Exhaust Air Purification
If, in addition to the chemical cleaning of H2S, high demands are placed on the physical adsorption capacity at the same time, then good advice is usually rare. Both, doped and impregnated activated carbon can then often exhaust their potential just inadequately.
For these special applications, the activated carbon AFA 4- dot S was designed. It is produced on the basis of hard coal using the same patented process as the doped activated carbon dopetac sulfo 100®, and is characterized by a higher mesopore content. As a result, it is able to remove volatile organic compounds or siloxanes effectively from the gas phase, without significantly affecting the chemisorptive properties of the activated carbon.
Typical applications include, for example, adsorption processes in industry, exhaust air cleaning, waste fermentation plants, or facilities for cleaning landfill gas.
AFA 4- dot S is available in different big bag sizes or in handy paper bags of 20 kg.
