ABSTRACT:
Stack gases containing pollutant gases and particulate matter are passed through a defined flow path into which at least one selected liquid reagent is introduced in a prescribed manner to intimately contact the stack gases therein. The liquid reagent scrubs the stack gases and thereby removes a substantial portion of the pollutant gases and particulate matter therefrom. One reagent may be used or several different reagents may be employed at different stages of the flow path to best effect removal of various different pollutants contained within the stack gases. Removal of sulfur dioxide is accomplished by a highly reactive and substantially non-abrasive reagent, such as a lime solution and such solution further effects removal of materials in trace amounts in the stack gases such as mercury, bergillium and vanadium. Removal of nitric oxide and other materials in trace amounts is also accomplished by the process which includes as a reagent an oxidant.
