Air Pollution Control
The Division of Air Pollution Control is focused on providing equipment and systems on turn-key basis for dedusting and for flue gas desulphurization.
ENFIL acts at all stages of the gas treatment process: from the capture of the pollutant or dust till its filtering and/or scrubbing and release to the atmosphere.
Dedusting
- Exhaust hoods: Fixed and movable hoods
- Filtration:
- Gas Scrubbers - Venturi type
- Handling of solids: drag chains, pneumatic conveying, etc.
Abatement of
acid gases
- DESULPHURIZATION: REMOVAL OF SOX WET, DRY AND SEMI-DRY
- DeNOx: catalytic and non-catalytic removal of NOx
