A Diffusion Model of Bath Washing Extraction of a Porous Material and an Evaluation of Its Conformity with the Real Process
Fialka M., Charvátová H.
Abstract:
In this paper, the focus is on the definition of the mathematical conditions needed to ensure that the presented diffusion model of the extraction of a bound biopolymer impurity into the wash liquid during the bath-washing process of that porous material will be in satisfactory accordance with the real washing process from a certain calculated time. The numerical computation of the space-time volume concentration field course in the porous material by means of a diffusion model, which is mentioned in the contribution, is very helpful for the optimization of the washing processes in the chemical and tanning industries.
Keywords:
