New and useful system and method concepts are provided, for removing carbon dioxide from a flow of carbon dioxide laden air. More specifically, a sorbent structure is used in new and useful structures and techniques to bind carbon dioxide in a carbon dioxide laden air stream, and process heat is used to separate carbon dioxide from the sorbent structure and regenerate the sorbent structure.
대표청구항▼
1. A method of removing carbon dioxide from carbon dioxide-laden ambient air, the method comprising: directing a flow of the carbon dioxide-laden ambient air through a unitary, porous, pancake-shaped carbon dioxide capture structure that is supporting an amine sorbent capable of binding carbon dioxi
1. A method of removing carbon dioxide from carbon dioxide-laden ambient air, the method comprising: directing a flow of the carbon dioxide-laden ambient air through a unitary, porous, pancake-shaped carbon dioxide capture structure that is supporting an amine sorbent capable of binding carbon dioxide to the sorbent, so as to remove carbon dioxide from the ambient air,moving said unitary, porous, pancake shaped carbon dioxide capture structure from contact with said flow into a regeneration enclosure,regenerating the sorbent by causing saturated steam carrying process heat at a temperature of not greater than about 120° C. to come into contact with the unitary, porous, pancake shaped, carbon dioxide capture structure in the regeneration enclosure, thereby causing separation of carbon dioxide from the sorbent,withdrawing separated carbon dioxide from the regeneration enclosure,selectively moving the unitary, porous, pancake shaped, carbon dioxide capture structure out of the regeneration enclosure back to a position disposed in the flow path of carbon dioxide-laden ambient air, thereby permitting the regenerated sorbent to bind additional carbon dioxide from the flow of said carbon dioxide-laden ambient air, andcyclically repeating said movements of the unitary, porous, pancake shaped carbon dioxide capture structure between the regeneration enclosure and into the flow of carbon dioxide-laden ambient air. 2. The method of claim 1 wherein the amine sorbent is coated on the surface area of the unitary, porous, pancake-shaped carbon dioxide capture structure. 3. The method of claim 1 wherein the unitary, porous, pancake shaped, carbon dioxide capture structure has a thin cross-section in the direction of the flow of ambient air and a large surface area perpendicular to the flow of ambient air.
