Effective Air & Gas Purification with Activated Carbon

Flexible solutions with granulated, powdered and impregnatied activated carbons

More stringent regulations in emission control and for the quality of gases of all kinds require efficient processes and materials that can meet the constantly growing requirements.

With a variety of special properties that go beyond its prominent inner surface, activated carbon is therefore used in countless applications. As the final or only necessary purification stage, it provides clean air and pure product gases.

Coarse-grained and extruded carbons are primarily used for this purpose. This way, maximum removal efficiency can be combined with the lowest possible pressure loss.

With the Alcarbon®, Desorex®, Supersorbon® and Oxorbon® product lines, Donau Carbon offers activated carbons designed specifically for your applications.

In the field of air and gas purification, it could be for example one of the following:

• Exhaust air: Odour control, Reduction of total Carbon

• Exhaust gases: Removal of solvents / VOCs, ammonia

• Biogas & sewage gas: Fine cleaning (H2S, NH3, siloxanes)

• Natural gas: Removal of BTEX, H2S, mercaptans, odorants

• Industrial gases: Purification of CO2, H2, syngas, process gases (BTEX, H2S, COS)

• Solvent recovery: Efficient materials for various solvents

• Flue gas treatment: Removal of dioxins/furan, mercury, heavy metals

• Tank breathing: Capturing fuels and solvents

How do I fulfil Specific Requirements?

Increasing quality and environmental standards can be realiably maintained with activated carbon

Compliance with legal requirements has top priority: Donau Carbon‘s products offer a suitable solution for (almost) every task and challenge.

Exhaust air & waste gas treatment
Facilities that generate emissions and odours, such as waste sorting plants, paint shops or the chemical industry, require appropriate measures to comply with official limit values, e.g. in accordance with Directive (EU) 2016/2284 or Directive 2008/50/EC.

The use of activated carbon(s) often offers the most effective and at the same time most economical solution, for both temporary and permanent use.

Biogas
In order to achieve feed-in quality, a final polishing step is necessary for biomethane. Depending on the raw material / process, the present impurities (H2S, NH3, siloxanes) can be removed reliably and cost-effectively using suitable activated carbon.

CO2 purification
For carbon dioxide to be used e.g. in beverage industry, several purification steps are required to achieve the strict quality specifications, depending on the source of the gas. In addition to typical organic components, other gaseous impurities such as ammonia, hydrogen sulphide or carbonyl sulphide can be safely removed down to the lowest concentration ranges, using various impregnated activated carbons.

Quality Assurance

In our in-house laboratories, activated carbons are evaluated and tested for the most important characteristics in air and gas purification, including

• Grain size (mesh / mm)

• Butane activity (BA) / CTC value

• Benzene adsorption

• Apparent density / Bulk density

• Hardness (wt.%)

Certificates

Donau Carbon offers relevant certificates such as

• ISO 9001:2015

• ISO 14001:2015 for our production in the Philippines
