    摘要: Process for increasing mixing in a fluidized bed. A slide, which may be in the form of a tube or trough, transports particles from an upper zone downward to a lower zone at a different horizontal position, thereby changing the horizontal position of the particle and creating lateral mixing in the fluidized bed. Increased mixing may improve efficiency for an apparatus using a fluidized bed. For example, increased lateral mixing in a regenerator may increase temperature and oxygen mixing and reduce stagnation to improve efficiency. A slide may be relatively unobtrusive, inexpensive, and simple for a retrofit or design modification and may improve combustion efficiency at high rates by enhancing the lateral blending of spent and regenerated catalyst.

    摘要: A process for improving the yield of ethylene and propylene from a light naphtha feedstock includes obtaining light naphtha feedstock from a primary cracking zone having a cracking catalyst. The light naphtha feedstock is contacted with an olefin catalyst in an olefin producing zone to produce an ethylene- and propylene-rich stream. After reacting with the olefin catalyst, the ethylene- and propylene-rich stream is separated from the olefin catalyst from in a separator zone. At least a portion of the olefin catalyst is regenerated by combusting coke deposited on a surface of the olefin catalyst in an oxygen-containing environment, and at least a portion of the olefin catalyst is heated. These portions could be the same one or they could be different. In some embodiments, at least a portion of the olefin catalyst could be neither regenerated nor heated. The olefin catalyst is returned to the olefin producing zone.

    摘要: Cyclone separators and separator devices for separating gas and entrained particles from a particle-contaminated gas stream are provided. The cyclone separator comprises a cyclone body having a first end and a second end with a sidewall extending therebetween. The cyclone body defines a cyclone gas inlet for receiving the particle-contaminated gas stream. A cyclone gas outlet is for discharging the clean gas stream. A centripetal accelerator is proximate the cyclone gas inlet to induce centripetal acceleration of the particle-contaminated gas stream. The sidewall defines a discharge opening between the first end and the second end for discharging separated particles from the cyclone body. The discharge opening has a leading edge and a top edge in relation to a flow path of entrained particles within the particle-contaminated gas stream. The top edge extends at an acute angle relative to the leading edge.

    摘要: Disclosed is a process for disengaging regenerated catalyst from flue gas in a catalyst regenerator so as to avoid re-entrainment of catalyst that has settled into a bed in the catalyst regenerator using a disengaging device. A disengaging arm of the disengaging device has an outer shell that encloses the arm, an inner shell with a slot for allowing catalyst and flue gas to exit the arm and an outer baffle having a lower edge located below the opening in the outer wall. The baffle directs the catalyst and flue gas downwardly and limits radial flow. Catalyst and flue gas enter the disengaging arm through an opening in an outer wall of a riser section at a first superficial velocity and exits through a slot in a bottom of the disengaging arm at no more than 1.33 the first superficial velocity.

    摘要: In at least one embodiment of the present invention, a method of recovering energy from a FCC unit having a reactor and a regenerator for overall CO2 reduction is provided. The method comprises cooling syngas to a predetermined low temperature to define cooled syngas. A turbo-expander including a first compressor is provided. The turbo-expander train is configured to combust and expand gas to drive the first compressor. The cooled syngas is compressed with the first compressor to define compressed syngas. A first stream of gas comprising CO2 and a second stream of gas comprising CO are separated from the compressed syngas. O2 and the first and second streams of gas are introduced to the turbo-expander train. The first stream of gas is expanded and the second stream of gas is combusted and expanded with the O2 to recover energy, driving the first compressor and producing the syngas.
