Abstract

According to the worldwide interest on CO₂ control, new techniques to reduce CO₂ are under development. This study focuses on CO₂ absorption and regeneration technology such as CO₂ capture and storage (CCS). CO₂ absorption is a kind of physical treatment. The absorption rate of a physical absorption method is generally weaker than that of a chemical method at room temperature. However it needs much less energy during the regeneration process. In the present study, SiO ₂/H₂O nanofluids are used to improve the CO₂ regeneration performance. The key parameters are the concentration of SiO ₂ nanoparticles and the system pressure during the regeneration process, which range from 0.005 to 0.05 vol% and 5-16 bar, respectively. It is found that the regeneration performance increased up to 12% at 0.01 vol% in comparison with the distilledwater.
