Abstract
Apparatus for solvent extraction of a mother liquor with a solvent that is immiscible with and has a different specific gravity than the mother liquor, is disclosed. Means are provided for introducing into an extraction chamber, the solvent, the mother liquor and a carrier gas. Such means simultaneously serve to atomize the solvent and the mother liquor and disperse same in the carrier gas whereby upon introduction a cloud phase is produced in the chamber. The introducing and simultaneously atomizing is carried out through one and the same spray nozzle. Condensation means are arranged in the extraction chamber and function to terminate the cloud phase and produce a condensed extracted mother liquor phase and a condensed solvent phase containing the substance to be extracted. Means are provided for separating the condensed extracted mother liquor phase from the condensed solvent phase on the basis of the different specific gravities of same.
