2006-08-16		E-205 A/B exchanger bank on the Heavy Cat Naptha Unit
Cause: the E-205 A/B 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.

Followup: No

Notes: 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 benzene, toluene, naphthalene, volatile organic compounds, xylene mixed isomers, and o-xylene were exceeded. It is possible that the reportable quantities forylene and p-xylene were also exceeded, but available stream specification data does not allow differentiation between the these two isomers		2.0 pounds
