Effect of phase dispersion and mass transfer direction on steady state RDC performance using population balance modelling

A pseudo-3D model with 3D accuracy and 2D cost for the CFD–PBM simulation of a pilot-scale rotating disc contactor

“…Attarakih et al (2004Attarakih et al ( , 2006aAttarakih et al ( , 2006bAttarakih et al ( , 2006cAttarakih et al ( , 2012Attarakih et al ( , 2013 developed the PBM codes, including the liquid-liquid extraction column module (LLECMOD) and the particulate population balance laboratory (PPLAB) for extraction columns, in which simplified hydrodynamic models were employed to solve population balance equations. The codes were successfully applied to simulate different extraction columns such as RDC, Kühni column and pulsed column Jaradat et al, 2010;Jaradat et al, 2011;Attarakih et al, 2012;Jildeh et al, 2013;Jildeh et al, 2014;Attarakih et al, 2015). Their results showed that the PBM codes are able to reasonably simulate the holdup profiles, droplet Sauter mean diameter and concentration profiles.…”

LLECMOD: A Bivariate Population Balance Simulation Tool for Pulsed Liquid-Liquid Extraction Columns

“…The models of both columns are integrated into the existing program: LLECMOD [5,6], which can also simulate agitated extraction columns (RDC and Kühni). LLECMOD simulates steady state and dynamic behavior and takes into account the effect of dispersed phase inlet (light or heavy phase is dispersed) and the direction of mass transfer (from continuous to dispersed phase and vice versa) [7]. Therefore, scale-up studies and performance simulations of agitated and non-agitated extraction columns based on population balance modeling can thus be carried out successfully.…”

Mass transfer efficiency of a tall and low plate free area liquid pulsed sieve-plate extraction column

“…However, due to the complex nature of the extraction process, the design procedures and practices (correlations) are not yet well established and usually pilot scale testing is required for such columns. Although some advanced modeling techniques [29][30][31][32][33][34] are currently acclaimed, however, for the reliable design strategies and computer methods to be well developed, more of such experimental studies (relationships among the column efficiency and operating parameters) on a pulsed sieve-plate column have to be accomplished for the various geometries and liquidliquid systems. The review of the literature suggests that the dispersed phase holdup and mass transfer performance are generally studied for short columns with a few number of plates and with plate free area greater than 19%.…”
