SOX/NOX/HG REMOVAL FROM FLUE GAS BY AMMONIA WET SCRUBBING USING IRON CHELATE CATALYSTS

摘要

A method of removing contaminants from a flue gas provides the flue gas to an absorber tank. A metal chelate catalyst is provided to an ammonia solution and in turn the ammonia and catalyst solution is provided to the absorber tank for mixing with the flue gas. The ammonia and catalyst solution is then oxidized after mixing with the flue gas and the metal chelate catalyst is separated from the spent solution after the solution has been oxidized.
