A technology, Rotorfilter, provides a total, or as required, emission control for high sulfur coal and solid fuels fired utility system and is commercially available and proven. The Rotorfilter technology can remove SOx, NOx and particulate matter simultaneously from the flue gas stream of coal fired electric power stations. Pilot and full-scale on line test results indicate up to 98% plus particulate, 96% plus SOx, and 65% more of NOx removal achieved. Rotorfilter technology is an innovative wet scrubbing device using very low quantity of water and limited quantity of chemicals to achieve high efficient pollutants retention. In addition, the technology also claims up to 10% energy recovery from the flue gas by attaching a corrosion resistant advanced heat exchange device to cool the flue gas prior to its cleaning while performing efficient emission control of the flue gas. The paper will update technological status of the Rotorfilter and the corrosion resistant condensing heat exchanger with detailed results and cost estimation for industrial applications.
