In situ apparatus and method for providing deuterium oxide or tritium oxide in an industrial apparatus or method
16 May 23
In an aspect, an electrochemical hydrogen isotope recycling apparatus for recycling a feedstream comprising a single isotope of hydrogen, comprising: an electrochemical recycling unit, the unit comprising an anode; a cathode; an isotope-treated, cation exchange membrane operatively disposed between the anode and cathode, the isotope-treated, cation exchange membrane having heavy water containing the isotope of hydrogen therein, the unit configured to receive the feedstream containing the single isotope of hydrogen; wherein the single isotope is deuterium or tritium and when the single isotope is deuterium, the heavy water comprises D2O and when the single isotope is tritium, the heavy water is T2O.

Utility
Electrochemical carbon dioxide recovery system
18 Oct 22
In an embodiment, a method for recovering carbon dioxide comprises introducing a carbon dioxide rich stream to a scrubber comprising a metal hydroxide and allowing the carbon dioxide to react with the metal hydroxide to form a metal carbonate; directing a metal carbonate stream from the scrubber to an electrochemical concentrator and applying a potential to the electrochemical concentrator to form a metal hydroxide stream and a separated carbon dioxide stream; directing the metal hydroxide stream comprising a recovered metal hydroxide and hydrogen to an electrochemical separator and applying a potential to the electrochemical separator to separate the hydrogen forming a hydrogen recycle stream from the recovered metal hydroxide forming a metal hydroxide recycle stream; and directing the separated carbon dioxide stream to a gas liquid separator and separating the separated carbon dioxide stream into a recycled water stream and a concentrated carbon dioxide stream.

Utility
Air-water extraction system
7 Jun 22
Disclosed herein is an air-water extraction system that includes a water selective membrane configured to transport water from humid air via selective diffusion through the water selective membrane; a low pressure chamber in fluid communication with the water selective membrane and a hydrogen gas inlet configured to deliver a dry hydrogen to the low pressure gas chamber, a membrane and electrode assembly comprising an anode, a proton exchange membrane, a cathode, and a power supply; wherein the anode is in fluid communication with the low pressure chamber, a high pressure chamber in fluid communication with the cathode for receiving a saturated hydrogen and a liquid water from the cathode; a water conduit in fluid communication with the high pressure chamber configured to remove the liquid water from the high pressure chamber, and a hydrogen conduit for removing the saturated hydrogen from the high pressure chamber.
