Publication number: 20240115993Abstract: Systems and methods for providing regeneration heat to a sorbent material and subsequently recovering a significant portion of the heat are provided. The systems and methods are useful, for example, for energy-efficient direct capture of carbon dioxide (CO2) from the atmosphere or flue gases. The systems and methods include introducing steam generated by an evaporator into a reactor of the system to directly heat sorbent material in the reactor and to purge desorbed CO2 from the reactor using the steam. Water condensing within the reactor is drained and returned to the evaporator. The purged steam and CO2 from the reactor are directed to a vapor re-compressor to lift their temperature and then to a condenser or re-boiler where the water is condensed and separated from the CO2 and latent heat transferred to the cooling water is recovered, optionally via use of a jet ejector.Type: ApplicationFiled: October 10, 2023Publication date: April 11, 2024Inventors: Brian HOLMAN, David WAIT, Mazdak KEBRIA
