Systems, methods, and apparatus for capturing CO
Systems, methods, and apparatus for capturing CO 2 using a solvent are provided. A gas that includes carbon dioxide may be mixed with a solvent that is operable to absorb at least a portion of the carbon dioxide from the gas. The solvent containing the carbon dioxide may be provided to at least one removal system operable to remove at least a portion of the liquid contained in the solvent. The solvent output by the removal system may be stripped to extract at least a portion of the carbon dioxide from the solvent.
1. A method for capturing carbon dioxide, the method comprising:
mixing a gas comprising carbon dioxide with a solvent operable to absorb at least a portion of the carbon dioxide from the gas;
providing the solvent comprising carbon dioxide to at least one removal system operable to remove at least a portion of the liquid contained in the solvent, wherein the at least one removal system partially boils the solvent; and
stripping the solvent output by the removal system to extract at least a portion of the carbon dioxide from the solvent.
2. The method of claim 1 , further comprising:
compressing the carbon dioxide extracted from the solvent.
3. The method of claim 1 , wherein the gas comprises gas emitted from burning a fossil fuel.
4. The method of claim 1 , wherein the solvent comprises monoethanol amine.
5. The method of claim 1 , wherein the at least one removal system comprises a reverse osmosis liquid removal system.
6. The method of claim 1 , wherein the at least one removal system comprises one or more membranes operable to remove at least a portion of the liquid contained in the solvent.
7. A system for capturing carbon dioxide, the system comprising:
an absorber operable to receive a gas comprising carbon dioxide and to mix the gas with a solvent, wherein the solvent absorbs at least a portion of the carbon dioxide;
at least one removal system operable to receive the solvent comprising absorbed carbon dioxide from the absorber and further operable to remove at least a portion of the liquid contained in the solvent, wherein the at least one removal system partially boils the solvent; and
a stripper operable to heat the solvent output by the removal system to extract at least a portion of the carbon dioxide from the solvent.
8. The system of claim 7 , further comprising:
a compressor operable to compress the carbon dioxide extracted from the solvent.
9. The system of claim 7 , wherein the gas comprises gas emitted from burning a fossil fuel.
10. The system of claim 7 , wherein the solvent comprises monoethanol amine.
11. The system of claim 7 , wherein the at least one removal system comprises a reverse osmosis liquid removal system.
12. The system of claim 7 , wherein the at least one removal system comprises one or more membranes operable to remove at least a portion of the liquid contained in the solvent.
13. A method for capturing carbon dioxide, the method comprising:
mixing a gas comprising carbon dioxide with a solvent, wherein the solvent absorbs at least a portion of the carbon dioxide from the gas;
removing at least a portion of the liquid from the solvent comprising carbon dioxide, wherein the removal comprises partially boiling the solvent; and
stripping the solvent after at least a portion of the liquid is removed in order to extract at least a portion of the carbon dioxide from the solvent.
14. The method of claim 13 , further comprising:
compressing the carbon dioxide extracted from the solvent.
15. The method of claim 13 , wherein the solvent comprises monoethanol amine.
16. The method of claim 13 , wherein removing at least a portion of the liquid from the solvent comprises removing liquid from the solvent utilizing a reverse osmosis system.
17. The method of claim 13 , wherein removing at least a portion of the liquid from the solvent comprises removing liquid from the solvent utilizing one or more membranes.
