Post-combustion carbon capture by co2 desublimation

Abstract

An apparatus for capturing a gas component from a gas mixture includes a co-current direct contact cooling chamber configured to form solid particles of the gas component by direct contact of a cryogenic liquid with the gas mixture, the co-current direct contact cooling chamber being configured to receive the gas mixture from a source of the gas mixture and to receive the cryogenic liquid from a supply of the cryogenic liquid. The apparatus also includes a separator coupled to an output of the co-current direct contact cooling chamber and configured to separate the solid particles of the gas component from a fluid mixture exiting the direct contact cooling chamber with the solid particles of the gas component to capture the gas component from the gas mixture.
