"Carbon Dioxide Capture System And Methods Of Capturing Carbon Dioxide"

Abstract: In one embodiment, a system (10) for recovering carbon dioxide from a gas stream (24), comprising: a reaction chamber (14) having a first pressure and comprising a gas stream inlet; a phase-changing liquid sorbent (12), wherein the liquid sorbent (12) is chemically reactive with carbon dioxide to form a solid material; a regeneration unit (36) to decompose the solid material to released carbon dioxide gas and regenerated liquid sorbent (42); and a transport mechanism (100) disposed between the reaction chamber (14) and the regeneration unit (36) and configured to mix the solid material with a liquid to form a slurry, pressurize the slurry, and transport the slurry to the regeneration unit (36). In one embodiment, a method of recovering carbon dioxide from a gas stream (24), comprising: chemically reacting carbon dioxide with a phase-changing liquid sorbent (12) to form a solid material; mixing the solid material with a liquid to form a slurry; pressurizing and transporting the slurry to a regeneration unit (36); and heating the slurry to form carbon dioxide gas and regenerated liquid sorbent (42).
