Accident Classified As: No Information Given
Cause of Problem: Equipment Failure
Relief valve on the depropanizer column at the Residual Catalytic Cracking Unit had lifted. Due to the inclement weather conditions, the pilot tubing for the Relief Valve was frozen which caused the Relief Valve inlet block valve to remain closed resulting in the relief valve to fail in the open position.
Discharge Preventable - No Information Given
Notes/Remedial Actions
A steam hose was applied to the pilot tubing to defrost the tubing. Once the pilot tubing was thawed, the RV inlet block valve was opened and the RV was reseated. Motiva reports they will submit an update within 60 days. That update is not available at this time.
