ABSTRACT:
A method and apparatus for improving the separation of a catalyst phase from a gas suspension phase in a fluidized catalytic cracking (FCC) unit. In a vertical separation embodiment, a cyclone separator inlet is located in the upper portion of a riser conversion zone and draws off gaseous hydrocarbon materials, while catalyst particles continue vertically to the end of the riser conversion zone, and pass through a catalyst conduit to a catalyst storage area. In a horizontal separation embodiment, the catalyst/hydrocarbon mixture is transported horizontally from the end of the riser conversion zone past a cyclone separator inlet towards a catalyst conduit. The cyclone inlet draws off gaseous hydrocarbon materials, while the catalyst particles pass through the catalyst conduit to a catalyst storage area.
