  • Methods and systems for separating condensable vapors from gases
    Patent number: 9250012
    Abstract: Condensable vapors such as carbon dioxide are separated from light gases in a process stream. The systems and methods employ a particle bed cooled by an in-bed heat exchanger to desublimate the condensable vapors from the process stream. The condensable vapors are condensed on the bed particles while the light gases from the process stream, which are not condensed, form a separated light-gas stream. The separated light-gas stream can be used in a recuperative heat exchanger to cool the process stream.

  • Methods and systems for generating power from a turbine using pressurized nitrogen
    Patent number: 8963347
    Abstract: An air separation unit is integrated with a power generating plant to improve the efficiency of power generation. The methods and systems improve the efficiency of power generation by utilizing liquid nitrogen from the air separation unit as the working fluid in a turbine. The liquid nitrogen is pressurized while in the liquid state. After warming the pressurized nitrogen stream by cooling the air for the air separator unit, the compressed nitrogen is expanded in a turbine to perform work. After expansion, the nitrogen is vented to ambient air. The nitrogen in its pressurized state can be used for energy storage and/or for smoothing out power demand on a power grid.

  • Systems and methods for separating condensable vapors from gases by direct-contact heat exchange
    Patent number: 8764885
    Abstract: Condensable vapors such as carbon dioxide are separated from light gases in a process stream. The systems and methods employ a direct exchange heat exchanger to desublimate the condensable vapors from the process stream. The condensable vapors are condensed by directly contacting a heat exchange liquid in the direct contact heat exchanger while the uncondensed light gases from the process stream form a separated light-gas stream. The separated light-gas stream can be used in a recuperative heat exchanger to cool the process stream.
