The nature of the pollutant is the characteristic that most influences the adsorption efficiency of the activated carbon. In fact, depending on their nature and their chemical characteristics, pollutants can be highly adsorbable (benzene, kerosene, fumes …), medium adsorbable (chlorine, acetone, ethylene …) or little adsorbable (propane, ammonia …). All ketones cause self-combustion problems so the carbons are not renewable.
The quantity and quality of adsorbent material effectively used depends on the concentration and type of the solvents (VOCs) to be treated.
The use of common activated carbon is recommended for temperatures up to a maximum of 50-60 C. To prevent a rapid saturation of the activated carbon, it is necessary to work with a relative humidity lower than 60%.
The typical efficiency of a Chemsorb® activated carbon filter can reach 95%, depending on the material’s degree of retention and design parameters.
The Chemsorb® activated carbon filter is designed by Tecnosida® on the basis of the data provided by you, in order to maximize the adsorption efficiency. It’s possible to adapt the activated carbon filter to your specific needs and to the peculiarities of your industrial process. Contact Tecnosida to receive specific advice!
Tecnosida offers both circular and rectangular models. The circular one is composed of robust carbon steel sheet elements, rolled and painted, and also has support legs. The rectangular type is made of press formed galvanized panels, assembled and bolted to each other. Alternatively, they can be made of other materials.
This type of construction makes future expansion of the purifier simple. Chemsorb® consists of compact elements that allow the spent carbon to be easily replaced with new refills.
It is therefore a very simple equipment to manage, both in operation and for maintenance.
