Application 07
Gas and Odour Control
Odours and organic vapours in air or process gases cause nuisance, exposure and process issues.
Quick answer
Can activated carbon remove odours?
Yes. Many odour-causing compounds and organic vapours are adsorbed by activated carbon. Air or gas is passed through a packed bed of granular carbon, which holds these compounds on its surface.
How it works
Many odour-causing compounds and organic vapours are adsorbed by activated carbon. Air or gas is passed through a packed bed of granular carbon, which holds them on its surface.
Granule size, bed depth and airflow determine contact time and pressure drop.
- 01

Gas and Odour Control: common questions
Does humidity affect activated carbon beds?
High humidity can reduce the capacity of activated carbon for some vapours, because water vapour competes for the pore surface.
How long does a carbon bed last?
It depends on the concentration of the compounds, the airflow and the bed size. Beds are replaced when monitoring or outlet odour shows breakthrough.
