Definitions

  • Cyclones usually comprise a tangential inlet to the outside of a cylindrical vessel that forms an outer wall of the cyclone.
  • the cyclone entry and the inner surface of the outer wall cooperate to create a spiral flow path or vortex of the gaseous materials and catalyst in the cyclone.
  • the centripetal acceleration at the exterior of the vortex causes catalyst particles to migrate towards the outside of the banel while the gaseous materials enter an interior of the vortex for eventual discharge through an upper outlet.
  • the heavier catalyst particles accumulate on the side wall of the cyclone barrel and eventually drop to the bottom of the cyclone and out via an outlet and a dipleg conduit for recycle through the FCC apparatus.
  • FIG. 3 The orientation of curvature of swirl arms 114 is shown in FIG. 3.
  • a mixture containing particulate material and gaseous fluids ascending through reactor riser 12 exit the reactor riser 12 through swirl arms 114 out discharge opening 16 swirling in a clockwise angular direction.
  • the mixture will retain the same swirl motion in a clockwise angular direction.
  • FIG. 5 The section at segment B-B of FIG. 1 that conesponds to the embodiment illustrated in FIG. 7 is illustrated in FIG. 5.
  • Swirl arms 14 impart a swirl motion of counter-clockwise angular direction "F" to the mixture containing particulate material 50 discharging from the reactor riser 12. This counterclockwise angular direction "F” of swirl motion continues as the mixture travels up gas recovery conduit 18.
  • the mixture exits the gas recovery conduit 18 through cyclone inlets 230 which are substantially tangential to the gas recovery conduit 18.
  • the mixture enters each cyclone 22 through a tangential cyclone inlet 230 defined by long, straight sidewall 234 and short, straight sidewall 236.
