In one embodiment, a system for recovering carbon dioxide from a gas stream, comprising: a reaction chamber having a first pressure and comprising a gas stream inlet; a phase-changing liquid sorbent, wherein the liquid sorbent is chemically reactive with carbon dioxide to form a solid material; a regeneration unit to decompose the solid material to released carbon dioxide gas and regenerated liquid sorbent; and a transport mechanism disposed between the reaction chamber and the regeneration unit 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. In one embodiment, a method of recovering carbon dioxide from a gas stream, comprising: chemically reacting carbon dioxide with a phase-changing liquid sorbent 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; and heating the slurry to form carbon dioxide gas and regenerated liquid sorbent. |
