Abstract
An apparatus and method for contacting a fluid stream with particulate solids are provided. The apparatus comprises a vessel having an upper portion and a lower portion and an inlet for receiving particulate solids and an outlet for discharging the particulate solids. An inner cone is coaxially positioned within an inverted truncated outer cone forming an annulus in the lower portion of the vessel. A truncated conical baffle is disposed within the lower portion of the vessel and at least partially above the inverted truncated outer cone and the inner cone. The truncated conical baffle has a downwardly and inwardly sloping wall with a lower portion thereof overlapping interiorly an upper portion of the inverted truncated outer cone. A plurality of guide tents are spaced apart in the annulus, each guide tent having sloped guide surfaces oriented to guide the flow of particulate solids into the outlet.
