ABSTRACT:
Method and apparatus for removing organic contaminants from contaminated materials including a sealed hopper, a heated vapor stripping conveyor sealed from atmospheric air to vapor strip the contaminants from the material, a sealed conveyor to convey the material in sealed condition from the hopper to the vapor stripping conveyor, a supply of non-oxidative gases at a controlled temperature for introduction into the vapor stripping conveyor, an introduction portal for the non-oxidative gases into the vapor stripping conveyor, an exit for removing the non-oxidative gases from the conveyor and located to cause the non-oxidative gases to cross currently sweep over the material to convey contaminants and moisture stripped from the material out of the vapor stripping conveyor, and a controller for controlling the flow rate and temperature of the non-oxidative gases as they flow through the vapor stripping conveyor and to prevent undue surface drying of the material as the material passes through the vapor stripping conveyor.
