A Dynamic Study of the Extraction of Rare Earth Chloride D2E1IPA - EC1 in a Multistage Mixer-Settler Extractor

摘要

The flow patterns within a pump mix mixer-settler extractor are studied photographically and visually. One is injected into the pump mixer and followed through the various portions of the equipment. These results are analyzed to give both a quanitative and qualitative measure of the flow within a single stage.nA mass transfer mechanism is derived base on a pseudo distribution constant and a pseudo first order rate constant. These constants are adjusted to give both the proper output concentrations, and stagewise concentrations of the proper for a.nThe results of both these studies are progressed on an IBM 360 model 65 digital computer. The results obtained by this computer simulation of startup to steady state are compared to experimental data. The comparison shown very close agreement.
