    摘要： Integration of gas oil and light olefin catalytic cracking zones with a pyrolytic cracking zone to maximize efficient production of petrochemicals is disclosed. Integration of the units in parallel allows production of an overall product stream with maximum ethylene and/or propylene by routing various feedstreams and recycle streams to the appropriate cracking zone(s), e.g. ethane/propane to the steam pyrolysis zone and C4 C6 olefins to the light olefin cracking zone. This integration enhances the value of the material balances produced by the integrated units.

    摘要： A method of converting an original FCC unit of side by side configuration to a converted FCC unit for processing light feedstock by replacing an regenerator in the original FCC unit with an embodied regenerator. From the original FCC unit, the air supply assembly is removed and a centerwell is installed with a fluidization gas, fuel, and air inlet(s) through the centerwell. Distribution rings are connected to each of fluidization gas and fuel inlet(s). An internal pipe and a standpipe portion are installed, wherein a lower end of the standpipe extends into the centerwell creating a radial slot, and wherein the lower end of the standpipe is spaced above the deflector plate in the centerwell to allow flow of spent catalyst through the standpipe and provide deflection of the spent catalyst flow for mixing the spent catalyst with fuel oil that is vaporized within the centerwell.

    摘要： A catalyst regenerator for regenerating spent light FCC catalyst and heating the catalyst to supply heat to an FCC reactor. The regenerator has discharge outlets for catalyst and off gas and a valve for introducing spent catalyst through a central stand pipe portion. The regenerator houses a dense phase catalyst bed. A centerwell receives a lower end of the standpipe portion and defines an annulus therebetween. The spent catalyst is introduced through the standpipe portion into the annulus. A fuel distributor introduces fuel into the centerwell for mixing with the catalyst in the annulus. A fluidization distributor introduces fluidization gas into the centerwell for fluidizing the catalyst in the annulus. A radial slot in the centerwell introduces the catalyst and fuel mixture from the annulus below the upper surface of the dense phase bed. An air distributor located below the radial slot introduces combustion air into the dense phase bed.
