Risk analysis to be implemented for refinery ESPs
On February 18, 2015, an explosion occurred in the ExxonMobil Torrance, California refinery’s Electrostatic Precipitator (ESP); a pollution control device in the fluid catalytic cracking (FCC) unit that removes catalyst particles using charged plates that produce sparks during normal operation. The incident occurred when ExxonMobil was attempting to isolate equipment for maintenance while the unit was in an idle mode of operation. Preparations for the maintenance activity caused a pressure deviation that allowed hydrocarbons to backflow through the process and ignite in the ESP. The U.S. Chemical Safety and Hazard Investigation Board (CSB) identified several process safety design weaknesses in the Torrance refinery FCC unit at the time of the incident. As a result, the CSB made four recommendations to Torrance Refining Company LLC. This recommendation is specific to requiring a siting risk analysis be performed of all ESPs and the implementation of appropriate safeguards.

Electric Fuel Control Valve Streamlines Plant Operations
A Frame 6B-powered cogen plant in California was plagued with fuel-gas valve problems, usually requiring at least a man-shift’s worth of work each outage to disassemble, clean seats/plugs, and reassemble. One solution is to reheat the fuel gas to above the dew point (120-130F) in between the valves, but this is considered far from ideal. The better solution proved to be replacing the original valve with a “smart” electric control valve in the same location as the original and a separate solenoid-operated stop/isolation valve about 6 ft upstream—just outside and below the turbine enclosure.
