摘要： A process for fractional crystallization of paraffin from mineral oil based and synthetic crude paraffin, wherein crude paraffin having a high oil content is crystallized in a crystallizer equipped with perforated metal sheets (31) extending in a zig-zag in the spaces between the heat exchanger surfaces (39). The paraffin-containing melt is only solidified to an extent such that the fractions and oils for discharge remain liquid and are run off without total solidification of the melt. The perforated sheets (31) support the layers of crystals (43) and during sweating the paraffin is detached in strips from the heat exchanger surface (39) and is adapted to rest on the sloping perforated sheets (31). The inclination of the perforated sheets (31) guides and moves the paraffin strips (53), so that the paraffin strips remain in contact with the heat exchanger surfaces (39) while being pressed by their own weight along the inclined surface (30) towards the heat exchanger surfaces (39).

摘要： In the process according to the invention for fractionating substances, particularly paraffins, oils, fats and waxes, which, when crystallized, have poor adhesion to the substantially vertical crystallization surfaces (39) of a crystallizer, screen-like supporting structures, e.g. perforated metal sheets (31) bent in a zig-zag, are disposed between the crystallization surfaces (39) of a crystallizer. The crystals (51) becoming detached from the crystallization surfaces (39) during the sweating phase are left suspended in horizontal strips in the triangular zones (41) on the perforated sheet (31) and remain in thermal contact with the crystallization surface (39) and sweat out the liquid phase (55). The mother liquor (55) drips off, in some cases also between the crystals (51) and the crystallization surface (39), with the result that drip channels are melted by the heated mother liquor and thus opened.
