영문 초록

Recently the more stringent emission standards of government promulgate the incentive for developing the technology capable of simultaneous removal of S02 and NOx from flue gas. This study was to develope an enhanced absorbent in reactivity and adsorption ability for removing SO₂ and NOx from flue gas. The characteristics of spray drying absorption(SDA) process and status of SDA process were studied, as well as analysis of properties of absorbent and its manufacturing method. CaO, MgO, and NaHC0₃ were selected as a alkali reagent, and they were mixed with fly ash(FA) or activated carbon powder(AC) and their the reactivity and adsorption ability toward SO₂ and NOx were greatly enhanced through hot water curing process. Among the selected alkali reagent, the removal ability of NaHC0₃ toward S0₂ and NOx was the highest. The surface area of MgO mixed with FA(30%) was greater than NaHC0₃, but the SO₂ and NOx removal performance of MgO mixed with FA(30%) was much lower than that of NaHC0₃. The removal quantity of S0₂ and NOx per mole of NaHC0₃ mixed with FA(30%) was 2.7 mole, this meant that the effect of physical adsorption was greater than chemical reaction between absorbent and acid gases.
