Methods and systems for CO2 separation
Abstract
A method for separating carbon dioxide (CO2) from a gas stream is provided. The method includes reacting at least a portion of CO2 in the gas stream with a plurality of liquid sorbent particles to form a plurality of solid adduct particles and a first CO2-lean gas stream; the solid adduct particles entrained in the first CO2-lean gas stream to form an entrained gas stream. The method includes separating at least a portion of the plurality of solid adduct particles from the entrained gas stream in a separation unit to form an adduct stream and a second CO2-lean gas stream. The method further includes heating at least a portion of the adduct stream in a desorption unit to form a CO2 stream and a regenerated liquid sorbent stream. A system for separating CO2 from a gas stream is also provided.
