Consideration is given to a model (suitable for description at large times) for analysis of the heat- and massexchange processes of a porous body with two types of pores. Specifically, we are dealing with impregnation (in a sense, with the process of extraction, its converse). The solution of the problem with the most typical supplementary conditions is obtained; the kinetic impregnation (withdrawal) function and the density of the substance flux from the body are found for this problem.
