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…
Mathematical modelling of flow and adsorption in a gas chromatograph
A. Cabrera-Codony, A. Valverde, K. Born +2
In this paper, a mathematical model is developed to describe the evolution of the concentration of compounds through a gas chromatography column. The model couples mass balances an…
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…
Mass transfer from a fluid flowing through a porous media
T. G. Myers, F. Font
A mathematical model is developed for the process of mass transfer from a fluid flowing through a packed column. Mass loss, whether by absorption or adsorption, may be significant.…
Mathematical modelling of carbon capture in a packed column by adsorption
T. G. Myers, F. Font, M. G. Hennessy
A mathematical model of the process of carbon capture in a packed column by adsorption is developed and analysed. First a detailed study is made of the governing equations. Due to…
A slip-based model for the size-dependent effective thermal conductivity of nanowires
M. Calvo-Schwarzwälder, M. G. Hennessy, P. Torres +2
The heat flux across a nanowire is computed based on the Guyer-Krumhansl equation. Slip conditions with a slip length depending on both temperature and nanowire radius are introduc…
