  • Reactor for supercritical water oxidation of waste
    Patent number: 5591415
    Abstract: A reactor enclosed in a pressure vessel in a manner that the walls of the pressure vessel are thermally insulated and chemically isolated from the harsh environment of the reaction zone in the reactor. This allows the pressure vessel to handle the high pressures involved, since it is maintained at a reasonably low temperature range. Simultaneously, it allows the reactor to handle the high temperatures involved, since the pressure differentials around it are only minimal.
    Type: Grant
    Filed: June 16, 1994
    Date of Patent: January 7, 1997
    Assignee: RPC Waste Management Services, Inc.
    Inventors: Mark W. Dassel, Donald C. Matter, Donald H. Rennie, Roy N. McBrayer, Jr., James E. Deaton, Fred W. Thompson
  • Kiln control for incinerating waste
    Patent number: 5228398
    Abstract: A method and apparatus for controlling the viscosity of slag contained in a rotary incinerating kiln by detecting the position at which the slag exits the outlet of the kiln, thereby determining changes in the viscosity of the slag. If the viscosity deviates from a predetermined range of values, appropriate additives are supplied to the slag for bringing the viscosity back to within the range of the predetermined values. There is also disclosed a method and apparatus for measuring viscosity as "angular" viscosity.

  • Rotary reactor and lifter assembly
    Patent number: 5040973
    Abstract: A rotary reactor of the type having a cylindrical, horizontally-oriented chamber lined with a refractory for burning materials therein and a plurality of trough-like lifters, extending along the interior surface of the chamber, for lifting and dumping sand in the chamber as the chamber rotates, a long-wearing lifter assemble which minimizes intrusion of contaminants between the lifter and the refractory.
