PROCESS FOR CAPTURING CO2 FROM A CO2-CONTAINING GAS STREAM INVOLVING PHASE SEPARATION OF AQUEOUS ABSORBENT

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...

Zusammenfassung: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.
