Method And System For Pretreatment Of Gaseous Effluent For Capturing Post-Combustion Co2
Patent No. EP3944890 (titled "Method And System For Pretreatment Of Gaseous Effluent For Capturing Post-Combustion Co2") was filed by IFP Energies Nouvelles on Jul 15, 2021. The application was issued on Sep 6, 2023.
Patent Summary
This process separates acidic gases (e.g., $\text{CO}_2$) from a gaseous effluent using an aqueous amine absorbent. The effluent is first burned with fuel in a combustion device to produce a hot, acidic gaseous effluent, which simultaneously reduces oxygen levels to prevent amine degradation. This hot effluent is cooled in an exchanger, producing a cold acidic effluent for contact with a lean absorbent solution in a separation unit. This contact yields a lean gaseous effluent and a rich absorbent solution. The rich solution is regenerated in a column to recover the acidic gas and restore the lean absorbent. Energy for this regeneration is provided by a high-pressure liquid fluid introduced into the exchanger, which is converted into high-pressure vapor.
