Abstract
혼합강도의 영향을 크게 받는 혼합조-분리조에서 액-액 혼합물의 분리현상을 실험적으로 고찰하였다. 실험계로서는 이성분 물-용매（노르말헥산, 이소옥탄, 에틸아세테이트와 노르말헥산）이다. 회분 실험의 결과로부터 유기물 체류량이 0.30∼0.50인 범위에서 평균액적크기, Weber수와 관련된 다음과 같은 관계식을 얻었다.
do/D = 0.026（1+20Φ）We0.6
또한, 다중입자계의 분리특성을 나타내는 상관식이 연속상에 대한 상대속도를 근거로 다음과 같이 유도되었다.
ReΦ=1.11x10-12BoΦ1.25Mo1.60（1-Φ/1+Φ1/3）2.60
do/D = 0.026（1+20Φ）We0.6

The study on liguid-liguid separation characteristics in a mixer-settler system which is strongly influenced by mixing intensity was conducted experimentally. The experimental systems considered here are binary distilled water-organic solvent （n-heptane, iso-octane, ethyl acetate or n-hexane） systems. By performing batch tests, the relationship between the mean drop size and the Weber number was generated by
do/D = 0.026（1+20Φ）We0.6
where 0.30≦Ֆ≦0.50. Also, the separation characteristics for multiparticle systems were presented, based on the relative velocity of the continuous phase:
ReΦ=1.11x10-12BoΦ1.25Mo1.60（1-Φ/1+Φ1/3）2.60
do/D = 0.026（1+20Φ）We0.6
where 0.30≦Ֆ≦0.50. Also, the separation characteristics for multiparticle systems were presented, based on the relative velocity of the continuous phase:
ReΦ=1.11x10-12BoΦ1.25Mo1.60（1-Φ/1+Φ1/3）2.60
