Abstract
A gas-solid fluidized bed is formed within a contacting element having pairs of planar portions arranged in intersecting planes, each planar portion being formed by one or more webs and one or more open slots adjacent each web, the webs and slots being arranged such that a web in one of the planar portions intersects a slot in the paired planar portion. The fluidized bed can be catalyst particles fluidized by a gas stream, such as in a catalyst stripper and/or regenerator in an FCC system.
Claims15
A gas-solid fluidized bed comprising:
- a container having a shell and an open internal region within the shell;
- a contacting device positioned within said open internal region and comprising pairs of planar portions arranged in intersecting planes, each planar portion comprising one or more webs and one or more open slots adjacent each web, the webs and slots being arranged such that a web in one of the planar portions intersects a slot in the paired planar portion;
- solid particles within the contacting device;
- and
- at least one gas stream flowing in a first direction through the contacting device and causing fluidization of the solid particles within the contacting device to form said gas-solid fluidized bed.
A process for fluidizing solid particles within a container having a shell and a contacting device positioned within an open internal region within the shell, said contacting device comprising pairs of planar portions arranged in intersecting planes, each planar portion comprising one or more webs and one or more open slots adjacent each web, the webs and slots being arranged such that a web in one of the planar portions intersects a slot in the paired planar portion, said process comprising the steps of:
- providing a quantity of solid particles within the contacting device;
- and
- causing fluidization of the solid particles within the contacting device by flowing at least one gas stream through the contacting device.
