Claim 14:
15. A method for capturing carbon and methane from a methane source, the method comprising the steps of:
acquiring a low-concentration methane-air mixture from the methane source;
transporting the low-concentration methane-air mixture to a calciner;
combusting the low-concentration methane-air mixture within the calciner, wherein the combustion of the low-concentration methane-air mixture within the calciner produces a carbon dioxide exhaust gas stream;
transporting the carbon dioxide exhaust gas from the calciner to a contactor within the carbon dioxide capture module;
feeding an atmospheric mixture of air and carbon dioxide to the contactor;
transferring carbon from the carbon dioxide exhaust gas and the atmospheric mixture of air and carbon dioxide to carbon capture sorbents in the contactor;
transferring the carbon capture sorbents loaded with carbon dioxide from the contactor to the calciner; and
heating the carbon capture sorbents in the calciner to release carbon dioxide in a concentrated carbon dioxide product stream while regenerating the carbon capture sorbents.
