Abstract
A process is presented for reducing the concentration of pollutants in an effluent from the combustion of a carbonaceous fuel. The process comprises injecting a first treatment agent into the effluent at a first temperature zone and injecting a second treatment agent into the effluent at a second temperature zone, wherein the first and second treatment agents are injected under conditions effective to reduce the effluent pollution index.
