Accident Classified As: Reportable Quantity
A packing leak developed on the seal of the fire eye cleaning device causing it to malfunction during routine maintenance and allowed combustion gases to escape to the atmosphere and shutting down Train 1 of the SRU (Sulfur Recovery Unit) sending acid gases to the FGM. Flared from flare 1 at a reportable quantity of H2S/SO2.
The malfunction of the cleaning device was unpredicted and unforeseen.
Unit operations were adjusted to minimize the duration and severity of flaring. The SRU Train 1 was switched to oxygen mode so it could process refinery acid gas. Sulfur pit vents on both trains were opened until SRU 1 could process them. To prevcnt this from happening again a re-engineered fire-eye cleaning tool will be constructed. This is expected to be completed by December 31, 2011. CRLLC will not utilize the fire-eye cleaning tool until modification to the tool has been completed. Two employees received first aid treatment. No chronic or acute health risks are anticipated as a result of this release. There was no emergency condition as a result of this release. NO SPOC or LDEQ report.
