체단탑에서의 이성분계 혼합물의 거품발생현상에 관한 해석
Analysis of Foaming Phenomena of Binary Mixtures in Sieve Plate Columns
증류나 흡수조작 중에 발생되는 거품을 해석하기 위해서 직경이 2 in인 체단탑을 이용해서모의 실험을 행하였다. 공기의 유속변화에 따른 거품의 높이 변화를 측정하였으며 액체의 유량을 변화시키면서도 실험을 하였다. 표면장력, 밀도, 점도와 같은 물리적 성질이나 기체속도, 액체유량과 같은 조업조건이 거품의 높이에 미치는 영향에 대해서 알아보기 위해서 차원해석을 하였고, 차원해석의 결과로부터 거품의 높이를 Weber수나 Reynolds수와 같은 무차원수로 나타낼 수 있었다.
For analysis of the foaming in distillation and absorption tower the simulated distillation in a sieve tray column was performed. The 2 inch-diameter sieve tray was used. Foam height was measured for various air flow and liquid flow rates. Foam height data were correlated by dimensional analysis. The physical properties such as surface tension, density and viscosity and the operating such as vapor velocity and liquid flow rate were used as variables. The results of dimensional analysis show that the foam height could be expressed as a function of Weber number and Reynolds number.
