Abstract: A method including acidifying a solution including dissolved inorganic carbon; vacuum stripping a first amount of a carbon dioxide gas from the acidified solution; stripping a second amount of the carbon dioxide gas from the acidified solution; and collecting the first amount and the second amount of the carbon dioxide gas. A system including; a first desorption unit including a first input connected to a dissolved inorganic carbon solution source to and a second input coupled to a vacuum source; and a second desorption unit including a first input coupled to the solution output from the first desorption unit and a second input coupled to a sweep gas source.

Abstract: A system includes a first desorption unit comprising a first input coupled to a dissolved inorganic carbon (“DIC”) solution source and a second input coupled to a vacuum source, the first desorption unit is operable to remove carbon dioxide gas from an acidified solution from the DIC solution source and comprises a solution output. A second desorption unit in the system comprises a first input coupled to the solution output from the first desorption unit and a second input coupled to a sweep gas source, the second desorption unit is operable to remove carbon dioxide gas from the solution output from the first desorption unit.
