Accident Classified As:
Cause of Problem: Corrosion
the cause of the leak was isolated corrosion on a weld. A leak of spent sulfuric acid, D002, was discovered from an Alkylation line. The line was blocked out and purged with nitrogen to stop the leak. The spent acid was neutralized using soda ash and the contaminated soil is being remediated
Discharge Preventable - No
Notes/Remedial Actions
The leak was not preventable because the inspection data indicated the line was satisfactory until 2007. Subsequent inspection data confirmed that the leak was due to localized corrosion and not predictable. Remedial Measures - the leaking section of the pipe will be replaced. The reportable quantity for D002, Corrosive Wastes was exceeded
