Activated carbon - Import export

Adsorption plants are an efficient way of filtering VOC (volatile organic compounds) or other pollutants from exhaust air, flue and exhaust gases in industrial and municipal applications. In comparison to absorption processes, in which harmful substances are bound by the use of liquids, an adsorption plant concentrates the pollutants These are physically attached to an adsorbent such as zeolite or activated carbon. The adsorption process is efficient and costeffective, especially for low to medium pollutant concentrations in large volume flows. If necessary, concentrated solvents, for example, can be recovered and reused with the help of other technologies. Especially for exhaust air streams with low or medium concentrations of VOC and other harmful exhaust gases, the use of socalled VOC concentrators is of great advantage.

Limit values (so called MAK-value) for pollutants in ambient air have been defined by law, which should not be exceeded. This is done with the help of specially coated activated carbon that is amongst others in the activated carbon filter, and removes pollutants from the air of the wearer. But from the first, the breathing air needs to contain at least 19% oxygen! Dependent on application area you can choose between filter types as follows: Type A: colour code: brown Organic vapour or gas with boiling point above 65°C Type AX: colour code: brown Organic vapour or gas with boiling point under 65°C Type B: colour code: grey Inorganic vapour or gas (no CO) Type E: colour code: yellow Sulphur dioxide and acid gases or vapour Type K: colour code: green Ammonia and ammonia derivates Type Hg: colour code: red Mercury vapour Type CO: colour code: black Carbon monoxide Type P: colour code: white Dust Breathing filters, depending on filter type, can remove certain pollutants from...
