ColHySE: An advanced column hydrodynamic-based model for solvent extraction

An original one dimensional population balance model (PBM)-based of liquid–liquid extraction columns is reported. Compared to existing simulators, ColHySE implements a more realistic description the flow patterns in contactor, and predicts its effect on local droplet–droplet interactions (i.e. breakage coalescence rates). Proper turbulent properties, extracted from single-phase CFD simulations, are used source terms PBM evaluate locally inhomogeneous rates, using averaged Coulaloglou Tavlarides kernels (Castellano et al., 2018). The sensitivity predicted droplets mean diameter, d32, holdup, φ, parameters empirical phenomenological models, hand, operating conditions column, other was studied. Although some parts must be refined, an experimental validation remains necessary, results confirm that 1D-PBM methodology relevant for predicting interfacial area pulsed column as function geometry, hence highlighting relevance study hydrodynamic stability tendency flooding. analysis has moreover highlighted needs improved slip velocity model.
