Abstract

The present invention relates to a method and a system for cleaning a CO2 rich flue gas stream containing water vapor and NOX prior to CO2 sequestration. The method and system include heating the flue gas stream to a temperature suitable for selective catalytic reduction (SCR) of NOX in a flue gas heater, reducing at least some of the NOX in the heated flue gas stream to N2 by SCR, and removing at least some of the water vapor from the NOX depleted flue gas stream by adsorption in an adsorption drier.
