Patent number: 10150054Abstract: A packing system is disclosed that has a series of flat blades arranged to promote mixing in a fluidized bed such as one in a FCC stripper, with an upward flowing gas stream and a downward flowing solid particle stream. The blade arrangement provides for different gas solids flow directions within a single layer of packing system to enhance cross mixing of gas and catalyst in all directions and reduces the potential for gas and catalyst bypassing. The blade arrangement has splits which minimizes the tendency for phase separation around the blade. The arrangement and sizing of the blades is intended to promote intimate contact between the two phases to ensure efficient mass transfer of material trapped inside the particles to the gas phase. The arrangement of the blades prevents excessive bubble growth and channeling, both of which reduce surface area for mass transfer.Type: GrantFiled: November 30, 2017Date of Patent: December 11, 2018Assignee: Technip Process Technology, Inc.Inventors: Paul Marchant, Raj Kanwar Singh
