On the use of equilibrium models to describe dynamic adsorption regimes
M. Calvo-Schwarzwalder, A. Valverde, A. Cuesta López +3
We present a column adsorption model that couples a Pseudo-First-Order (PFO) kinetic formulation with the Sips isotherm framework. Using a traveling wave approximation, we derive a…
Modelling large mass removal in adsorption columns
Timothy G. Myers, Marc Calvo-Schwarzwalder, Francesc Font +1
A mathematical model is developed to describe column adsorption when the contaminant constitutes a significant amount of the fluid. This requires modelling the variation of pressur…
A mathematical model for contaminant adsorption in packed columns using nonlinear mass transfer
F. Font, A. Estop, M. Calvo-Schwarzwalder +2
We propose a mathematical model for describing column adsorption processes where large amounts of contaminant are removed from a carrier gas. The large mass loss causes velocity an…
An analytical investigation into solute transport and sorption via intra-particle diffusion in the dual-porosity limit
Lucy C. Auton, Maria Aguareles, Abel Valverde +2
We develop a mathematical model for adsorption based on averaging the flow around, and diffusion inside, adsorbent particles in a column. The model involves three coupled partial d…
Modelling mass transfer from a packed bed by fluid extraction
Timothy G. Myers, Abel Valverde, Maria Aguareles +2
A mathematical model describing the erosion or leaching of a solid material by a flowing fluid in a column is developed. This involves an advection-diffusion equation coupled to a…
The Stefan problem with variable thermophysical properties and phase change temperature
Timothy G. Myers, Matthew G. Hennessy, Marc Calvo-Schwarzwälder
In this paper we formulate a Stefan problem appropriate when the thermophysical properties are distinct in each phase and the phase-change temperature is size or velocity dependent…
