ADSORPTION ON ACTIVATED CARBON
Activated carbon is an inert solid adsorbent material used to remove contaminants from process gas streams.
Removal of pollutants takes place through adsorption phenomena based on surface interactions between contaminants and carbon surface.
The regeneration phase of activated carbon foresees that the volatile organic compounds VOC can be desorbed from the activated carbon :
• the regeneration occurs externally from the system and activated carbon need to be replaced periodically, typically in case of a complex mixture of different compounds
• the activated carbon is regenerated internally to the plant through a specific cleaning system with injection of steam
