Having decades of experience in the petrochemical und gas & oil industry, ANDRITZ delivers support grids and inlet / outlet filters in highest quality for gas adsorbers. Precise slot widths and thorough quality checks guarantee a stable and reliable process.

Support grids

The support grid is a retention device for the catalyst and extends over the entire cross section of the vessel. The catalyst is chosen for its efficiency, its stability, and selectivity. The required volume of catalyst is referred to the bed and extends over a fixed height for a given reactor diameter. The catalyst can consist of different types of material with varying size and bulk density. The catalyst layers may extend into one bed or several beds in a multi-bed reactor in such a way that  several support grids have to be installed in the same vessel.
