Air & VOC Control

Activated carbon in air purification adsorbs volatile organic compounds, solvent vapours, odour molecules, and low-concentration toxic gases. Granular beds are the standard for fixed systems; pellets offer lower pressure drop for continuous high-throughput applications.

How It Works

The process, step by step

Activated carbon in air purification adsorbs volatile organic compounds, solvent vapours, odour molecules, and low-concentration toxic gases. Granular beds are the standard for fixed systems; pellets offer lower pressure drop for continuous high-throughput applications.

01
Gas stream entry
Contaminated air enters the carbon bed. Flow rate and bed depth determine contact time and removal efficiency.
02
Adsorption in micropores
VOC molecules are captured in the micropore network of the carbon. Coconut shell carbon is preferred for its micropore density.
03
Bed saturation & replacement
Breakthrough is detected by downstream monitoring. Bed is either replaced (once-through) or regenerated with steam.
Key Specifications
CTC Activity
45u201380%
Carbon tetrachloride activity is the key indicator for gas-phase micropore capacity
Pressure Drop
Pellets < GAC
3mm pellets offer significantly lower pressure drop than equivalent 4u00d78 GAC u2014 important for energy cost
Hardness
>95% (GAC)
Bed carbon must survive packing and airflow without generating fine particles that bypass the system
