Accident Classified As: No Information Given

Cause of Problem: Maintenance/Procedures

TDC was preparing a line for maintenance by isolating and purging it, and during this maintenance activity, TDC sent a high concentration of hydrogen sulfide containing gas to the South Flare System. Sudden spikes in flow from the third party NASH plant of a stream with high hydrogen sulfide concentration and sufficient flow overwhelmed the capacity of the South Flare Caustic Scrubber to adequately treat the material.

Discharge Preventable - No

The cause shall be designated as an agreed-upon malfunction for purposes of reviewing subsequent Flaring incidents.

Notes/Remedial Actions

The flow of high hydrogen sulfide gas to the system from a third party was enough to overwhelm the caustic scrubber system. Fresh caustic solution and water were added to the South flare scrubber during the event to keep the scrubber as effective as possible.
