  • Patent number: 10576443
    Abstract: A regenerator for an FCC apparatus. The regenerator includes an internal riser inside of a outer shell. The internal riser includes a cone and a cone skirt. An annulus is formed between the internal riser and the outer shell. A sealing apparatus for keeping catalyst out of a portion of the annulus comprises a first sealing element and a second sealing element disposed above the first sealing element. An annular trough in the annulus below the primary seal is filled with material that has a heat transfer coefficient at least as high as air to allow heat to get to the inner surface of the outer shell.

  • Patent number: 10458329
    Abstract: A power generation process for use in a processing unit that includes the steps of: using a regenerator to produce a flue gas stream; removing catalyst particles from the flue gas stream; routing the flue gas stream to a combustor/expander unit after performing the step of removing catalyst particles; and using rotation of the turbine of the combustor/expander unit as a source of rotary power. Preferably, the combustor/expander unit includes a combustion chamber and a power recovery turbine housed within a single casing. In certain embodiments, the flue gas stream is routed between the regenerator and the combustor/expander without passing through a compressor.

  • Patent number: 10040045
    Abstract: Apparatuses and methods for separating regenerated catalyst are provided. In one embodiment, an apparatus for separating regenerated catalyst includes a regeneration vessel including a catalyst bed section. The apparatus includes a catalyst settler physically separated from the catalyst bed section by a wall extending within the regeneration vessel. The catalyst overflowing the catalyst bed section flows over the wall and enters the catalyst settler. The apparatus further includes a pipe in fluid communication with the catalyst settler and configured to deliver regenerated catalyst from the regeneration vessel to another vessel.

  • Patent number: 10016753
    Abstract: A baffle is installed on the wall of a regenerator vessel to push catalyst away from the wall to ensure adequate exposure to regeneration gas and complete combustion of coke from the catalyst. We have found that in deep beds, catalyst can flow down the walls and escape sufficient exposure to regeneration gas and undergo too little regeneration.

  • Patent number: 9873641
    Abstract: A process and device for the flow of catalyst in a reactor is presented. The device includes a series of grids within a reactor vessel, where each grid includes small openings for the passage of gas and some catalyst particles, and larger openings for the more continuous passage of catalyst. The grids span horizontally across the vessel, and are spaced vertically apart to provide for the flow of catalyst down through the reactor.

  • Patent number: 9702542
    Abstract: A co-generation process for a regenerator in an FCC system having a reactor and a regenerator includes the steps of introducing flue gas from the regenerator into a heating unit at a first location of the heating unit, and introducing an oxygen/fuel gas mixture into the heating unit at a second location of the heating unit apart from the first location, and combusting the oxygen/fuel gas mixture in the heating unit at the second location to form a hot combustion gas. The process further includes the steps of combining the hot combustion gas and the flue gas at a third location of the heating unit apart from the first location to produce heated flue gas, heating water and/or steam with the heated flue gas to produce a heated steam, and introducing the heated steam into a turbine to extract energy from the heated steam.

  • Patent number: 9670421
    Abstract: An apparatus and process is disclosed for mitigating coking in an FCC reactor plenum. The apparatus and process utilize a baffle to create a inner volume for the product vapors to prevent contact with a relatively cool plenum. The baffle also limits the amount of the time the product vapors spend in the plenum minimizing time for coke formation and limit product vapors from entering low fluidization zones.

  • Patent number: 9233885
    Abstract: A process and apparatus is presented for the improved selectivity of oxygenate conversion to olefins. The process includes passing a process stream through a two stage reactor, wherein the process stream is separated from the catalyst in the first stage before passing the process stream to the second stage. The catalyst is continuously passed through the two stages, and cycles through a regeneration unit to control the carbon content on the catalyst.
