“…Multiple transport mechanisms in series pose another challenge when pursuing a rigorous modeling technique, and Petruzzelli et al, McKevitt and Dreisinger give the most compelling evidence of this phenomenon. They show that the external (extraparticle) layer controls in the earlier stages of the transient, while towards the end control switches over to intraparticle diffusion.…”

A diffusion-based kinetic model for resin-based ion exchange is proposed that simultaneously describes extra-and intraparticle diffusion for the purpose of predicting batch transient adsorption rates during resin operation. The extraparticle diffusion is simulated through Newton's-law-of-cooling assuming a stagnant laminar layer, while the intraparticle simulation assumes a homogeneous internal pore environment and uses the Nernst-Planck equation to describe multi-ion diffusion. The key parameters of the model are the mass transfer coefficient, the intrinsic diffusivities of the adsorbing and desorbing ions and the equilibrium coefficient associated with the Mass-Action-Law, which is assumed to be applicable at the liquid/resin interface. A novel method is described to determine the critically important ion concentration at the interface from experiment. Kinetic tests are undertaken in a closed circuit system, adsorbing Na, Mg, and Ba ions separately onto gel type acid resin, and the simulation is fitted to the measured raw data using the Hook-Jeeves search algorithm. The intraparticle diffusivities of the three ions are hence measured and reported.

“…According to various authors, the carboxylic groups are mostly protonated at pH 1.3, as in the ACQ-and CA-treated wood leachates (McKevitt and Dreisinger, 2012;Mendes and Martins, 2004). This lowers the Cu affinity for the imminodiacetic acid group as well as its loading capacity on the resin.…”

“…Adsorption in stirred tank reactors (CSTR) in the form of resin in pulp (RIP) or carbon‐in‐pulp (CIP) is an economically attractive process for recovery of uranium, gold, and base metals (e.g. Cu and Ni), from their low grade ores. Typical concentrations of target metal ions in the RIP and CIP processes is in the (mg/L) range, and volume of the feed liquor tremendous; thus, attaining a reasonable throughput involves deploying of a countercurrent cascade, with 6–12 reactors in series .…”

Analytical and semi‐analytical kinetics models for design and optimization of double‐resistance resin in pulp and carbon in pulp processes with both reversible and irreversible nature

et al. 2018

The current study was aimed at developing a package of “model + algorithm” for the design of resin in pulp (RIP) and carbon in pulp (CIP) processes of gold, uranium, and base metals. For this purpose, we first formulated a double‐resistance model for irreversible adsorption (accompanied by chemical reaction) in CSTRs, and modified the McKay et al. semi‐analytical model for reversible uptake in a similar system. We then devised two algorithms for the design and optimization of reversible and irreversible RIP and CIP cascades. The developed algorithms were applied on the extraction of copper, uranium, and gold. The packages are able to specify the optimum number of stages, reactor volume (V), resin flow rate (m.), and resin hold up (φs). This shows an evident advantage over the McCabe‐Thiele method, whose only result is the number of stages. The new methods have only two adjustable parameters of diffusivity (Deff) and liquid film coefficient (k), whose determination can be carried out through simple batch experiments. As an additional work, this study also presents a method for mathematical troubleshooting for the Mc Kay et al. model.
