초록 ▼

An apparatus for fluid catalytic cracking (FCC) of a hydrocarbon feed in an open or closed system, which includes a multistage stripper system, which comprises a means for spinning a gasiform mixture of catalyst and cracked hydrocarbons exiting from a riser, a first means for stripping the spun gasi

대표청구항 ▼

A fluid catalytic cracking apparatus comprising: a reactor vessel; a confined vessel; a riser conversion zone defined by a vertically disposed elongated tubular conduit having an upstream end and a downstream end; said downstream end of said riser located within an upper portion of said confined vessel and said confined vessel located within said reactor vessel; means for introducing hydrocarbon feed and catalyst into said upstream end of said riser conversion zone to produce a gasiform mixture of catalyst and cracked hydrocarbons existing at said downstream end of said riser conversion zone; means for spinning said mixture, at said downstream end of said riser conversion zone, around the longitudinal axis of said riser conversion zone, said spinning means being located within and adjacent said riser downstream end and comprising means defining an annular space in said riser provided with a plurality of fixed spaced apart sloping baffles for spinning said catalyst; means defining a first catalyst stripping zone, located within a lower portion of said confined vessel; means for admitting stripping gas, into said first stripping zone, for contacting with said catalyst in said mixture and for directing hydrocarbon vapors upwardly to promote separation of said catalyst from said hydrocarbon vapors; means for downwardly deflecting said spun catalyst to said first catalyst stripping zone, thereby separating a major portion of said catalyst stripping said cracked hydrocarbons, said deflecting means being located within said confined vessel; and an extension means attached to each of said baffles for guiding said spun catalyst to said deflecting means.
