Spray dryer absorber for flue gas desulphurization
Fossil-fueled power plants, waste incinerators, and industrial installations often face the challenge of removing acidic pollutants, heavy metals, and dust from flue gases. Efficiently addressing these emissions is crucial to meet environmental regulations and minimize environmental impact.
Removes acidic pollutants and heavy metals efficiently
The GEA Spray Dryer Absorber (SDA) is a semi-dry flue gas desulphurization process, utilizing slaked lime (Ca(OH)2) to transform gaseous pollutants like SO2, SO3, HCl, and dioxins into a stable, dry powder for easy storage and transport. This process operates by introducing hot flue gas into the absorber where it contacts a highly reactive absorbent atomized by a Rotary Atomizer, facilitating efficient neutralization and quick evaporation. Key features such as peak-control and activated-carbon injection ensure low mercury and dioxin emissions. The SDA process is tailored to meet client-specific environmental regulations and is widely applied in power plants, steel plants, and waste incinerator facilities. Over 200 installations globally highlight its reliability and efficiency, with absorbers capable of treating up to 2,000,000 Nm3/h in a single unit.
