VFF column materials
Short delivery times
As the largest manufacturer of column materials in Europe, VFF is able to respond to requests within the shortest possible time.
VFF offers hydraulic calculations for random packings and demisters, e.g. specific pressure loss, flood factor and other important key figures for the operation.
VFF is specialized in supplying equipment for columns such as liquid distributors, grids, support plates and gas distributors.
To obtain an effective column it is important to have a good liquid distribution ensuring an even liquid concentration across the column. VFF makes customized solutions which will suit your column perfectly, and they offer liquid distributors made from a wide range of materials such as ceramics (ACIDUR® special stoneware), metal (C-steel, stainless steels, alloys and others), plastic (PE, PP, PVC, C-PVC, PVDF, PTFE and others).
Grids and support plates
Customized grids and support plates can be supplied in a wide range of materials such as ceramics (ACIDUR® special stoneware), metal (steel, stainless steels, alloys and others) or synthetic materials (PE, PP, PVC, C-PVC, PVDF, PTFE and others).
Demisters (droplet separators)
We at Aage Christensen are specialized in supplying equipment for columns such as droplet separators.
The principle behind a droplet separator is that small drops collide with the droplet separator consisting of a wire surface after which they run together in the junctions and return to the container as larger droplets. The separation efficiency, which is affected by the free volume and the specific surface area of the wire mesh, is improved as the flow velocity increases. A too high gas velocity may result in penetration of droplets.
Based on the operating conditions and on the demistor type a precise calculation of all important operating variables such as allowed velocity, pressure drop and separation efficiency is made.
