Column Internals : Simple Grid Support
Simple Grid Support with an open area of 75-80%.Pressure drop estimated at .45" WC.
Design permits installation through manway, size to be specified by column designer, normally 24". All necessary assembly hardware included.
Grid supported by circumferential ring furnished as integral part of the column.Grid may be self supporting.Lantec will advise if addional support beams are required
For holding the packing in the column,NAIKE Chemical manufactures a variety of support grids specially designed for different applications and column diameters.
For the design of the specific grids, the following points must be considered with regard to the load of the grid:
Weight of packed bed
Liquid hold up during operation
Pressure drop of the gas flow in cases of parallel flow
The support grid has to be constructed in a way that allows the unrestricted flowing of gases and liquids in the columns as much as possible. There is the possible complication of blocking the gas flow with unsuitable packing support, especially in the area between the support grid and the packed bed.
For the installation of the support grid there is a support ring, and from case to case, one or more intermediate support beams as necessary. Usually it is sufficient to put the support grid on the support ring without fixing it; however, for applications with high gas velocities, pressures, or flooding possibilities it is necessary to fix the support grid to the support ring.
