ABSTRACT:
A transportable thermal stripping system for removing volatile organic compounds (VOC) from soil is provided. The system includes a vessel in which contaminated soil is placed into contact with a hot gas. The gas is discharged from the vessel and ambient air is introduced into the gas to ensure that the gas remains combustible. A blower circulates the gas to a cyclone separator where fine soil particles and ash are removed from the gas. Next the VOC in the gas are removed by combustion in a burner fired with a supplemental fuel. A portion of the combusted gas is exhausted to atmosphere and the remainder is recirculated to the vessel where the process is repeated.
