ABSTRACT:
Catalyst and hydrocarbon vapors are separated in separator-stripper vessel by a reverse flow separator assembly in a top portion of the separator vessel. The separator assembly contains a shrouded eductor where the particles and gas enter the eductor, and upon exit the gas reverses direction to travel through the passage between the eductor and the shroud, thus causing disengagement of the particles. The gas free of particles then passes out the vessel exit and the particles return to the particle bed in the lower portion of the vessel.
