“…They have taken into account the external mass transfer, the internal diffusion transport through the pores, the chemical reactions, the heat of reaction and heat transfer due to effective conduction in the entire solid matrix. Dussoubs et al have developed a similar model for the production of uranium tetrafluoride. Simultaneous heat and mass transfer between air and soybean seeds in a countercurrent moving bed dryer has been studied by Lacerda et al.…”

A mathematical model for a moving bed reactor with embedded heat exchanger has been developed for application to solid sorbent-based capture of carbon dioxide from flue gas emitted by coal-fired power plants. The reactor model is one-dimensional, non-isothermal, and pressure-driven. The two-phase (gas and solids) model includes rigorous kinetics and heat and mass transfer between the two phases. Flow characteristics of the gas and solids in the moving bed are obtained by analogy with correlations for fixed and fluidized bed systems. From the steady-state perspective, this work presents the impact of key design variables that can be used for optimization. From the dynamic perspective, the article shows transient profiles of key outputs that should be taken into account while designing an effective control system. In addition, the article also presents performance of a model predictive controller for the moving bed regenerator under process constraints.

“…The example of the application of Sohn's law by Patisson et al and Dussoubs et al is noteworthy in that the law was found to have many advantages over other models when simulating a complex reaction system in a multiparticle moving bed furnace. Selected examples of the application of Sohn's law are shown below.…”

Part 1 of this series covered the reaction of a non-porous solid. [1] In this Part 2 of the series, we present a review on the reactions involving a porous solid, which is the most widely encountered type of fluid-solid reactions. The major difference between the reactions of a non-porous and a porous solid is the fact that in the latter, the fluid reactant can reach the interior of the porous solid through the pores even through a portion that contains unreacted solid reactant. The rate expression for the solid at any point depends on, among others, how the area of reaction interface changes with the conversion of the solid. The governing equations, in general, require numerical solution. In this article we describe an approximate closed-form solution to this problem that yielded Sohn's law of additive reaction times. The result is simple to apply and has many useful features, especially for the design and modelling of a multi-particle system.
