“…Aoun‐Nabli has proposed a numerical correlation for the most important parameters of the flow based on the standard k – ϵ turbulence model (pressure drop, axial dispersion coefficient, turbulent dissipation, etc.). More recently Bujalski et al have measured the velocity field inside the column by the PIV and LDV techniques. They have compared their results with simulations conducted with the low‐Reynolds k – ϵ turbulence model.…”

International audienceThe pulsed column is a widely used technology for liquid-liquid extraction processes in various industries. In this work, the use of this technology has been extended to perform continuous precipitation. An original process of continuous precipitation in emulsion in a pulsed column is thereby developed. A thorough understanding of the behaviour of the dispersed phase inside the column helped to achieve process optimisation and is the purpose of this paper. In this aim, a coupled computational fluid dynamics (CFD)-population balance equation (PBE) approach was developed for the simulation of this original process, and allows the determination of the mean droplet size, which is a key parameter. On one hand, breakup and coalescence kernels for the PBE were selected by performing homogenous type experiments in a stirred tank reactor. The parameters of those kernels were adjusted by fitting the models' parameters to the measured droplets size distribution (DSD) in the stirred tank. One another hand, the continuous phase flow inside the pulsed column was investigated by CFD and has been validated using particle image velocimetry (PIV) data. The latter helped us to choose the best turbulence model representing the flow inside the pulsed column. Finally, the coupled CFD-PBE model was implemented using the quadrature method of moments (QMOM) in the CFD code ANSYS-Fluent (R) to determine the mean droplet size inside the column

“…Recently, the availability of liquid-liquid extraction is re-acknowledged and has moved into the limelight with the recovery and recycling of rare metals from industrial wastewaters and processing solutions. [1][2][3][4][5] As liquid-liquid extraction apparatuses of industrial scale, mixer-settler, [6][7][8][9][10][11][12] centrifugal extractor, [13][14][15][16] spray extraction column, [17][18][19][20] and pulsed or reciprocating-plate plug-flow extraction column [21][22][23][24][25][26][27][28][29][30][31][32] are known. In order to achieve high performance liquid-liquid extraction, it is favorable to mix aqueous and organic phases into an emulsion continually.…”
