Separation and/or sequestration apparatus and methods
First Claim
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 comprisinga 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.

Abstract
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.
