Accident Classified As: No Information Given

Cause of Problem: Piping or Tubing

ExxonMobil re-evaluated a leak that they had inside of a furnace. Tube inside of a furnace has a small leak, which is causing ethane to be released into a section of the furnace that is not designed for combustion.

Discharge Preventable - No Information Given

Notes/Remedial Actions

The ethane was combusting and forming nitrogen oxide. The furnace is fairly large and shutting it down would cause flaring that would release thousands of pounds of nitrogen oxide. A strategy to repair the tube was to be developed. Nitrogen oxides were released at 16 lbs per day. Release is ongoing. Amount of release is unknown at this time.
