  • Publication number: 20250236169
    Abstract: A method and conditioning system for conditioning exhaust gas are provided. The conditioning system includes one or more heat removal systems for removing heat from an exhaust gas. The conditioning system also includes a condensate removal system fluidly coupled with, and positioned downstream of, the one or more heat removal systems. The condensate removal system is operable to remove moisture from the exhaust gas. In some variants, the conditioning system further includes one or more fluid chambers fluidly coupled with, and positioned downstream of, the condensate removal system. Each fluid chamber defines an interior in which a capture medium is contained. The cooled, moisture-depleted exhaust is selectively distributed to the fluid chambers to allow for harvesting or capture of a set of target species from the exhaust gas.
