Spray Dryer - an overview | ScienceDirect Topics

3.2.2.1 Spray dryer absorber and CFB absorber systems. Spray dryer-based FGD historically has been the most common “dry” FGD technology used in the United States dating back to the early 1980s. However, it is somewhat of a misnomer to call this technology “dry,” as a slaked-lime-based aqueous slurry is actually fed to the spray dryer absorber (SDA). The slurry is finely atomized in the ...

Spray dryer absorber for SO2, HCl, HF removal

The Spray Drying Absorption technology features excellent performance for absorption, not only of primary pollutants such as SO 2 and HCl.. Due to finely atomized absorbent sprayed into the flue-gas stream and the subsequent dust removal, pollutants such as SO 3, HF, etc. will be completely removed.. This facilitates the use of carbon steel as construction material throughout the flue-gas path.
