ABSTRACT:
Method and apparatus for separation of mixtures wherein a mixture is cooled very slowly in a quiescent, nondisturbed condition to produce large dendritic crystals of solidified solvent, then heated very slowly while liquid of high solute concentration is drained from the large interstices between the crystals, the cooling and reheating being effected by slowly conveying containers of mixture through a long heat transfer conduit or tunnel having a central refrigeration zone; parallel trains of containers preferably travel through the conduit in opposite directions. The residence time of the mixture in traveling through the conduit or tunnel will be of the order of many hours or a few days, depending upon many factors, and in a large industrial installation the length of a pass through it will be several hundred feet; such factors are interrelated to the quantity and compositions of mixtures being processed.
