Honeywell (289, 183605), Baton Rouge

Causal Factor: Equipment Failure

LDEQ Accident Number
Accident Date
Point Source(s) Notes Amount of Release
78603

2005-04-28

Cause: While loading chloroform from a rail car to the storage tank, chloroform was released from the storage tank conservation vent into the atmosphere. The relief valve opened because of excess nitrogen being introduced into the tank due to a non-working dip line in a rail car.

Followup: No

Notes: The refinery reviewed tank inspection process and replaced the relief valve on the chloroform storage tank vent condenser.
Chloroform: 7.0 pounds

2005-04-05

Cause: While loading chlorotrifluoroethylene (G-1113) from a storage tank to a ton cylinder, a release occurred to the process sump via stack drain line due to improper valve alignment.

Followup: No

Notes: The valve on the storage line was closed to stop any flow of chlorotrifluoroethylene (G-1113) to the cylinder. Plant personnel were evacuated until determination was made by the emergency response team that the area around the release was safe. The facility reviewed computer data for trends, operating procedures, training, opened up several lines for possible pluggage, replaced several remote operated valves to prevent any leakage, re-routed the ton cylinder loading system such that the material will be contained and returned to process for any misalignment of the valves, etc.
chlorotrifluoroethylene: 537.0 pounds

Cause: While loading chlorotrifluoroethylene (G-1113) from a storage tank to a ton cylinder, the release occured to the process sump via stack drain line due to improper valve alignment.

Followup: Yes

Notes: The valve on the storage tank was closed to stop any flow of chlorotrifluoroethylene (G-113) to the cylinder. Plant personnel were evacuated until determination was made by the emergency response team that the area around the release was safe. As a result of this incident, Honeywell reviewed computer data for trends, operating procedures, training, opened up several lines for possible pluggage, replaced several remote operated valves to prevent any leakage, etc.
chlorotrifluoroethylene: 837.0 pounds

2006-08-17

Cause: The chemical backed up into the nitrogen header from the intermobile container (ISO). The release was possibly the result of a failed valve. The blend's trade name is AZ-50, and includes trifluoroethyane and pentafluoroethane.

Followup: No

Notes: The refinery suspended activity for the day. At the time of the SPOC report, the refinery was uncertain whether or not the release reached RQ. Amount of Trifluoroethane and Pentafluoroethane released is unknown.

24m
Cause: Someone noticed a temperature change in one of the processes in the plant, which led this person to check a relief valve. The relief valve, which is on top of the #1 Chloroform Storage Condenser, was leaking. Both of the possible chemicals released would have evaporated before they hit the ground. None of the air monitors 15 ft below the condenser went off.

Followup: No

Notes: The relief valve reseated after the incident. Honeywell is continuing to investigate what exactly was released. Amount of dichlorotrifluoroethane and chloroform released is unknown.

relief valve-343
Cause: The G-1113 production unit experienced a pressure drop during a time when the unit was down and not operating. Pressure relief valve-343 was leaking.

Followup: No

Notes: Condenser relief valve was switched to the spare and the leak was isolated. At the onset of, and for the duration of the event, the unit was in a blocked in state with no feed additions. The relief valve has been sent off for testing to confirm the failure.
1,1-Dichloro-2,2,2-Trifluorethane (G-123): 527.4

relief valve
Cause: Relief valve from the organic recycle vaporizer was leaking. Release occurred what a relief valve on a vapor riser lifted releasing a small amount of chemical into the air. Leak lasted about 10 min.

Followup: No

Notes: The relief valve was immediately blocked in and removed for repair and the spare relief valve was placed into service.
1,1-Dichloro-2,2,2-Trifluorethane (G-123): 753.0 pounds
