Modeling of Mass Transfer Process in a Fixed Layer of the Adsorbent in Viscous Media
AbstractA mathematical model of adsorption clarification of vegetable oils in a fixed layer of the adsorbent is developed. An equation for the penetration coefficient is proposed based on the extracted component mass transfer regularities analysis depending on the convective flow of a viscous medium, as well as internal diffusion. An equation for calculating the adsorbent layer specific surface area that takes into account connection of the flow through the layer with differential pressure is calculated. A differential equation for the volumetric component flow through the adsorbent layer that takes into account change in the extracted substance concentration is derived on the basis of the theory of mass transfer through porous layers. A solution of this equation allows obtain an expression to determine the coefficient of trapping the layer. An expression to change the trapped component concentration is calculated.
