Hybrid Multiphase CFD Solver for Coupled Dispersed

The flows in stage-wise liquid-liquid extraction devices include both phase segregated and dispersed flow regimes. As a additional layer of complexity, for extraction equipment such as the annular centrifugal contactor, free-surface flows also play a critical role in both the mixing and separation regions of the device and cannot be neglected. Traditionally, computional fluid dynamics (CFD) of

CFD SIMULATION OF A SOLVENT EXTRACTION PUMP MIXER …

The mixer unit comprises of a square mixer box (of dimensions 450mmx450mmx450mm) equipped with a Lightnin R320 pump-mixer (of diameter 230 mm and positioned about 5 mm above the false bottom). The mixer has been modelled with an impeller speed of 200 rpm (tip speed of 2.4 m/s). In this work, only the pump-mixer region has been simulated.

Mixer-Settler Based on Phase Inversion: Design of the

Apr 28, 2006 · The aim of this work is to improve the separation efficiency in the case of liquid−liquid dispersions using a new type of mixer-settler design called MSPI (mixer-settler based on phase inversion) and a so-called solvent assisted method. The phase inversion is used to decrease the distance between the drops of the disperse phase and the interface in spherical decanters called carrier drops
