Accident Classified As:
-the E-553B exchanger on the Coker was leaking to Cooling Tower #44. The leak is believed to be from the corrosion on the tube bundle.
Remedial measures - The leaking tube on the E-553 exchanger will be plugged and the exchanger will be pressure tested before it is returned to service. The accident was not preventable because the exchanger had not leaked previously and the tube bundle was approximately 18 months old. The report letter to LDEQ states that the reportable quantities for benzene, hydrogen sulfide, volatile organic compounds, and 1,3-butadine were exceeded.
