CFD modelling of pulsed sieve plate liquid extraction columns using OPOSPM as a reduced population balance model: hydrodynamics and mass transfer

01.Jan.2018

​A reduced coupled 2D-CFD and Population Balance Model (PBM) framework (Alzyod et al., Comput. Aided Chem. Eng., 40, 61-66) is extended to model the mass transfer behaviour of pulsed sieve plate liquid extraction columns. The Euler-Euler approach is used to model the two phase flow inside the column, while the One Primary One Secondary Particle Method (OPOSPM), the simplest form of SQMOM, is utilized as a reduced population balance solver. The proposed framework is numerically tested and the results are compared with the published experimental data. The required breakage and coalescence parameters to perform the 2D-CFD simulation are estimated using PPBLab software, where a 1D-CFD simulation using a multi-sectional gird is performed. A very good agreement is obtained at the experimental and the numerical validation levels.
