  • Patent number: 10273417
    Abstract: An apparatus which is an integral hardware consisting of an annular downer reactor and a concentric upflow riser regenerator for catalytic cracking of hydrocarbon feed to is disclosed. The annular downer reactor terminates in annular stripper which is also concentric with the regenerator. The regenerator, reactor and stripper are in fluid connection with each other. The apparatus is highly compact and provides efficient contact between circulating catalyst and hydrocarbon feed. The proposed hardware includes a novel radial distributor for providing improved control and radial distribution of catalyst inside the downflow reactor. The radial distributor has equal numbers of stationary and movable parts placed one after another to cover the entire annular opening at the bottom of the regenerated catalyst vessel. The radial distributor is concentric with regenerator and located between the catalyst holding vessel and the reactor. A process for catalytic cracking using the invented apparatus is also disclosed.

  • 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: 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.
