초록

본 연구에서는 고밀집 섬유체에 의한 정적 액-액 접촉기에 대한 이론적 모델링을 통하여 섬유체 접촉기 내부에서의 물질 이동과정과 각 상에서의 축 방향 농도분포 해석이 수행되었고, 여러 운전 조건하에서 출구 농도를 예측하여 실험치와 비교하였다. 본 섬유체 액-액 추출기는 그 구조적 특성 때문에 축 방향 분산이 없는 플러그 흐름 모델로 완벽하게 묘사될 수 있었으며 data fitting을 통해 결정되어 모델식에 적용된 물질전달 계수와 섬유체 추출기 축 방향 반위 길이 당 물질전달 면적의 곱의 항인 k_aσ은 그 섬유체 추출기의 고유 특성 값으로 사용될 수 있었고, 그 값은 약 0.0327㎠/sec이었다.

Mass transfer mechanism and concentration profiles in the axial direction at each phase were analyzed and simulated by a theoretical modeling on a liquid-liquid static contactor using highly packed fiber bundle. The concentrations at the end of the fiber extractor calculated at several operational conditions were compared with experimental results. The fiber extractor could be completely predicted by a plug flow model without axial dispersion. A parameter used in the model equations, k_aσ called the product of mass transfer coefficient and mass transfer area per unit length of the fiber extractor in the axial direction, which was determined by a curve-fitting, was confirmed to be a unique characteristic value of the fiber extractor, and was about 0.0327 ㎠/sec.
