LIQUID-LIQUID MINIPLANT EXTRACTOR ― A NOVEL TOOL FOR PROCESS DESIGN

摘要

Experimental studies using a 32 mm diameter miniplant extractor are presented including a description of the auxiliary equipment and measuring techniques for hydrodynamic data acquisition. In single backmixing experiments linear relationships were found between the dispersion coefficient and stirrer agitation speed and the dispersion coefficient and the flow rate. Dispersion coefficients calculated using CFD agreed well with experimentally measured values. It was shown that CFD contributes to a better understanding of the basic mechanisms governing the hydrodynamics of liquid-liquid extraction.
