Abstract

The interzone mixing device of the present invention is positioned in a multi-zoned vessel for flow of fluid generally vertically therethrough. The interzone mixing device includes a horizontally disposed first plate that has a central opening in it and a cylindrical cap extending upwardly from the first plate and sized and positioned to cover the central opening therein. The cap has a plurality of angular slots in the side wall to direct the flow of fluid passing therethrough in a swirling direction toward the central opening in the first plate. The interzone mixing device also includes a horizontally disposed second plate which has a plurality of openings in an annular ring around the periphery of the second plate. Additionally, a horizontally disposed circular table is positioned on the second plate and is aligned with the central opening in the first plate. A third horizontally disposed plate, having a central opening therein, is spaced apart from the second plate and defines a jet stirred mixing zone therebetween. A horizontally disposed fluid distribution plate is spaced apart from the third plate. A conduit for introducing a quench fluid is also provided in this apparatus.
