ABSTRACT:
A method and apparatus are provided for remediating contaminated soil having volatilizable organic pollutants in a heated treatment zone, preferably a rotary drum, in gas/solids contact with superheated steam. Treatment gases from the treatment zone are repressurized and reheated for reuse in the treatment zone. Superheated steam is maintained in a closed loop and is maintained at superheated conditions. Vaporized organic pollutants and superheated steam are removed from the closed loop of superheated steam for cooling and condensation to condense water and condense liquid volatilizable organic pollutants and uncondensed organic pollutant vapors.
