Abstract: A process capturing CO2 from a CO2-containing gas stream, contacting a CO2-containing gas stream with a CO2-absorbing agent in an absorption step in a vessel with maximum temperature T1 resulting in absorption of CO2. The CO2 absorbing agent comprising a polymer dissolved in an aqueous medium, the polymer, a thermoresponsive copolymer, comprising amine monomer distributed through the copolymer, subjecting the CO2-containing absorbing agent to a desorption step in a vessel with maximum temperature T2, releasing CO2, wherein T1 is below LCST of the thermoresponsive polymer at maximum CO2 loading, and T2 is above LCST of the thermoresponsive polymer at minimum CO2 loading. CO2 absorbing agent comprises amine component dissolved in the aqueous medium. Use of the specific polymer dissolved in an aqueous medium at T1, wherein amine monomer, distributed through the copolymer with an amine component, improves net CO2 sorption and high absorption speed, allowing a relatively small absorption reactor.

Abstract: The present invention relates to a process for capturing CO2 from a CO2—containing gas stream, comprising the steps of: (a) contacting a CO2-containing gas stream with a CO2-absorbing agent in an absorption step wherein the temperature of the CO2 absorbing agent at the end of the absorption step is below the LCST of the CO2-absorbing agent at the end of the absorption step, resulting in absorption of CO2; (b) increasing the temperature of the CO2-absorbing agent, wherein the temperature at the end of the desorption step is above the LCST of the CO2-absorbing agent at the end of the desorption step, resulting in the desorption of CO2; wherein the CO2-absorbing agent is a thermoresponsive CO2-absorbing agent comprising an amine-containing component, a solute inorganic salt, and water.
