cause: "Unloading olefin truck--vent line to flare left open"--no details. Followup: No Notes: no information given | |
| 134471 2011-10-10 | FLARE-No. 1 Flare; SRU 1 | Cause: There was sudden unexpected loss of O2 supply from Air Products causing SRU1 to immediately shut down. Acid gas (SO2 and H2S) was released intermittently through Number 1 Flare. SRU 1 was sole operating SRU at the time of incident, as SRU 2 was shutdown for maintenance. Followup: No Notes: Steam controllers have been repaired and rebuilt. There was also an evaluation of alarm changes to provide more response time. EPA Acid Gas Flaring report included. LDEQ conducted an investigation in response to this incident on 12/8/11. | 595.0 pounds |
| 133880 2011-09-11 | FLARE: Flare No. 1 | Cause: A packing leak developed on the seal of the fire eye cleaning device causing it to malfunction during routine maintenance and allowed combustion gases to escape to the atmosphere and shutting down Train 1 of the SRU (Sulfur Recovery Unit) sending acid gases to the FGM. Flared from flare 1 at a reportable quantity of H2S/SO2. Followup: No Notes: Unit operations were adjusted to minimize the duration and severity of flaring. The SRU Train 1 was switched to oxygen mode so it could process refinery acid gas. Sulfur pit vents on both trains were opened until SRU 1 could process them. To prevcnt this from happening again a re-engineered fire-eye cleaning tool will be constructed. This is expected to be completed by December 31, 2011. CRLLC will not utilize the fire-eye cleaning tool until modification to the tool has been completed. Two employees received first aid treatment. No chronic or acute health risks are anticipated as a result of this release. There was no emergency condition as a result of this release. NO SPOC or LDEQ report. | 220.0 pounds |
| 132776 2011-07-29 | Flare 1 | Cause: On 01/28/11, at approximately 9:00am, the amine unit was being taken out of service for a planned maintenance activity. During the course of the shutdown, the DGA circulation in the contactor decreased. The reduced flow occurred concurrent with the loss of the LPG compressor. As a result, there was an H2S breakthrough to the refinery fuel gas system at approximately 1 minute. This event resulted in 86 lbs of excess SO2 emissions. Followup: No Notes: Fuel Gas incident- The shift leader recognized the problem within 15 minutes of the start of the event and immediately increased circulation to stop the H2S breakthrough and mitigate the SO2 emissions potential. Updated procedures to ensure shutdown activities include awareness of circulation rate and interaction with other unit operators. Refresher training will be conducted with unit personnel on revised procedure. In a separate event at 12:58am, the flare gas management compressors briefly shutdown due to elevated molecular weight (MW) gas which resulted in increased SO2 emissions from the fired combustion units of 481 lbs excess SO2 | |
| 132721 2011-07-23 | Flare | Cause: On July 23, 2011 at approcimately 23:33 hours, a safety valve on the propane/polypropylene mix drum, D9007 relieved to the No. 1 Flare, resulting in intermittent flaring, and consequently resulting in emission of sulfur dioxide in excess of the reportable quantity of 500 lbs. Incident 11-04337 occurring on July 21, 2011 caused a buildup of hydrocarbons in the compressor seal water decreasing the capacity of the compressors which normally have the capacity to contain this volume. Followup: No Notes: The seal water on the FRM compressors was changed out as the hydrocarbon buildup contributed to the flaring. Pressure build up in the spheres occurred before the seal water could be changed out in the compressors causing intermittent flaring. The venting could not be delayed as it would have been a process safety issue. Flaring does not normally occur from these procedures. | |
| 131805 2011-06-13 | fin fan on the Cat Feed Hydrotreater | Cause: Aire release of hydrogen sulfide and compressed flammable gas from fin fan on Cat Feed Hydrotreater at Chalmette Refining. According to the refinery letter, "the Cat Feed Hydrotreater (CFHT)Unit lost power during a transformer switch, resulting in a pressure increase, and the subsequent leak on the E-7778 fin fan."
It was determined that the cause was premature corrosion in the overhead fin fans of the CFHT Unit. Followup: No Notes: RQ of hydrogen sulfide. BRQ of VOCs. Inventory was removed from the unit and system pressure was reduced in order to stop the leak and make necessary repairs Chalmette Refining retained U.S. Risk Management to perform community monitoring during the event. The fin fan tube was isolated until repairs and/or replacement are completed. | 111.3 pounds |
| 131070 2011-05-09 | PGC 2nd Stage Aftercooler | Cause: The PGC 2nd Stage Aftercooler leaked hydrocarbon vapors and compressed flammable gas was released to water. OFFSITE IMPACT: Mississippi River. Followup: No Notes: BRQ. Refinery letter states that release was below reportable quantities. The exchanger was isolated and the path to water was closed. A boom was deployed at the source and downriver. | |
| 130822 2011-04-26 | Fractionator Overhead Fin Fan | Cause: LDEQ states that a leak was observed in the Fractionator Overhead Fin Fan at the Cat Feed Hydrotreater, releasing compressed flammable gas and hydrogen sulfide. Followup: No Notes: RQ. Unit commenced an orderly and safe shutdown in order to stop the leak and make necessary repairs. | 304.0 pounds |
| 140083 2012-05-26 | Cause: The facility experienced malfunctions when the high pressure waste gas system was shut down in the Coker unit, releasing sulfur dioxide to the flare. Followup: No Notes: The high pressure waste gas system had been restored by the time of the LDEQ Incident Report. | 100.0 pounds | |
| 138541 2012-04-03 | #1 Flare | Cause: A high molecular weight gas was routed to the flare gas management system, which prevented the compressor from being able to pump the gas and caused the flare to open. Followup: Yes Notes: To stop the discharge, feed rate to the unit was reduced, reducing pressure, and eventually ending the release. A representative from Chalmette Refining contacted LDEQ Emergency Response on 4/4/12 when an all-clear was called, also providing the total release quantity of sulfur dioxide. No fire, injuries, or fatalities resulted from this incident |
