The effect of impurities in oxyfuel flue gas on CO2 storage capacity

Carbon capture and storage (CCS) is one of the major transformative technologies for reducing atmospheric CO2 emissions from large CO2 emitters where a large potential for geological CO2 storage exists. CO2 captured from the emitters contains various impurities, such as N2, O2, Ar, SOx, etc., and allowing these impurities to be stored together with CO2 would reduce the cost of CO2 capture. However, the impurities would have various undesirable...
