Accident Classified As: Below Reportable Quantity (BRQ)
There was excess SO2 emissions as a result of a plugged quench column. The plugged column was drained frequently to prevent further operational problems but required a temporary bypass of the tail gas treating unit #2 (TGTU 2), which treats gas from the SRU3 and sends it to the Sulfur recovery unit incinerator no. 2 (SRUI2).
No information given.
To minimize excess emissions the maximum load possible was shifted to SRU 2 and acid gas production was reduced, feed to the SRU plants, by reducing FCCU and Diesel Hydro-treating processing rates during this period to minimize the load on SRU3. The column was drained frequently due to the timing of the planned turnaround versus longer TGTU2 outage that would have resulted in more overall SO2 emissions and a reportable quantity exceedance. Notification states that the discharges was in exceedance of the SO2 permit level that spanned a 7 day period. Also exceeded the maximum lb/hr permit level (4.25) for the source.
