Abstract
Treatment apparatus and a process for thermal desorption of hydrocarbon contaminants from excavated soil provides efficient contaminant removal by handling the soil in a thermally conductive treatment vessel that fits within an insulated treatment chamber. The soil is treated in this chamber with fresh air that is dried and electrically heated prior to contacting the treatment vessel. The dry air passes through the soil and the air mixed with contaminants is withdrawn from the chamber through piping in the treatment vessel. Excavating the soil directly into the treatment vessel allows the treated soil to be returned to the final disposition site in the same vessel, minimizing soil handling.
