ABSTRACT:
In this invention a cyclonic separation apparatus discharges particulate solids and gaseous fluids into a separation vessel from a discharge opening of a central conduit and withdraws separated gaseous fluids from the separation vessel that contacts the catalyst in the separation vessel with redistributed gases from outside the separation vessel. The invention increases the effective utilization of available stripping medium in an FCC process.
