Accident Classified As:
excess emissions of sulfur dioxide occurred at the #3 SRU Incinerator stack due to a malfunction of the #3 SRU. The malfunction, a flameout in the #3 SRU TGTU Tail Gas Burner, resulted in an automatic TGT bypass. The MCR (Master Control Relay) connections were checked because and analysis of the Triconex output indicated a probable loose connection. A loose connection was found and repaired.
This was a self report to LDEQ with a follow-up report both from Murphy. The incident was not preventable because the loose connection was not a predictable human event. Remedial Measures - MOUSA inspected the unit and found a loose connection at the #48 terminal in the Master Control Relay for the #3 SRU. MOUSA tightened the connection and set up a Preventable Maintenance work order to inspect all critical relay connections during the next planned unit shutdown.
