Abstract

용매추출에 사용되는 다단 Pump-Mix Mixer-Settler의 유동특성을 수학적 모델을 세워 표시하였다. 여기서 모델은 혼합조를 완전혼합조로, 정치조를 CSTR재순환을 하는 플라그흐름으로 가정하였으며 모멘트와 시간지연을 일치시켜 모델보조변수를 구했다. 물-석유계에서 충격응답으로 각상에 대해 체류시간 분포함수를 구하여 모델식과 비교한 결과 본 모델이 실험 오차범위내에서 실험치와 잘 일치함을 보였고 지금까지 제시된 모델들은 이 장치계의 동특성을 너무 단순화시켜 표시하고 있음을 알았다.
The hydrodynamic characteristics of Multistage Mixer-Settlers were studied by establishing a mathematical model based on the assumptions of complete mixing in the mixer and plug flow with CSTR recirculation in the settler. The model parameters were determined by the moment and time lag matching and experiments were carried out with a water-kerosene system by obtaining residence time distributions for both phases using impulse response technique. The suggested model well predicted the experimental results within the experimental error range, while the other existing models were found to be too idealized to depict the dynamic characteristics of this equipment.
