Abstract: An apparatus and process are described for removing contaminants from soil or other substrate materials. A hot pressurized liquid is continuously supplied to a volume of soil or other material contained in a processing vessel. The hot pressurized liquid may be steam, which vaporizes a fraction of the contaminant which is then released through a vapor filter to prevent atmospheric cross-pollution. The remaining contaminant is removed as either a liquid phase or a solid solution phase along with the steam driver. The waste stream and stream driver condense in a collector and are removed from the system. The driver may be recovered for reuse or may be discarded along with the waste stream. The processor may also be used to remove various types of contaminants ranging from light hydrocarbons, chlorinated, solvents, and water soluble organics to heavy oils, paints, heavy metals, and radionucleides.

Abstract: Apparatus for removing residual paint from the inside and outside of an industrial paint spraying outfit includes a drum containing a spray manifold and a hose for connecting the output of the paint pump to the spray manifold. In use, a few gallons of solvent are placed in the drum, and the paint-bearing portions of the outfit are lowered into the drum.
