Methods and systems for CO2 separation
First Claim
1. A system for separating carbon dioxide (CO2) from a gas stream, comprising:
- (i) a reaction chamber configured to receive a first liquid sorbent stream and the gas stream, wherein the reaction chamber is configured to react at least a portion of CO2 in the gas stream with the first liquid sorbent stream to form an entrained gas stream comprising a plurality of solid adduct particles;
(iii) a separation unit in fluid communication with the reaction chamber, wherein the separation unit is configured to receive the entrained gas stream and a second liquid-sorbent stream, and wherein the separation unit is configured to separate at least a portion of the plurality of solid adduct particles from the entrained gas stream to form an adduct stream and CO2-lean gas stream; and
(iii) a desorption unit in fluid communication with the separation unit, wherein the desorption unit is configured to receive the adduct stream, and wherein the desorption unit is configured to decompose the plurality of solid adduct particles to form a CO2 stream and a regenerated liquid-sorbent stream.

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.
