In the conventional CO2 capture and utilization process, pure CO2 gas collected from exhaust gases (e.g., CO2, N2 and O2) from facilities such as thermal power plants is mixed with H2 outside of the desorber and supplied to the CO2 reduction reactor. The conventional amine solution can absorb CO2 from the exhaust gas at about 40 deg.C, and pure CO2 is regenerated at 100 deg.C or higher. Novel H2 stripping regeneration technology has enabled the collection of CO2 at a low temperature (85 deg.C) by supplying H2 directly into the desorber.
