Abstract

We develop a mathematical model for filtration in a cylindrical column packed with a porous material. The base model involves coupling an advection-diffusion equation to a sink term which represents the sorption and is appropriate when trace quantities are removed from the fluid. This is then extended to include the variation of velocity and pressure, which is appropriate for the removal of significant quantities, and leads to a system of five coupled equations. For the case of CO2 removal we are able to reduce the complexity of the equations and to derive an analytical expression for the breakthrough curve. This expression is then verified against experimental data for the adsorption of CO2 from gas and antibiotics from water. Finally, we show how the work may be modified to deal with certain extraction processes, where a clean fluid is used to remove material from the porous matrix, such as lanolin from wool.
