  • Patent number: 8394288
    Abstract: The invention relates to the use of solid betaine for de-icing and/or preventing slipperiness. The solid betaine comprises at least one non-betaine compound affecting water and/or moisture movement in said solid betaine. The invention further relates to a process for the manufacture of solid betaine. A suspension comprising betaine crystals is prepared from a feed liquid and the betaine crystals are separated and washed. The amount of wash liquid is adjusted in order to leave 0.5 to 10 w-% of at least one non-betaine compound in said solid betaine.
    Type: Grant

  • Patent number: 6821339
    Abstract: The invention relates to a process for the crystallization of substances having a narrow metastable supersaturation zone. In the process the saturation of a solution is gradually increased and the solution is seeded for the crystallization. The seeding is performed at a seeding point which is selected in response to a signal received from said process indicating imminent or initial spontaneous nucleation. The process provides a good crystal yield and a crystalline product having a uniform crystal structure and a narrow crystal size distribution.

  • Patent number: 5980640
    Abstract: The invention relates to a method for recovering a crystallizable organic compound from solutions containing said compound. In accordance with the method, the compound is crystallized substantially by way of nucleation from a solution having high viscosity and high supersaturation in respect of the compound to be recovered, and the formed crystals are recovered.
