Flue Gas Dry Scrubbing Systems

The Swenson flue gas dry scrubbing system (FGD) is designed to remove sulfur dioxide, hydrogen chloride and other contaminants from flue gas.

The FGD system consists of an alkali (Na or Ca) feed preparation, spray dryer, and dry collector (fabric filter or electrostatic precipitator). Alkali feed is atomized by means of a two-fluid nozzle or centrifugal atomizer. Collection efficiencies of up to 99% on HCl and over 70% on SO2 can be achieved.
