The auger's variable speed drive provides feed rate control. Soil inside the TDU floats on top of the molten tin and is heated to 600 degrees Celsius, vaporizing the water and organic material.
Decontaminated soil is removed from the tin bath into a water-filled quench tank.
The water in the quench tank provides a gas seal between the TDU's hydrogen atmosphere and the outside air. A scraper mechanism removes desorbed soil from the quench tank into drums. After desorption from the soil, the organic contaminants are carried from the TDU to Eco Logic's proprietary gas-phase reduction reactor. In the reactor, the organic contaminants undergo gas-phase chemical reduction reactions with hydrogen at elevated temperatures. This reaction converts organic and chlorinated organic contaminants into a hydrocarbon-rich gas product.
