چکیده انگلیسی
Hydrodynamic experiments were conducted in a microbore helix based passive mixer for the system of HNO3/30% TBP/n-dodecane under non-mass transfer conditions. Hold up and drop sizes were experimentally measured for an aqueous phase flow rate of 0.15-0.80Â mL/min and organic phase flow rate of 0.10-0.75Â mL/min for various A/O ratios from 0.2 to 5. Although a fine dispersion was generated in the mixer, it did not affect coalescence and clear streams emerged from exit points of a mini settler (â¼1.2Â mL). Due to smaller drop sizes generated, the observed specific interfacial area was huge and for the experimental conditions reported, it was ranged about 2.84Â ÃÂ 104 to 8.56Â ÃÂ 104Â m2/m3. It is of the same order of that observed in a 50-mm centrifugal extractor with identical aqueous-organic pair.
