ABSTRACT:
A process and apparatus for fluid catalytic cracking (FCC) of a hydrocarbon feed. The process and apparatus includes a riser which upwardly discharges into a deflector baffle located within a stripping vessel. The stripping vessel is located within a disengaging vessel. The deflector baffle is spaced from the riser and the stripping vessel. Preferably, the deflector baffle is shaped similarly to a large bubble cap. Catalyst passes downwardly from the baffle into a stripping zone within a lower portion of the stripping vessel. Hydrocarbons stripped from the catalyst pass upwardly away from the stripping zone, then pass to a cyclone located outside the stripping vessel and then discharge from the disengaging vessel.
