Spray Dryer Absorbers

Environmental Elements is a leading supplier of Spray Dryer Absorber (SDA) Systems. Our state-of-the art, direct drive, variable speed rotary atomizers manufactured by Komline-Sanderson, coupled with a pebble lime storage preparation system incorporate spray dryer absorbers built to EEC's specifications, and an electrostatic precipitator or fabric filter systems for particulate collection. The total system represents the state-of-the art in spray dryer acid gas scrubbing systems for municipal and hazardous waste incinerators.

Although the majority of heavy metals generated by waste incineration condense on fly ash or spray-drying products and are removed from the gas stream in the particulate collector, mercury may remain as a vapor throughout conventional spray-drying processes. To control mercury emissions, Environmental Elements provides a mercury removal system which adds metered activated carbon, in slurry form, through the atomizer. Our method of removal simplifies the handling of the activated carbon dust and allows the atomized spray of carbon to mix effectively with the flue gas. Mercury is then adsorbed into the activated carbon and is removed downstream in the particulate collector.
