Accident Classified As: Reportable Quantity
The 30 SRU malfunctioned resulting in excess sulfur dioxide emissions to the atmosphere. Excess emissions were emitted from the 30 TOX stack to the environment and rapidly dispersed.
In the June 6th follow-up report, they found that they experienced a sharp increase in Sulfur of 120 into the 30 SRU. The increase Sulfur loaded correlated to change the feedstock. The increase sulfur loaded into the 30 SRU exceeded the design limits of the system which ultimately led to unit instability.
The permitted SO2 rate was exceeded and reportable quantity were exceeded for the reporting hour of 11:00. Total SO2 emissions for the reporting hour of 11:00 were approximately 666 lbs., and total SO2 emissions in excess of the permitted limit were 551 lbs.
