Abstract
A centrifugal counterflow type contactor wherein the interior space of a drum carried by a rotating shaft has a predetermined axial width or the interior space of the drum is divided by at least one baffle plate mounted on the rotating shaft into at least two chambers each having a predetermined width; and a light liquid is introduced into said interior space or each chamber at positions adjacent to the radially outward end thereof while a heavy liquid is introduced into said interior space or each chamber at positions adjacent to the radially inward end thereof so that rapid rotation of the drum causes the radial counterflow contact between the light and heavy liquids. The extraction efficiency is equal to or higher than that of a corresponding prior art centrifugal contactor, and the solids in the liquids may be prevented from being accumulated in the counterflow region.
