ABSTRACT:
A soil decontamination apparatus is based on a heating operation performed on soil to be contaminated to vaporize and burn off hydrocarbons. The soil is fed into a drum drier at a constant rate which is related to the moisture contents in the soil and the energy available from the burner of the drum drier. Soil particles in the form of dust which become entrained in the hot gases which are used in the decontamination process are removed from the gas stream and are recombined with the base material of the soil in a region of the drum drier which is substantially devoid of gas flow. The substantially calm atmosphere in the region of the drum drier in which the recombination takes place permits the fines to be mixed with the base material without the fines again being carried off by gaseous movement. A soil reconditioning is provided for in an isolated third zone of the drum drier.
