Abstract:
A process of injecting a substantially linear array of feed jets comprising at least partially liquid phase hydrocarbon compounds and a gas into a stream of fluidized particles, said method comprising:dividing a central stream of hydrocarbon compounds into a plurality of uniform hydrocarbon substreams;dividing a central stream of said gas into a plurality of uniform gas substreams equal in number to the said hydrocarbon substreams;combining each of said gas substreams with one of said hydrocarbon substreams to provide a plurality of combined streams each carried by a conduit;mixing gas and hydrocarbon compounds in said conduits to produce a fluid mixture;discharging a jet of said fluid mixture from the end of each conduit through a fluid nozzle into a contacting vessel to produce a horizontal pattern of atomized liquid discharged from an essentially linear array of jets;passing a dispersion of catalyst particles through said contacting vessel in a catalyst flow pattern that is in the form of a substantially vertical falling curtain and primarily flat;directing each of said jets substantially horizontally toward said catalyst flow pattern in a direction perpendicular to said catalyst flow pattern and into a different portion of said catalyst flow pattern; andsupporting an outer length of the conduit from an outer end of a containment shroud that surrounds all of said conduits and fixing an inner length of the conduit or nozzle to an inner end of the containment shroud wherein the containment shroud extends into said contacting vessel.
