Three basic methods to separate gases

Cryogenic separation is widely used commercially for streams that already have high CO2 concentrations (typically 90%) but it is not used for more dilute CO2 streams. A major disadvantage of cryogenic separation of CO2 is the amount of energy required to provide the refrigeration necessary for the process, particularly for dilute gas streams.
