Accident Classified As:
Cause of Problem: Corrosion
the E-205 C/D exchanger bank on the Heavy Cat Naptha unit was leaking to Cooling Tower #27. The leak is believed to be from corrosion on the tube bundle.
Discharge Preventable - No
Notes/Remedial Actions
This incident was not preventable because the inspection data for this bank of exchangers did not indicate that a failure was imminent. These bundles were tested in January 2005 and were found to have no leaks. Remedial Measures - the exchanger bundle will be inspected and repaired or replaced as appropriate. The reportable quantities for xylene, benzene, toluene, naphthalene, and volatile organic compounds were all exceeded
