Support Plates in Metal and Plastic

The main function of a support plate is to bear the packed bed. In addition to this, it must also meet other requirements.

High degree of permeability for both gas and liquids.

High degree of stability with low own weight.

Availability in various types of material to suit different corrosion levels.

Easy installation in the column (segment construction).

The flat bar plates and perforated plates used in the past possessed distinct disadvantages. The free cross-sectional area of the plates was too small and was further reduced by the tower packings on top. In order to achieve the necessary stability, the plates often had an extremely high own weight.

The development of modern types of support plate for different kinds of materials has ensured that the requirements listed above can be fulfilled.

The Multibeam support plate is available for use with metal and plastic tower packings; this plate works on the gas injection principle and has proven its worth in operation. One of the types used for tower packings made of plastics is the patented RASCHIG SUPER GRID .

For structured packings, a flat bar support plate, designed to fit the packing segments, is used.
