To resolve the persistent problem of
foaming in their processing units,
refiners commonly implement one or
more antifoam chemistries. In delayed
coker processes, traditional siliconebased
antifoams have been used for
many years due to their relative thermal
stability. However, the fractions of these
products that do thermally decompose
contribute silicon (Si) to the coker
product streams. When these streams
reach the hydrotreater, the silicon
shortens the operating life of the
catalyst, resulting in increased operating
costs and more frequent catalyst
replacements. FOAMSTOP-5025-antifoam-reduce-silicon-na-cs.pdf
