1-13　Evaluation of CO₂ absorption and regeneration performance of low-energy phase-separation solvent

Abstract

Carbon dioxide capture and storage (CCS) is expected to play a role in combating global warming. Thus,

research and development are progressing around the world. However, there are limitations such as the

demonstration examples being limited to cases where the CO₂ capture site and storage site are close. In recent years, Carbon dioxide Capture and Utilization (CCU) using captured CO₂ has attracted attention.

This time, we will focus on technologies that reduce CO₂ and convert it into fuels and chemicals, mainly focusing on methanation. Energy saving can be achieved by integrating the CO₂ capture process and the CO₂ utilization process.

In this paper, we report the results of energy calculation in the CO₂ separation by the new process using the phase-separated type CO₂ absorbent developed so far, and the experimental results of continuous operation using this process.
