  • Process and apparatus for separating substances by crystallization
    Patent number: 5338519
    Abstract: A process is provided for the separation of substances by melt crystallization. The organic mixtures which are difficult to crystallize are heated to a temperature sufficient to obtain a melt with the melt then being moved through a three-dimensional crystallization matrix having a large specific area. The melt is slowly cooled over a temperature range so as to achieve a selective crystallization from the supersaturated melt in the carrier matrix. A deposited crystal phase is thereafter melted and separated from the carrier matrix and removed by centrifugation. The carrier matrix may have a crystallization-promoting microstructure surface and may consist of an openpored foam.
    Type: Grant
    Filed: March 24, 1993
    Date of Patent: August 16, 1994
    Assignee: Sulzer Brothers Limited
    Inventors: Slobodan Jancic, Evangelos Sakellariou
