나트륨계 흡수용액의 이산화탄소 흡수특성을 알아보기 위하여 회분식 기-액 흡수평형 반응기를 이용하여 Na₂CO₃ 5%, 10%, 15%, 20% 수용액에 대한 이산화탄소 흡수능 및 초기흡수속도를 측정하였으며 반응온도는 40℃이였다. 또한, 알칼리염계 흡수제(KHCO₃, CaCO₃, K₂CO₃)들의 혼합에 따른 초기흡수속도를 비교하였다. 농도에 따른 실험결과 10%의 Na₂CO₃에서 가장 좋은 흡수능 및 흡수속도를 보였고, 알칼리염계 흡수제들 중에서 K₂CO₃와 혼합할 때 흡수속도가 다소 증가되었다. Na₂CO₃ 5% 용액의 초기흡수속도를 개선시키기 위하여 Pz와 Pp를 각각 첨가하여 실험한 결과, 증진제를 첨가함으로써 초기흡수속도를 증가시킬 수 있었다.

다국어 초록 (Multilingual Abstract)

The absorption capacity and initial absorption rate in 5 %, 10 %, 15 % and 20 % Na₂CO₃ under the constant temperature at 40℃ and the initial absorption rate in mixture of different alkaline salts such as KHCO₃, CaCO₃ and K₂CO₃ were measured using batch type stirred cell contractor. 10 % Na₂CO₃ showed the highest absorption capacity and Na₂CO₃ and K₂CO₃ showed the somewhat increased absorption capacity and initial absorption rate respectively. Further more, we have studied the effect of adding Pz and Pp to Na₂CO₃. The result showed that absorption rate of CO₂ was increased by adding these additives.
