Accident Classified As:
Cause of Problem: Corrosion
E-513 A exchanger on the 2 Light Ends unit was leaking hydrocarbon to Cooling Tower #25. The leak is believed to have come from corrosion on the hydrocarbon side of the tube bundle.
Discharge Preventable - No
Notes/Remedial Actions
This incident was not preventable because previous inspection reports indicate that this exchanger bundle is less than 6 years old and in serviceable condition. Remedial Measures - this bundle will either be replaced with a new bundle or repaired. A metallurgy upgrade to 410 stainless steel is being evaluated. Replacement and/or upgrade of exchanger bundles in similar is also being considered. LDEQ reportable quantities for butenes, propylene, highly reactive volatile organic compounds, and 1,3adiene were exceeded
