Uses EDV® Technology to Scrub Particulates, SO2 and SO3 in

Flue/Process Gas Streams.

Utilizes an Aqueous Solution of Sodium Phosphate as Scrubbing

Buffer for the Absorption of SO2.

Minimizes Operating Costs by Regenerating the Scrubbing Buffer

Using Low Pressure Steam.

Produces a By-Product (a greater than 90% concentrated SO2 stream

that can be used as feed to a SRU, Sulfuric Acid Plant, SO2

Compressor or for other applications.)

Virtually Eliminates Liquid Effluent Discharge from Scrubber.
