Overview

This analysis shows improved CO₂ capture and reduced energy consumption in phase-change absorbents for maritime, indicating potential for carbon emissions reduction.

Key Points

  • CO₂ absorption capacity improved by 46% compared to traditional methods, achieving 3.17 mol CO₂/kg solvent.
  • Utilizing a unique combination of DETA with phase separation agents including n-butanol led to effective phase separation upon CO₂ absorption.
  • The DETA + DMSO + H₂O absorbent's energy consumption was only 29% of the MEA-based absorbent, highlighting its efficiency.
  • These findings may enable further development of energy-efficient onboard carbon capture technologies.
