    摘要: A compact dual stage cyclone separation assembly, an efficient dual stage cyclone separator, and a method for utilizing the same, comprising a lower pressure drop across the dual stage separators due to fewer particle-contaminated gas flow directional changes in the particle contaminated gas stream, and method for using same. The dual stage cyclone separator comprises a primary stage cyclone barrel and a second stage cyclone barrel, wherein the second stage cyclone barrel is coaxial with and concentric within the first cyclone separator, a solids extraction port, wherein said sidewall of said main body defines a solids extraction port opening located between said upper end and said lower end for discharging large particles from said cyclone body, and a small particle discharge opening, wherein the small particle discharge opening is located inside the lower end of the main body.

    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: A process and apparatus for improving flow properties of crude may include processing a first crude stream, which may in turn include cracking the first crude stream with catalyst to form a cracked stream and spent catalyst, hydrotreating a portion of the cracked stream and then mixing the hydrotreated stream with an unprocessed second crude stream.

    摘要: Embodiments of a gas-solids separation unit and embodiments of a method for manufacturing a separation unit are provided. In one embodiment, the separation unit includes a cyclonic separator and a vessel having a flue gas chamber, a clean gas chamber, and an entrained solids chamber between the flue gas chamber and the clean gas chamber. The cyclonic separator includes, in turn, a cyclone barrel extending from the flue gas chamber toward the clean gas chamber, a swirl vane positioned across the cyclone barrel, a gas outlet tube fluidly coupling the cyclone barrel to the clean gas chamber, and a first check valve opening formed through the barrel sidewall upstream of the gas outlet tube. The check valve opening fluidly couples the cyclone barrel to the entrained solids chamber to permit the centrifugal separation of the particulate matter from the gas stream during operation of the gas-solids separation unit.

    摘要: Disclosed is an apparatus and 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.
