Abstract
Disclosed are methods and systems for removing reactive carbonyl monomers which can polymerize to produce red oil. In an embodiment the method may include cracking a hydrocarbon stream in a fluidized catalytic cracker to produce a cracked hydrocarbon stream comprising carbonyl compounds; separating hydrocarbon components from the cracked hydrocarbon stream in a debutanizer column to form a debutanizer overhead LPG stream comprising the carbonyl compounds; introducing the debutanizer LPG overhead stream into a carbonyl removal unit comprising a metal bisulfite bed; reacting the carbonyl compounds in the debutanizer overhead LPG stream to form a carbonyl adduct with the metal bisulfite; and withdrawing a first LPG product stream from the carbonyl removal unit.
