Highly efficient absorbents for CO2 capture from the flue gas of power station were developed. The development of absorbent for CO2 separation is the one of the core technologies in the manner of chemical absorption. In this study, novel absorbents for post-combustion CO2 capture gave the fast absorption rate, higher absorption capacity and fast stripping rate than those of MEA which is the representative chemical absorbent for CO2 separation. In addition, the newly developed absorbents have been evaluated their capability for CO2 separation by absorption screening test, VLE and their applications to pilot plant test. At pilot plant test, it was possible to reduce the operation energy of facility because KoSol-1 & 2 needed 1∼2 ∘C lower temperature of stripper, which have possess more than 50% of total energy required in CO2 separation process, than that of MEA when the newly developed absorbents, KoSol-1 & 2, were used as an absorbent, respectively. In the case of KoSol-2, the removal efficiency of CO2 was higher than that of MEA even in the 2 ∘C lower stripper temperature.
