Abstract
Systems and methods are provided for using a multi-stage capture process for capture of COfrom air. A first or initial sorption process is used to sorb COfrom air. After sorption from the air is complete, the desorption step of the initial stage is used to form a secondary CO-containing stream that is passed into one or more additional sorption stages. This secondary CO-containing stream can be at a concentration of roughly 1.0 vol % or more. Sorption of COfrom the secondary CO-containing stream is performed using a different contacting method, such as a contacting method that is higher efficiency. The second or later COsorption stage can produce a CO-containing output stream with a COconcentration of 80 vol % or more, or 90 vol % or more, or 95 vol % or more. This high purity output stream can then be sequestered and/or used for further processing.
