    摘要: The invention is directed to an improvement in operation of wash columns, and more in particular to an apparatus for separating solid particles from a slurry and to a process for separating solid particles from a mother liquor slurry. The apparatus of the invention comprises a wash column (1), which comprises a melting circuit (8,10,11,21), wherein means (22,23) are present to introduce a compound or composition to said wash column between a wash front (6b) formed in said wash column in operation and a product outlet and/or in the melting circuit. The process of the invention comprises separating the liquid from the solid particles by filtration with the aid of at least one filtering element (4), while a packed bed of solid particles coming from the mother liquid slurry forms near said filtering element (4), and wherein a wash front (6b) forms which is obtained by bringing a washing liquid in counter current to the solid particles in the bed, the bed being subjected to a movement in the direction of said wash front (6b), while a product stream comprising the material of said solid particles is obtained by continuously discharging a portion of said washing liquid, wherein a portion of said bed is continuously disintegrated, characterized in that a compound or composition is introduced into said wash column (1) between the wash front (6b) and a product outlet and/or in a melting circuit (8,10,11,21), and wherein the introduction of the said compound or composition decreases the equilibrium temperature of the contents of the melting circuit (8,10,11,21), further characterized by the feature that the introduced compound or composition is completely miscible with the product suspension and/or molten product being present in the said melting circuit (8,10,11,21).

    摘要: In order to separate metals and/or metal alloys of different melting points from one another, a mixture of these metals and/or metal alloys is brought to a temperature at which the metal or the metal alloy of relatively low melting point is molten and the metal or the metal alloy of relatively high melting point is in the solid state. The solid constituents are separated from the melt, use being made of washing column with at least one filter which withstands the temperature of molten metal. Each of the filters is arranged in the wall of a separate pipe which extends through the washing column. The mixture is fed to one end of the washing column and moves along the pipe or pipes, towards means arranged at the opposite side of the washing column for removing solid crystalline material. The melt passes via the filter or filters into the pipe or pipes, and flows in countercurrent to the mixture situated on the outside of the pipe or pipes, towards a melt discharge. A suspension zone situated in an upper part of the washing column changes into a packed bed of crystals. At the bottom of the washing column, the crystals are washed in countercurrent with their own recirculated melt.

    摘要: In order to remove a constituent from a solution, said solution, a particulate seed material and one or more substances which cause the constituent to be removed to crystallize out on the seed material, are brought together and the seed material having the substance crystallized out thereon is separated. The particles of the seed material have a size between 0.1 and 50 mu m and the mixture of liquid and seed material having substance crystallized out thereon is passed through a membrane filter for microfiltration. The pores of said filter are of such a size that the liquid can penetrate through the membrane, and the seed composition material cannot penetrate through the membrane. The method can be used, inter alia, for softening water, purifying waste water, removing heavy-metal ions, removing anions and preparing ultra-pure products from aqueous solutions or organic mixtures.

The particles of the seed material have a size between 0.1 and 50 νm and the mixture of liquid and seed material having substance crystallized out thereon is passed through a membrane filter for microfiltration. The pores of said filter are of such a size that the liquid can penetrate through the membrane, and the seed composition material cannot penetrate through the membrane. The method can be used, inter alia, for softening water, purifying waste water, removing heavy-metal ions, removing anions and preparing ultra-pure products from aqueous solutions or organic mixtures.

    摘要: The invention relates to a method for preparing furanic compound crystals from sugars comprising the steps of
    - converting sugar or sugar alcohol into a furanic compound in a reaction mixture comprising an organic solvent, thereby obtaining a product mixture comprising a furanic compound dissolved in said organic solvent and water;
    - preferably removing water from the product mixture; and
    - simultaneously crystallizing the furanic compound and the organic solvent by cooling the product mixture, thereby obtaining a slurry comprising solvent crystals and furanic compound crystals; and
    - separating the solvent crystals and the furanic compound crystals.
