FIELD: chemical engineering. SUBSTANCE: invention aims at conducting processes in conditions of countercurrent contact between dispersion in the form of dense suspension and dispersion medium. Method consists in that contact of phases is continuously accomplished by displacing dispersion phase with 75-85 vol.% concentration within half-period of pulsation with velocity exceeding that of fluidization of moving dispersion medium within the same period. EFFECT: intensified processes in heterogeneous systems. 1 dwg
