MODELING OF THE EXTRACTION OF A TARGET COMPONENT FROM BODIES OF SPHERICAL SHAPE IN A SEMICONTINUOUS PROCESS

A problem of extraction of a target component from bodies of spherical shape in an apparatus of semicontinuous action (periodic for the solid phase and continuous for the liquid phase), in which the liquid phase is completely mixed, has been formulated and solved analytically. The kinetics of the process has been analyzed with a numerical method at different values of the specifi c fl ow rate of the liquid phase. Recommendations have been given on the use of the solution obtained for calculating the kinetics of extraction of low-molecular-weight compounds from the granules of fi berizing polymeric materials.
