VOC advanced pretreatment before adsorption treatment in an odor treatment line - Azurair® Cool
The Azurair® Cool process is an optimized water scrubber dedicated to VOC’s removal. It uses the capacity of cold water to maximize the solubility of VOCs in a water scrubber and to dehumidify air flow before its entering an activated carbon filter.
The Azurair® Cool includes:
- A gas scribber, consisting of a packed column operating in counter current mode without liquid recirculation.
- A cooling unit to cool the washing water.



key figures
- 60% less waste*
- 10% reduction in energy consumption on the air treatment line
- 55% less CO2 eq emission*
*Compared to a conventional VOC treatment (adsorption on an activated carbon filter

- Reduced environmental footprint compared to conventional VOC treatment
- Odor removal twice as effective as conventional VOC treatment
- High performance: as an example, the VOC removal is improved by more than 30% when the washing water temperature is reduced by 7°C
- OPEX savings: reduction of activated carbon replacement frequency.
