초록

다단탑의 단효율에 미치는 액체의 비말동반과 방울흐름의 영향을 이론적으로 고찰하였다. 판위의 물질수지식에서 액상의 진행 방향 뿐 아니라 수직 방향으로도 농도분포가 존재할 경우의 모델을 분석하고 일부결과를 그림으로 나타내었으며 기존실험결과와 비교하였다.

The effects of liquid entrainment and weeping on the plate efficiencies of the multistage column are theoretically analysed. The presented model assumes the existence of concentration profile both in the liquid flowing direction and in the radial direction. Sample results are shown graphically and compared with the experimental data reported in the literatures.
