Abstract: A system for reducing NOx in a flue gas stream, including an absorption element, a first inlet in fluid communication with the chamber configured to deliver a pressurized flue gas to the chamber, and a second inlet in fluid communication with the chamber configured to deliver an absorbing additive to the chamber. An outlet is in fluid communication with the chamber to exhaust from the chamber flue gas that has contacted the absorbing additive. A method for reducing NOx in a flue gas including the steps of: providing a flue gas in a chamber of an absorption element, providing an absorbing additive so that it contacts at least a portion of the flue gas, and exhausting at least a portion of the flue gas from the chamber.

Abstract: The treatment system for a flue gas from a combustion process includes a condenser, a compressor for compressing the flue gas deprived of moisture at the condenser, a NO2 scrubber column supplied with the compressed flue gas from the compressor, a liquid supply line for supplying liquid condensed at the condenser to the NO2 scrubber column, and a liquid recirculation line for recirculating liquid from the NO2 scrubber column to the condenser.
