Abstract
A particular aspect of the invention concepts disclosed and described is directed to the use of a vented cup ballistic separation device and method of use for achieving rapid separation of a suspension of fluidized solid particulate and gasiform material. The vented cup ballistic separation apparatus is particularly discussed in conjunction with separating a suspension of catalyst particles from vaporous hydrocarbon reaction products of catalytic cracking discharged from a riser cracking operation. The vented cup ballistic separation apparatus particularly comprises an annular chamber about the upper periphery of an open ended riser conduit. The annular chamber is open in the upper end and one or more open end conduits extend outwardly from the annular chamber comprising means for attachment to cyclone separation means. The riser with vented cup or annular chamber terminates within a larger diameter chamber.
