ABSTRACT:
A system and method of converting flue gas pollutants to marketable byproducts of ammonium bisulfite and ammonium bisulfate, which are collected, and to other harmless byproducts which may be safely discharged is provided. The system removes as much particulate material and reaction inhibiting coal tar components as possible via an electrostatic precipitator and then passes the flue gas through a heat exchanger, wherein it is cooled by boiler feedwater. A suds producing detergent is introduced to the flue gas in order to separate any remaining coal tar components from the condensing moisture. Due to the removal of the tar components, sulfur dioxide and nitrous oxide readily dissolve in the condensing moisture when sufficiently cooled.
