Abstract:
1. An apparatus for separating catalyst particles from a gaseous product stream comprising: an elongated riser in which a hydrocarbon feed is contacted with catalyst particles to produce a gaseous product, said riser including a swirl outlet configured to induce the solid catalyst particles and gaseous product stream to swirl in an angular direction to disengage catalyst particles from said gaseous product; a disengaging vessel communicating with said swirl outlet of said riser, said disengaging vessel including an outer wall and a lower stripper section comprising elongated strips; a cyclone in downstream communication with said swirl outlet for further separating said catalyst particles from said gaseous product; and a baffle disposed below said swirl outlet and above said stripper section in said disengaging vessel for directing catalyst particles away from the outer wall of said disengaging vessel so catalyst particles can begin their descent through the elongated strips toward the center of the stripper section to assure the catalyst particles contact the full range of elongated strips.
