  • Method and apparatus for treating waste containing organic contaminants
    Patent number: 4925389
    Abstract: A system including a method and apparatus for treating waste containing organic contaminants which includes a direct fired, countercurrent, rotary kiln providing a soaking zone having an oxidizing atmosphere through which the materials being treated are passed after the unwanted organics are removed, and a secondary combustion chamber for oxidizing gases containing vaporized or pyrolyzed organics in which the organics are burned and are subjected to high temperatures for a holding time sufficient to effect destruction of the organic contaminants. The system includes means to minimize off-gas so as to make possible a reduction in size of the equipment employed.
    Type: Grant
    Filed: January 23, 1989
    Date of Patent: May 15, 1990
    Assignee: International Technology Corporation
    Inventors: Steven G. DeCicco, Sung K. Lee, Rudy G. Novak, William E. Wass, Kai K. Mak
