Electron beam dry scrubbing EBDS

In electron beam dry scrubbing (EBDS), flue gases from the combustion of medium- to high-sulfur fuels are injected with water and ammonia vapor, and expo.sed lo high-energy electron beams (Ratafia-Brown el al 1995). The SOt and NOj react to form ammonium sulfate and nitrate, and the aerosol product is collected for sale as a fertilizer. Several existing installations are operated on a large pilot scale, about 1% of plant-scale gas flow rates.
