摘要
Disclosed is a method and apparatus for fluid catalytic cracking (FCC) of a hydrocarbon feed in an open or closed system, which includes a multistage stripper system. The multistage stripper system comprises a means for spinning a gasiform mixture of catalyst and cracked hydrocarbons exiting from a riser, a first means for stripping the spun gasiform mixture, and a means for deflecting the gasiform mixture to separate catalyst from the cracked hydrocarbons.
