Study on Scale-Up Criteria for Mixers in a Mechanically Agitated Mixer-Settler

摘要

We studied the problem of design scale-up of mechanically agitated mixers in box-type mixer-settlers in different extraction systems in batch-operated and continuous flow mixer-extractors. It was determined that the scale-up index n in the similarity scale-up equation ND/sup n/ = constant for mixer-extractors was equal to 0.87 to 0.88. This value is different from those obtained by other research workers and we carried out a preliminary theoretical analysis of these findings. It was determined that suitable n values are of great significance for determining design scale-up and operating conditions of mixer-extractors. (ERA citation 09:017072)
