  • Patent number: 8945351
    Abstract: A method of removing organic components from a mixture containing organic and inorganic components which method involves providing an induction heated screw conveyor having an auger and passing the mixture through the induction heated screw conveyor while inductively heating the auger so as to heat the mixture in the induction heated screw conveyor primarily from the center of the induction heated screw conveyor. The mixture is heated to a temperature that is sufficient to cause the organic components in the mixture to separate from the mixture as a vapor. The oxygen concentration in the induction heated screw conveyor is controlled so as to gasify the organic components. The gasified organic components are removed and the remaining inorganic components are collected.
    Type: Grant

  • Patent number: 8945350
    Abstract: A method of separating a high boiling component from a mixture containing organic and/or inorganic boiling components which method involves providing an induction heated screw conveyor having an auger and passing the mixture through the induction heated screw conveyor while inductively heating the auger so as to heat the mixture in the induction heated screw conveyor. The mixture is heated to a temperature that is sufficient to cause the boiling component(s) to separate from the mixture as a vapor and the boiling component is removed from the induction heated screw conveyor.
