Abstract: Provided are systems and methods for obtaining nitrogen and carbon dioxide gases from a flue gas. A method according to some embodiments comprises receiving a flue gas at an inlet of a selective catalytic reduction system, wherein the flue gas comprises one or more NOx gases; reducing the one or more NOx gases to N2 gas in the selective catalytic reduction system; receiving an output gas from the selective catalytic reduction system at an inlet of a gas separation membrane; and separating the output gas into a retentate and a permeate using the gas separation membrane, wherein the retentate comprises N2 gas.
