초록
화력발전소에서 배출되는 배연가스에서의 CO2 가스 흡수를 목적으로 sodium glycinate계 흡수제를 개발하기 위하여 sodium glycinate의 순수 및 수용액의 물성인 용해도, 증기압과 비점, 열전도 및 증발 잠열을 측정 또는 추산하였다. 용매인 H2O 25 g에 대한 sodium glycinate의 온도별 용해도는 y = 0.3471x + 20.993의 1차 함수 관계로 증가하였다. Sodium glycinate 10 wt％, 20 wt％, 30 wt％, 40 wt％, 50 wt％, 60 wt％ 수용액의 증기압과 비점을 측정하고, Antoine 상수를 구하였으며 Clausius- Clapeyron 식을 이용하여 증기압 측정값으로 증발 잠열을 구하였다. Sodium glycinate 분체의 열전도도 측정은 분체를 disk판으로 성형한 후, 고체 열전도도 측정 장치로 측정하였으며 그 값은 1.0933 kcal/m·hr·°C 이었다.
Aqueous solution of sodium glycinate was checked as a suitable CO2 absorbent from the flu gas in the thermal power plant. For this purpose, solubility, vapor pressure, latent heat of vaporization and thermal conductivity were determined for pure and aqueous solution of sodium glycinate. The solubility of sodium glycinate in the solvent, 25 g of H2O, was increased with increasing the temperature and their relation was represented as a first order equation of y = 0.3471x + 20.993. The vapor pressure for 10 wt％ to 60 wt％ of aqueous sodium glycinate solution were determined and the latent heat of vaporization of each aqueous solution was calculated from measured vapor pressure using Clausius-Clapeyron equation. Besides, thermal conductivity of sodium glycinate powder was also determined and it was 1.0933 kcal/m·hr·°C.
