<p>Disclosed is a method and a system of uniform vapor pathways for soil evaporative desorption. In one embodiment, a batch of contaminated soil is placed inside a treatment compartment through a hopper. The contaminated soil is moved across an inner length of the treatment compartment. As the contaminated soil moves toward a far end of the treatment compartment, planes surrounding the contaminated soil vibrates to facilitate mixing and loosening of the contaminated soil, thereby creating uniform vapor pathways around the surface and within the contaminated soil. A plurality of helical stem auger comprising helical flights may rotate to further mix and loosen the contaminated soil. Heat is applied to the contaminated soil to desorb contaminates within the soil. A vapor extraction line within a core of the hollow stem auger suctions vaporized contaminates out of the treatment compartment and into a reclamation system.</p> |
