암모니아와 염화나트륨 수용액을 이용한 저농도 CO₂ 제거 연구

다국어 초록 (Multilingual Abstract)

Atmospheric concentration of greenhouse gases must be lowered, to reduce the risks of climate change. In this paper, absorption and reaction characteristics of low CO₂, NH₃ and NaCl reagents were investigated. As NH₃ concentrations increase CO₂ removal efficiency increase while absorption capacity decrease. Sparger type absorber shows 3 times higher absorption capacity than bubble type absorber. As temperature increase from 20 ℃ to 40 ℃, absorption capacity decrease from 0.026 to 0.009 g-CO₂/g-NH₃. Finally, it was found that combined solvents of NH₃ and NaCl are more efficient than NH₃ solvent alone, in capturing low concentration CO₂.
