ABSTRACT:
Effective quenching is provided in a catalytic cracking unit to increase product yield and decrease thermal cracking. Advantageously, the quench is injected at special locations. In the illustrated embodiment, the quench is injected into the oil product immediately downstream of the oil product exit of an internal gross cut separator in a disengaging vessel.
