Device for stiffening plates of multi-stage column such as simulated moving bed separation column, comprises beams located beneath the plates, which support a bed of solid particles and are crossed downwards by flowing of fluid
The device comprises beams located beneath the plates. Each plate supports a bed (2) of solid particles, and is crossed downwards by flowing of fluid. Each beam has a profiled triangular lower surface. An angle (theta ) of two equal sides of profiling in triangle with respect to horizontal is 25-35[deg] . The profiled beams are: divided into a main beam aligned along a diameter of the column and secondary beams perpendicular to the main beam; parallel; and aligned along shelves. The solid particles constituting granular bed have a diameter of 300-800 microns. The device comprises beams located beneath the plates.
