It is important that reduce CO2 emission from flue gases due to mitigating the global warming problem. Absorbents for CO2 removal have recycled because of massive quanties and the price of absorbent. Most regeneration processes using chemical solvent have consumed 50~80% of entire energy. This is the main reason for developing high efficient absorbents for regeneration process.In this study, five alkanol amine aqueous solutions[MDEA, AMP, KIER-C3, MDEA/KIER-C3(KMC3-1), AMP/KIER-C3 (KAC3-1)] were used for CO2 absorption from flue gases to investigate regeneration heat by TGA-DSC analysis. The regeneration heat of KIER-C3(544 kcal/kg-CO2) was superior to that of MEA(964 kcal/kg-CO2). Also regeneration heat of CO2 loaded aqueous blends MDEA/KIER-C3(KMC3-1), AMP/KIER-C3 (KAC3-1) was 570~677 kcal/kg-CO2 and these values are still superior than that of MEA. |
