  • Patent number: 9636652
    Abstract: Vessel and support beam assembly includes a vessel having a cylindrical wall defining an interior chamber having a generally circular shape of diameter D in plan view, and a support assembly disposed within the interior chamber. The support assembly includes an inner hub defining an open central region, and a plurality of spokes extending radially from the inner hub. Each spoke is aligned radially with the cylindrical wall of the vessel and joined thereto. At least one open outer region is defined between circumferentially adjacent spokes.

  • Patent number: 9440212
    Abstract: Integrated primary and secondary cyclone assembly includes a secondary cyclone having an outlet tube extending therefrom and a primary cyclone operatively coupled with the secondary cyclone. The outlet tube has a cross dimension and length and is configured to be secured to a pressure vessel closure head to support the secondary cyclone therefrom. The primary cyclone has a tubular support member extending therefrom. The tubular support member is aligned substantially parallel with and has a length similar to the outlet tube of the secondary cyclone and is configured to be joined to the pressure vessel closure head to support the primary cyclone therefrom.

  • Patent number: 9266123
    Abstract: Integrated cyclone stabilizer assembly includes an upper annular ring to be disposed at an upper portion of the cyclone, a lower annular ring to be disposed at a lower portion of the cyclone, and a plurality of struts extending between the upper annular ring and the lower annular ring. The upper annular ring has a plurality of hinge members extending radially therein to support the upper portion of the cyclone therefrom. The lower annular ring has a plurality of hinge members extending radially therein to support the lower portion of the cyclone therefrom. Cyclone assembly include a primary cyclone, a primary cyclone assembly, a secondary cyclone and a secondary cyclone assembly. At least one connecting member couples at least one of the upper and lower rings of the primary stabilizer assembly to a corresponding annular ring of the secondary stabilizer assembly.

  • Patent number: 9162206
    Abstract: Reactor bed component includes a foundation grate, a rigid structure and a fastener. The foundation grate has support plates spaced apart from each other by a distance and having a height with each support plate disposed at an angle. The rigid structure has first structure plates spaced apart by a multiple of the distance and disposed at the angle, and second structure plates secured to and disposed at an opposing angle. Each second structure plate has a horizontal extent to engage an upper edge of a corresponding support plate, and a number of the first structure plates have a length extending below the horizontal extent in overlapping relation with adjacent support plates to prevent horizontal movement of the rigid structure relative the foundation grate in a first direction. The fastener is disposed to secure the rigid structure to the grate against movement in a second direction opposite the first direction.

  • Patent number: 8728302
    Abstract: The present invention relates to an improved design for use in fluid cracking processes, preferably used in either a fluid catalytic cracking (“FCC”) process or a fluid coking process. In particular, the present invention relates to an apparatus and process for improving the separation and distributing spent catalyst and gases in a spent catalyst riser associated with a fluid cracking process, and most preferably for use in a spent catalyst riser associated with an FCC regenerator vessel. A novel catalyst distributor design and associated processes are presented herein which significantly improve combustion in the dense-phase fluidized catalyst bed of a regenerator and results in improved regenerator dense bed combustion and lower migration of oxygen into the regenerator overhead region.
