Mixer-settler extractor

Abstract

Abstract EXTRACTING OPERATION BETWEEN TWO OR MORE LIQUIDS MUTUALLY MISCIBLE ONLY INCOMPLETELY IS MUCH FACILITATED BY EMPLOYING AN APPARATUS COMPOSED OF A PLURALITY OF SUPERIMPOSED UNIT STAGES, ANY GIVEN ONE OF WHICH IS EQUALLY DIVIDED INTO A CYLINDRICAL MIXING COMPARTMENT WHICH IS VERTICALLY STACKED WITH MIXING COMPARTMENTS OF THE REMAINDER OF THE UNIT STAGES IN A STAGGERED RELATIONSHIP AND PROVIDED WITH A MEANS OF AGITATION AND AN ANNULAR CYLINDRICAL MIXING COMPARTMENT ECCENTRICALLY SURROUNDING THE MIXING COMPARTMENT BY A VERTICAL PARTITION HAVING A PORT WHICH PROVIDES THE COMMUNICATION BETWEEN THE TWO COMPARTMENTS IN THE SAME STAGE, IN VERTICAL ALIGNMENT WHICH CONSTITUTES A GENERALLY CYLINDRICAL COLUMN. SAID ECCENTRIC SHAPE OF THE ANNULAR SETTLING COMPARTMENTS AFFORDS AN IMPROVED FLOW OF LIQUID WITHIN THE COMPARTMENTS AND SAID STAGGERED DISPOSITION OF THE COMPARTMENTS PERMITS THE PROVISION, WITHIN THE SETTLING COMPARTMENTS, OF PROJECTING DOWNTAKE AND SUCTION PIPES CONNECTED TO PORTS WHICH OPEN AT THE MIXING COMPARTMENTS WHICH ALLOW THE DIRECT AND SMOOTH INTRODUCTION OF LIQUIDS FROM THE SETTLING COMPARTMENTS OF THE UNIT STAGES IMMEDIATELY ABOVE AND BELOW THAT GIVEN STAGE INTO THE MIXING COMPARTMENT OF THAT STAGE.
