A refiner was treating their coker with BPR45000 antifoam that was contributing 3,500 lb (1,588 kg) of silicon per year carryover to downstream units. The refiner was experiencing an increase in the silicon content of incoming crudes, resulting in rapid contamination of their downstream catalysts. They agreed to trial FOAMSTOP™ low catalyst impact (LCI) antifoam to address the problem. This patented product contains a proprietary agent that is more thermally stable than conventional silicone oils. A temporary tote injection system was installed to allow feeding of the trial antifoam and provide ease of switching back to the old antifoam if needed.
