수용액에서의 질소산화물 흡수 ; II. 다공판탑에서 NOX 흡수에 의거 생성되는 HNO3와 HNO2 농도
NOx Absorption into Agueous Solutions;II. HNO3 and HNO2 Concentration Produced by NOx Absorption for a Sieve Tray Column
다공판탑에서 물에 의한 질소산화물의 흡수결과 생성되는 액상의 HNO3와 HNO2 농도를 측정·분석하였다. NOX 흡수가 기상의 N2O4 농도에 지배된다고 가정한 제1보와는 달리 기상의 N2O4 뿐 아니라 N2O3의 농도가 NOX 흡수를 지배한다고 가정하여 전개한 흡수모델로부터 얻은 이론값과 실험치를 비교한 결과 비교적 잘 일치하는 경향을 나타내었으며, HNO2는 농도가 높을수록 급격히 분해하는 경향을 나타내었다.
The concentrations of HNO3 and HNO2 in liquid phase produced from the absorption of NOx into water in a sieve tray column were measured and analyzed.
The mathematical model in the Part II of this study was developed in the assumption that the absorption of NOx would be governed by the concentration of gaseous N2O3 as well as the concentration of gaseous N2O4, but in the Part I, the concentration of gaseous N2O4 had been considered as the only active parameter in the absorption process of NOx.
With the comparison between the theoretical values from this mathematical model and experimentals, they were in good agreement and HNO2 tended to be dissociated rapidly at the higher concentration of HNO2.
