Abstract
This invention concerns an improved process for separating one crystallize component from a liquid containing a plurality of components, which comprises passing a stream of said liquid successively through at least part of a series of zones of successively lower temperatures including the zone of lowest temperature, so as to induce the formation of crystals of said one component in each of said zones, passing the crystals formed in each of said zones in a direction countercurrent to the direction of the stream of liquid through at least part of said zones, including the zone of highest temperature, separating the crystals present in the zone of highest temperature from their mother liquor and recovering at least part of these crystals, separating the crystals in the zone of lowest temperature from their mother liquor and recovering that mother liquor, and recirculating part of said crystals present in one zone, from that zone to a zone of lower temperature. This invention also concerns an apparatus for carrying out the process.
