ABSTRACT:
An improved process for combustion flue gas conditioning in which ammonia is injected into a stream of said combustion flue gas, wherein urea is dissolved in water, forming a dissolved urea solution. The dissolved urea solution is heated and pressurized and the dissolved urea therein hydrolyzed, forming ammonia and carbon dioxide. The ammonia and carbon dioxide are then stripped from the resulting hydrolysis solution and injected into the stream of combustion flue gas to be treated. Water from the stripped hydrolysis solution is then recycled for use in dissolving fresh urea.
