  • Hot Gas Decontamination

    Introduction: The process involves raising the temperature of the contaminated equipment or material to 260 °C (500 °F) for a specified period of time. The gas effluent from the material is treated in an afterburner system to destroy all volatilized contaminants. The method eliminates a waste that currently is stockpiled and requires disposal as a hazardous material. This method will permit ...
