충전된 가스흡수탑 내의 유효물질 전달면적과 물질 전달 계수
Effective Mass Transfer Area and Mass Transfer Coefficient in a Packed Gas-Absorber
초록
충전된 가스흡수 탑내에서의 유효 경계면적과 액측 물질전달 계수를 결정하기 위해서 비가역 일차반응을 일으키는 흡수계에 대해서 관찰하였다. 흡수탑에는 여러 가지 다른 모양과 크기의 충정물을 충전시키고, 또 액체의 종류와 성질을 여러 가지로 바꿔서 실험을 하여 이들의 변수가 유효경계 면적과 액측 물질전달계수에 미치는 영향을 고찰하였다. 이들 시험결과를 분석하여 무차원군 사이의 상관식을 얻었으며, 그 상관식은 다른 연구 결과에도 잘 적용됨을 알았다.
Chemical absorption with irreversible first order reaction was used to determine the effective interfacial area and the liquid-side mass transfer coefficient in a packed gas-absorber. Experiments were undertaken for packings of different shapes and sizes and for several kinds of liquid with various properties so that their effects on the effective interfacial area and the liquid-side mass transfer coefficient are observed.
Correlations were obtained in terms of dimensionless groups through the regression analysis of the experimental results. The results of this work were compared with the other results, and a good agreement was observed.
