  • Patent number: 12398880
    Abstract: A method for isolating substantially pure carbon dioxide from flue gas is provided. The method can include combusting carbon based fuel to form flue gas; cooling the flue gas to provide substantially dry flue gas; removing N2 from the dry flue gas to provide substantially N2 free flue gas CO2; and liquifying the substantially N2 free flue gas CO2 to form substantially pure carbon dioxide.

  • Publication number: 20250044022
    Abstract: Systems for separating CO2 from a flue gas source are provided. The systems can include 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. Methods for separating CO2 from a flue gas source are provided. The methods can include liquefying the CO2 stream to form both CO2 liquid and CO2 vapor; and using at least a portion of the CO2 vapor to form the CO2 liquid during the liquefying.

  • Publication number: 20230256388
    Abstract: Combustion systems are provided that can include a combustion assembly operatively engaged with an air intake, wherein the air intake performs air enrichment. Methods for enriching air to a combustion assembly are also provided. The methods can include: forming an N2-rich stream and an O2-rich stream from a first air stream; supplementing a second air stream with the O2-rich stream to enrich the second air stream with O2; and combusting the enriched air stream. Systems for separating CO2 from flue gas are also provided. The systems can include a vortex tube assembly operably coupled to a component of the system that provides pressurized N2. Methods for heating or cooling components of a system for separating CO2 from flue gas are also provided.
