13 Abstract of the Disclosure A separator apparatus and method for a hydrocarbon fluidized catalytic cracking process are disclosed. The apparatus comprises a main plenum in a disengagement vessel which connects a plurality of riser cyclones in a riser catalyst separation stage to a plurality of secondary cyclones in a secondary catalyst separation stage. The cyclones in the second and each succeeding stage receive a substantially equal amount of gas from the plenum. The effluent gas is substantially prevented from leaking into the interior space of the disengagement vessel. Also disclosed is a method for retrofitting an existing plant with the plenum design to provide a more compact arrangement of the catalyst separation equipment in the disengagement vessel.
