Trays for distillation columns

Sulzer has a wide range of trays for distillation columns and can thus deliver and guide you to the best solution. Their technologies include the following:

Column internals

VFF is specialized in supplying equipment for columns such as liquid distributors, grids, support plates and gas distributors.

Liquid 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.

Applications:

Flame traps
Evaporators - distillation and rectification installations
Gas washers for other uses
Air and gas washers
Sound absorbers

Oil separators
Foam separation
Separation of liquid from liquid (coalescences)
Equipment for seawater desalination - sulphuric acid plants
