  • Patent number: 10266459
    Abstract: A process and apparatus for catalytic cracking of hydrocarbon feedstock employing circulating fluidized bed reactor-regenerator configuration for maximizing the yield of propylene (C3 olefin) is disclosed. The apparatus comprises two reaction zones operating under different temperature and weight hourly space velocity (WHSV), one primary zone for cracking of hydrocarbon feedstock and other as secondary zone for cracking of C4 fraction produced from the cracking of hydrocarbon feedstock in the primary reaction zone, optionally admixed with C4 stream from external source. Two dedicated conduits equipped with valves for control of catalyst flow rate are provided to supply the hot catalyst from a common catalyst regeneration zone wherein the catalyst flowing though conduit connected to the secondary reaction zone is cooled employing a heat exchanging device.

  • Publication number: 20190011126
    Abstract: An apparatus and a method for achieving progressive reduction of flue gas is disclosed. Accordingly, an aspect of the present invention is to provide an apparatus comprising of an orifice chamber having an inlet pipe for receiving the flue gas, a flow region defined downstream of an exit of the inlet pipe and having at least a first section and a second section, and an outlet pipe to disperse a pressure reduced flue gas. The first section defined downstream of the inlet pipe has a flow developer means and at least one auxiliary orifice plate. The second section defined downstream of the first section has a plurality of orifice plates spaced apart along a flow length of the second section.

  • Publication number: 20190001353
    Abstract: An apparatus and a method for mixing and atomizing a hydrocarbon stream is disclosed. The apparatus comprises of an inner conduit having a first inlet for receiving the hydrocarbon stream, and a second inlet for receiving a primary dispersion stream. The inner conduit produces a primary mixture comprising the hydrocarbon stream and the primary dispersion stream. The apparatus further includes an outer conduit having a third inlet for receiving a secondary dispersion stream. Further, said inner and outer conduits together define an annular passage. The distal end of the annular passage defines a second set of orifices for allowing the secondary dispersion stream flowing there-through to come in contact with the primary mixture and thereby dispensing the secondary mixture so obtained through an outlet.

  • Publication number: 20180345267
    Abstract: According to an embodiment, a spent catalyst distributor for distributing spent catalyst in a catalyst regenerator vessel housing a dense phase catalyst bed and a dilute phase catalyst bed is disclosed. The spent catalyst distributor comprises a conduit comprising a proximal end and a distal end. The conduit projects horizontally or horizontally and downwardly into the regenerator vessel and includes an opening located at the distal end for introducing the spent catalyst at a first location inside the regenerator vessel. The conduit further includes a plurality of orifices located along a length of the conduit between the distal end and an inner wall of the regenerator vessel for introducing the spent catalyst at a plurality of locations inside the regenerator vessel.
