A packed tower is modelled transiently for fluid-solid reactions. Heat and mass transfer are considered, with allowance for structural changes. The Knudsen, molecular and bulk flow terms are accounted for in the packed tower and within the pellets of the packing. Homogeneous, heterogeneous and catal

โฆ Synopsis
A model for mass transfer in packed towers is proposed which considers local transfer conditions by taking into account the liquid residence time distribution function. This model valid when the mass transfer resistance is in the liquid phase, describes well physical and chemical absorption data, using parameters independent from the liquid Row rate.
The calculated rates of chemical absorption were found dependent also on the absorbing capacity of the liquid phase, as experimentally determined by other Authors[3].
