CO2 Separation Systems and Methods

A system for separating CO2 from a flue gas source, the system comprising:

• a flue gas source;
• the flue gas source comprising at least CO2 and N2;
• a separation component operatively coupled to the flue gas source and configured to separate CO2 from N2 and form separated CO2;
• a liquefaction component operatively coupled to the separation component and comprising a recuperative heat exchanger configured to receive the separated CO2 from the separation component and reduce the temperature of the separated CO2 by exchanging the heat of the separated CO2 with CO2 vapor generated by the liquefaction component and/or a storage component operatively coupled to the liquefaction component and configured to receive liquid CO2 from the liquefaction component;
• and
• the storage component comprising a CO2 storage vessel and/or CO2 transport vehicle;
• wherein one or both of the liquefaction component and/or the storage component are operatively coupled with the recuperative heat exchanger to provide at least a portion of the CO2 vapor generated during liquefaction and/or storage to the recuperative heat exchanger for cooling the separated CO2.
