Abstract
Plants and method of treating a combustion gas are presented in which NOx compounds are removed from the combustion gas to a predetermined level to thereby create a pre-cleaned combustion gas from which COis removed in an absorber using an amine solvent. Preferably, the predetermined level of NOx compounds reduces nitro-amines, especially nitrosamine emission from the absorber to quantities of equal or less than 100 ppb.
