Cause of Problem: Process Upset

The 592 Sulfur Recovery Unit (SRU) has 3 combustion air blowers. Usually, 2 are on line. On 12/5, one of the two operating blowers tripped due to a thermal overload. This drop in air discharge pressure activated the Low Combustion Air Pressure alarm which shutdown combustion in the SRU Reaction Furnace. This activated the Sour Water Stripper (SWS).

Discharge Preventable - No Information Given

No Information Given

Notes/Remedial Actions

The refinery initiated "sulfur-shedding" procedures until SRU could be brought back online.
