2-16　Development of Phase Separation Solvent and H₂ Stripping Process to Save Energy of CO₂ Capture

Abstract

To develop the energy-saving CO₂ capture from exhaust gas, we have been studying on both absorbent and process. As an absorbent, we have developed a phase separation solvent that separates into two liquid phases during CO₂ absorption, and as a process, we have developed a H₂ stripping that supplies H₂ to the desorber. We will report the results of case studies with our developed solvents and processes.
