Embodiment 1

[0037] A series of different packing elements were tested in a cold hydrodynamic column to determine the stripping efficiency of stripping helium from an FCC equilibrium catalyst using air. Two embodiments of the contacting element of the present invention were tested in which the baffle sections 14 were arranged at an angle of 60 degrees to the vertical axis of the column. In the first embodiment, the staggered baffle sections 14 form a diamond shape having a height of 7.5 inches and a width of 4.33 inches. The corresponding dimensions of the second embodiment are 5.0 inches high and 2.88 inches wide. Contact elements were tested against corrugated plates having a bead height of 2.5 inches with a corrugation angle of 60 degrees and conventional disc and ring trays. The test results were then analyzed using a staged efficiency model in which one disc or annular tray corresponds to one stage. The results of the analysis are attached image 3 , from which it can be seen that ...

Abstract

A gas-solid fluidized bed is formed within a contacting element (10) having pairs of planar portions (14) arranged in intersecting planes, each planar portion (14) being formed by one or more webs (16) and one or more open slot s (18) adjacent each web, the webs (16) and slots (18) being arranged such tha t a web in one of the planar portions (14) intersects a slot (18) in the paire d planar portion. The fluidized bed can be catalyst particles fluidized by a g as stream, such as in a catalyst stripper and / or regenerator in an FCC system.

Description

Background of the invention [0001] This invention relates generally to fluidized beds in which solids and liquids flow in countercurrent, and more particularly to the use of internal structures to facilitate contact of solids and liquids in a fluidized bed. [0002] Fluidized beds are frequently used in petroleum, chemical, combustion, and other types of processes to promote the intense mixing and intimate contact of liquid streams and solid particles in vessels that can be used to obtain efficient heat, mass, and / or A liquid stream, a chemical reaction between solid particles and / or coating or entraining a liquid on solid particles. A fluidized bed is typically produced by passing a stream of liquid, usually vapor, upwardly through a bed of small solid particles at a rate sufficient to suspend the particles and create turbulent mixing of the solid particles. The lower boundary of the fluidized bed is formed at or just below the level of the liquid stream inlet and the upper ...
