Abstract
Systems, methods, and apparatus for capturing CO2 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.
Claims17
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.
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.
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.
