Systems and methods for removing components of a gas mixture
A system for removing components of a gaseous mixture is provided comprising: a reactor fluid containing vessel having conduits extending therefrom, aqueous fluid within the reactor, the fluid containing a ligand and a metal, and at least one reactive surface within the vessel coupled to a power source. A method for removing a component from a gaseous mixture is provided comprising exposing the gaseous mixture to a fluid containing a ligand and a reactive metal, the exposing chemically binding the component of the gaseous mixture to the ligand. A method of capturing a component of a gaseous mixture is provided comprising: exposing the gaseous mixture to a fluid containing a ligand and a reactive metal, the exposing chemically binding the component of the gaseous mixture to the ligand, altering the oxidation state of the metal, the altering unbinding the component from the ligand, and capturing the component.
1. A method of capturing a component of a gaseous mixture, the method comprising:
exposing the gaseous mixture to an aqueous fluid containing a ligand and a reactive metal, the exposing chemically binding the component of the gaseous mixture to the ligand, wherein the fluid exists about an electrode;
using the electrode to alter the oxidation state of the metal to unbind the component from the ligand;
and capturing the component, wherein the component is carbon dioxide.
2. The method of claim 1 wherein the ligand is NH 3 and the metal is Cu.
3. The method of claim 2 wherein the carbon dioxide is chemically bound to NH 4 OH.
4. The method of claim 3 wherein the altering the oxidation state of the metal releases the carbon dioxide from the NH 4 OH.
5. The method of claim 1 further comprising returning the oxidation state of the metal to the state before it was altered.
6. The method of claim 5 further comprising again exposing the gaseous mixture to the aqueous fluid.
