ABSTRACT:
An apparatus and method for removing particulate and gaseous pollutants from flue gas. The flue gas enters a presaturation section and is treated with a coarse spray of solution recovered from the system. The saturated gas enters a primary contacting section and is contacted by an ultrafine mist of fresh solution containing a gaseous pollutant absorption agent. The fine mist has an average droplet size of approximately 20 microns. The gas moves to a secondary contacting section where it is contacted by a coarse spray of recirculated solution. If necessary, the gas is demisted. Finally, the gas is discharged into the environment. Usable spent solution is regenerated and reused. Unusable water byproducts containing contaminants are discharged.
