EAD™
TECHNICAL DESCRIPTION
A pioneering solution designed to optimize reagent efficiency and achieve superior SO₂ removal.
The system is based on the injection of the fresh hydrated lime reagent in a Venturi Reactor
Turbulent flow ensures intimate contact between reagent and acids.
Three main proprietary components:
- A Venturi Reactor
- A Fabric Filter Dust Collector
- A Conditioning Drum
Pollutants removed
particulates, ash, SO₂, SO₃, HCl, HF, mercury, dioxins/furans, heavy metals, VOCs

The Conditionning Drum
The recycled reagent is humidified in a Conditioning Drum before entering Venturi reactor:
- Finely atomized water for humidification of reagent particles
- Moisture on material to cool flue gases in Venturi reactor
Main benefits:
- Ideal reaction temperature in Venturi reactor
- Optimum conditions for increased reactivity of reagent with SO₂ and other acid gases
ADVANTAGES
- Multi-pollutant control: SO₂ , SO₃, HCl, HF, Dioxins/ Furans
- PM10, PM2.5
- Dry by-product: zero liquid discharge
- Optimized reagent and electrical consumption
- Flexible and compact customized design
- Low on-line maintenance
- Agglomeration of solid particles
- Low Pressure drop
- Low hydrated lime consumption
