Separation and/or sequestration apparatus and methods

摘要

Apparatus for separating CO2 from an electrolyte solution are provided. Example apparatus can include: a vessel defining an interior volume and configured to house an electrolyte solution; an input conduit in fluid communication with the interior volume; an output conduit in fluid communication with the interior volume; an exhaust conduit in fluid communication with the interior volume; and an anode located within the interior volume. Other example apparatus can include: an elongated vessel having two regions; an input conduit extending outwardly from the one region; an output conduit extending outwardly from the other region; an exhaust conduit in fluid communication with the one region; and an anode located within the one region. Methods for separating CO2 from an electrolyte solution are provided. Example methods can include: providing a CO2 rich electrolyte solution to a vessel containing an anode; and distributing hydrogen from the anode to acidify the electrolyte solution.

1. An apparatus for separating CO2 from an electrolyte solution, the apparatus comprising:
a vessel defining an interior volume and configured to house an electrolyte solution; an input conduit in fluid communication with the interior volume and configured to convey the electrolyte solution to the interior volume; an output conduit in fluid communication with the interior volume and configured to convey the electrolyte solution outside the interior volume; an exhaust conduit in fluid communication with the interior volume; an anode located within the interior volume and configured to provide hydrogen ions to the electrolyte solution within the vessel; and a cathode located within the interior volume; and further comprising a fluid conduit coupling the anode and the cathode, the cathode configured to provide H2 to the fluid conduit, wherein the anode comprises a porous electrode configured to receive H2 from the fluid conduit, and wherein the interior volume of the vessel is continuous between the cathode and the anode.
