Abstract

The integrated gasification combined cycle (IGCC) is getting much more attention due to the rich reserves of coal around the world. In general, the absorption rate of a physical method such as the IGCC system is weaker than that of a chemical method, but it needs much less energy during the regeneration process. In this study, the main objective is to estimate the performance enhancement for CO₂ gas absorption and regeneration by using SiO₂/DI water and Al₂O₃/DI water nanofluids. The key parameters are the concentrations of SiO₂ and Al₂O₃ nanoparticles and the system pressure during the regeneration process. It is found that the maximum CO₂ absorption and regeneration performance enhancements are 23.5% and 11.8% at 0.01vol% of SiO₂ nanoparticles, respectively. However, in the case of Al₂O₃ nanoparticles, the CO₂ absorption performance increases 23.5% at 0.01vol%, but the regeneration performance decreases 11.2% at 0.01vol%, respectively. The enhancement mechanisms for CO₂ absorption and regeneration by nanoparticles are summarized and proposed in this study.
