EFFECT OF PULSATORY MODE OF LIQUID SUPPLY ON THE KINETICS OF MASS-EXCHANGE WITH THE SOLID-PHASE

The effect of the pulsatory mode of liquid supply on the kinetics of d issolution and extraction of a solid soluble component from a porous p article has been studied in the approximation of a model unit mass-exc hange cell that is part of a dense moving bed of granular material and consists of a particle having the most typical size and a solution, w ith a phase volume ratio of these corresponding to the moving dense gr anular bed. Mathematical models are presented that describe both proce sses during the supply and pause intervals.
