Abstract
The transport of highly concentrated solutions in porous media was studied both numerically and experimentally. For numerical modeling we used a mobile-immobile (MIM) approach that considers clogging phenomenon. The impurity transition between the mobile and immobile phases was defined by second-order Langmuir kinetics. Kozeny-Carman expression modeled the clogging. The model has four phenomenological parameters which cannot be measured directly. These parameters were identified by minimization of the cost function, which is the squared distance between experimental and numerical data. Dependencies of concentration and mass flux at the outlet were analyzed. Twenty-five different experiments were conducted, and it was shown that transport parameters do not depend on impurity concentration or pressure drop between the ends of the column.
