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

► Non-condensable impurities can reduce CO2 storage capacity substantially. ► The degree of the reduction is greater than the molar fractions of the impurities. ► A maximum reduction of the capacity exists at a certain pressure. ► The maximum reduction of the capacity decreases with temperature. ► A generally applicable method is developed for evaluation of the effect.
