CARBON DIOXIDE CAPTURE SYSTEM AND METHOD OF CAPTURING CARBON DIOXIDE

A system for recovering carbon dioxide comprises: 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 release carbon dioxide gas and regenerated liquid sorbent; and a dry transport mechanism configured to transport the solid material from the reaction chamber at the first pressure to the regeneration unit at a second higher pressure. A method of recovering carbon dioxide from a gas stream, comprises: chemically reacting carbon dioxide with a liquid sorbent to form a solid material; without adding a carrier fluid, dry pressurizing and transporting the solid material, to a regeneration unit; and heating the solid material in the regeneration unit to decompose the solid material to carbon dioxide gas and regenerated liquid sorbent.
