Abstract: Systems and methods for separating carbon dioxide (CO2) from a gas stream are provided. The system includes a reaction chamber 20, a pressurization unit 30, and a desorption unit 40. The reaction chamber 20 is configured to receive a liquid sorbent stream 14 and the gas stream 12, to react at least a portion of CO2 in the gas stream 12 with the liquid sorbent and form an adduct stream 22. The pressurization unit 30 is configured to contact the adduct stream 22 with a pressurized CO2 stream 24 and form a pressurized adduct stream 32 that includes a liquid CO2 adduct. The desorption unit 40 is in fluid communication with the pressurization unit 30, and is configured to decompose at least a portion of the liquid CO2 adduct to form a CO2 stream 42 and a regenerated liquid sorbent stream 44.

Abstract: A method for treatment of a flue gas involves feeding the flue gas and a lean solvent to an absorber. The method further involves reacting the flue gas with the lean solvent within the absorber to generate a clean flue gas and a rich solvent. The method also involves feeding the clean flue gas from the absorber and water from a source, to a wash tower to separate a stripped portion of the lean solvent from the clean flue gas to generate a washed clean flue gas and a mixture of the water and the stripped portion of the lean solvent. The method further involves treating at least a portion of the mixture of the water and the stripped portion of the lean solvent via a separation system to separate the water from the stripped portion of the lean solvent.
