Abstract
The present invention is concerned with the cooling of the fluidizable particulate solids, either catalytic or inert, in the regenerator section of an FCC process, an RCC process or a metals removal systems or 'ART' type process. It is directed to the use of a conduit means for charging fluidizing gaseous material to a vertical cylindrical vessel for cooling fluidizable particulate solids flowing through said vertical cylindrical vessel, which conduits means comprises a horizontal header means having suspended therefrom a plurality of vertical and horizontally spaced apart conduits, each conduit having near its open end a restriction orifice. The header means can be located near the top of the cylindrical cooling vessel. While the example of a specific embodiment discloses one portion of the vertical conduits with lower ends located in a lower cross-sectional area of the vessel other arrangements sufficient to ensure proper fluidization are also possible.
