A Gulf Coast refinery experienced high silicon antifoam usage approxi-mately 1 lb [0.5 kg] of silicon per thousand barrels) at the coker while using 60,000 cSt antifoam. This usage rate was well above the refining group’s other locations, which used approximately 0.25 lb of silicon per thousand barrels. As a result, a higher than desired amount of silicon was being carried over into the coker naphtha. In addition, high concen-trations of silicon were also found in the coker scrubber slop streams that were reprocessed at the pipestills. 79294-FOAMSTOP-antifoam-reduced-silicon-carryover-75%-saved-2.75million-over-17-months-cs.pdf
