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 NOscrubber column supplied with the compressed flue gas from the compressor, a liquid supply line for supplying liquid condensed at the condenser to the NOscrubber column, and a liquid recirculation line for recirculating liquid from the NOscrubber column to the condenser.

Treatment system and method for a flue gas from a combustion process

A system for reducing NOin 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 NOin 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.
