Abstract: A method and device for removing organic compounds from soil, solids, sludges and other types of contaminated materials utilizing a non-rotating contactor which can be tightly sealed from air infiltration. Binders such as cement, lime, flyash or kiln dust may be added to the soil prior to treatment so as to aid in the volatilization of the volatile organics and to immobilize the non-volatile constituents in the treated solids. The contaminated materials are fed to a chamber with a movable rake therein and are subjected to temperatures sufficiently high to violatize the organic constituents. The volatilized contaminants are purged with small amounts of air or other non-condensible gas and with superheated steam. The organic constituents can be captured in a vapor phase or they can be condensed and captured in the condensed liquid.
