Abstract
Liquid—liquid extraction apparatus includes a separator tank rotatable about an axis extending through the tank, a tank inlet for a mixture of two liquids of different densities and which are substantially insoluble in each other, a tank outlet on the axis of rotation for the light liquid, and a tank outlet spaced from the axis of rotation for the heavy liquid. In terms of method, a mixture of the two liquids is rotated about an axis extending through the mixture to cause the light liquid to concentrate at the axis of rotation, and to cause the heavy liquid to concentrate at the periphery of the rotating liquid. The light liquid is removed from the body of liquid along a flow path co-linear with the axis, and the heavy liquid is removed from the periphery of the rotating body of liquid.
Claims6
Apparatus for separating a mixture of two liquids of different densities and which are substantially insoluble in each other, the apparatus comprising:
- a separator tank rotatable about an axis extending through the tank;
- a tank inlet for the two mixed liquids;
- a tank outlet substantially on the axis for the light liquids;
- a plurality of tank outlets for the heavy liquid, the plurality of outlets for the heavy liquid being spaced different distances from the axis, the outlets for the liquids being axially spaced from the tank inlet;
- and
- a deflection baffle in the tank between the light liquid outlet and the outlets for the heavy liquid, the deflection baffle substantially lying in a plane transverse to the axis so the baffle has an outer edge spaced from the tank and located a greater distance from the axis than the outlets for the heavy liquid.
