Abstract. The method, its implementing device, and software have been improved, collectively designed to study the stages of the extraction process of target components from porous materials in real time. The updated software enables the determination of optimal operating modes and conditions for extraction processes, closely resembling actual process conditions. The proposed development can be used to study processes involving changes in the mass and/or volume of the porous solid being studied while suspended in a liquid.

Keywords: extraction, solid–liquid system, effective diffusion coefficient, porous materials, mathematical modeling, research complex
