Releases of Nitrogen Oxide

LDEQ Accident Number
Accident Date
Point Source(s) Notes Amount of Release
84196

2005-11-30
C-Szorb Unit
Cause: Fire due to a flange leak on the feed exchanger to the S-Znob Unit.

Followup: No

Notes: Fire was extinguished, the course was isolated and the unit was shut down. Incident was preventable; flake leak caused by unequal heat expansion due to incorrect application of insulation.

Boiler B-76001(EP-109)
Cause: Instrument failure. During startup of the boiler, the positioned for the flue gas recirculation damper failed, resulting in excess emissions of Nitrogen Oxide. The positioned is believed to have been damaged by Hurricane Rita.

Followup: No

Notes: A replacement for the positioned was ordered, delivered and installed by the end of the day.

Area A-North Flare (EP-64)
Cause: A relief valve on the stripper is the 6HDS lifted due to a process upset caused by a hydrogen compressor shutdown & consequent unit upset.

Followup: No Information Provided

Notes: A management environmental review will develop a plan to identify leaking RVs and troubleshoot the flare system during relied events/upsets so that future releases do not exceed permit limits. HAZMAT#0606318

Area B - South Flare (EP-31)
Cause: The South Flare Recovery Compressor was shutdown to perform relief valve inspection work.

Followup: No Information Provided

Notes: Once inspection was complete, compressor was put back in service. HAZMAT#
88366

2006-06-06
Area B- South Flare (EP31)
Cause: see notes. Intermittent power surge due to malfunctions at the Entergy Power Company. Emissions resulted from power failure.

Followup: No Information Provided

Notes: Power failure. Restarted and/or isolatedpertinant units to prevent further impact. HAZMAT#
199.0 pounds

2006-03-18
Area B- South Flare (EP31)
Cause: Emissions occurred when the SFGR compressor system was shut down to install relief valves.

Followup: No Information Provided

Notes: South Flare Caustic Scrubber was in service during this outage. HAZMAT#
less than 1
86154

2006-03-02
Area C- North Flare (EP-64)
Cause: The No. # Crude Unit shut down for turnaround resulted in excess emissio

Followup: No Information Provided

Notes: No Information given.

2006-02-27
Area B -South Flare (EP31)
Cause: South Flare Gas Recover compressor was shutdown to facilitate flare work on W-10.

Followup: No Information Provided

Notes: Work is planned to minimize duration of compressor outage thus minimizing quantity of pollutants releases. HAZMAT #06-01195
85943

2006-02-24
Area B- South Flare (EP31)
Cause: Release caused by poor NaHS operation and south flare caustic scrubber startup not completed.

Followup: No Information Provided

Notes: South Flare Caustic Scrubber is in full operation. HAZMAT # 06-01158

Excel Paralubes' Boiler 76001 (EP109)
Cause: see notes. Flue gas damper closed during shutdown from loss of electricty on 2/15. After startup, the damper was not opene

Followup: Yes

Notes: Power Failure. Investigation and sharing of key learnings with operations will occur. HAZMAT #06-01023.

North Flare (EP-64)
Cause: see notes. A loss of electrical power occurred caused by failure of an Entergy own electrical transformer. The electrical power loss resulted in emergency shutdown of the majority of process units. Emergency shutdown instrumentation directed hydrocarbon gas streams to the refinery complex flares resulting in excess emissions of SO2, H2S, and NOx from the complex's North and South Flares. Additional flaring of gas streams resulted from the staggered process unit and various start up once electrical power was restore

Followup: Yes

Notes: POWER FAILURE. A root cause failure analysis is being conducted on this incident. Its results will be used to develop actions that will potentially preclude a recurrence.

Excel Paralubes' Boiler 76001 (EP109)
Cause: HDC loss of containment occurred. Nox instrument indicated a release of Nox but futher investigation determined this did not occur. Instrument air was lost during HDC incident and fuel gas BTU analyzer used in Nox calcs failed. Also, Nox CEMS sample system plugged from plume blowing from the HDC to this boile

Followup: No

Notes: Instrument malfunction gave false reading indicating excess emissions. No remedial action taken.

Excel Paralubes SRU (EP-111)
Failed check valve
South Flare (EP-31)
West Flare (EP-110)
Cause: Loss of containment occurred due to the structural failure of check valve on the discharge of Heater H-11001, which allowed a hydrocarbon release to the atmosphere. The hydrocarbons ignited causing significant damage to the process piping and insturmentation associated with the heater

Followup: Yes

Notes: root cause failure analysis is being conducted. Its results will be used to develop actions that will preclude a recurrence of this event.
