After an upset at the Crude Unit, minimal quantities of Black Powder would plug the suction screens in front of the pumps. This could happen multiple times per shift, leading to constant swapping of pumps, insulation removal and pipe disassembly to remove the “witch’s hat” strainers for cleaning. Often, the line leading to the strainer was also plugged, the pipe had to be manually cleaned all the way back to the valve.
Install a BPS Magnetic Separator specially designed with inline connections.
The magnetic separator had sufficient holding strength to capture large quantities of Black Powder that had been plugging the screens. Since installation, the efficient cleaning routine has prevented outage incidents.
The separator also prolonged the change intervals on the coaleser; the clay filter elements’ operating lives were extended to the point that 15 sets of changes were eliminated annually. The resultant product cleanliness allowed for the Diesel Fuel to be sold at a premium.
