With chemical absorption, an ion, atom or molecule is absorbed into the free volume of the absorbing phase. The process of gas scrubbing is used, among other things, for the treatment of industrial waste gases or for the removal of odours. As an absorbent, water is used and – depending on the pollutant – the addition of specific chemicals (chemisorption) takes place. In most cases, very high treatment performance is achieved.
To achieve the required treatment performance at low operating costs. We designs and manufactures various kinds of scrubbing types for different applications such as
- Counter-flow scrubber
- Cross-flow scrubber
- Direct-flow scrubber
They can be installed in one or more stages or can be used as emergency units.
In addition to scrubbers, We offers activated carbon filters for the adsorption of air pollutants. Activated carbon is fine-grained carbon with a highly porous structure and a very large surface. By attachment on the inner surface of the activated carbon, harmful or odorous substances are removed from gases, vapours and liquids.
In activated carbon filters, They can be used to eliminate a wide range of harmful or odorous substances such as
- Hydrogen sulphide
- Indole and skatole
Waste Gas Treatment — Pyrolysis
The process waste gases are burnt in a decomposition zone. If required, a fuel gas can be applied. Depending on the chemical composition of the waste gases, various reactions take place, such as oxidation, reduction or pyrolysis.
Wet Scrubber Treating Water-Soluble Substances
Wet scrubbing is an efficient process for the treatment of water-soluble pollutants in process exhaust gases. Our wet scrubbers are employed mainly in the semiconductor industry wet treatment system. Installed closely behind the vacuum pumps, they optimally protect the fab’s exhaust gas system from contamination and corrosion. Maintenance is quick and easy.
