  • Apparatus and method for low temperature thermal stripping of volatile organic compounds from soil and waste materials with non-oxidative co-current gases
    Patent number: 5188041
    Abstract: A method and apparatus for removing volatile organic contaminants from soil and waste materials including transporting and placing the contaminated material into a hopper, the hopper being substantially sealed from the atmosphere to prevent fugitive emissions of the contaminants from escaping into the atmosphere; conveying the material under substantially sealed conditions into a heated vapor stripping conveyor; conveying material under substantially sealed conditions along the vapor stripping conveyor to heat the material and thereby cause moisture in the material and the contaminants to be stripped from the material; streaming non-oxidizing gases at a controlled temperature over the material, in the direction of travel of the material, beginning at a point downstream of and adjacent to the introduction of the material into the vapor stripping conveyor to carry the contaminants and moisture away from the material; and maintaining the rate of flow and temperature of the gases to prevent undue surface drying o
    Type: Grant

  • Apparatus and method for low temperature thermal stripping of volatile organic compounds from soil and waste materials with non-oxidative cross-sweep gases
    Patent number: 5176087
    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
