Abstract
A method for capturing carbon from a source of volatile pollutants includes the steps of capturing a mixture of volatile pollutants and air from the source of volatile pollutants, transporting the volatile pollutant-air mixture to an oxidizer module, converting the volatile pollutants into carbon dioxide within the oxidizer module, transporting the carbon dioxide from the oxidizer module to a contactor, loading the carbon dioxide onto sorbents within the contactor, and separating the carbon dioxide from the loaded sorbents to produce a concentrated carbon dioxide product stream. The step of separating the carbon dioxide from the loaded sorbents may optionally include the steps of passing the loaded sorbents to the oxidizer module, and then heating the loaded sorbents in the oxidizer module with the combustion of the mixture of volatile pollutants and air within the oxidizer module to produce the concentrated carbon dioxide product stream while regenerating the sorbents.
