ABSTRACT:
A method of removing hazardous flammable hydrocarbons from soils comprises introducing the contaminated soil into a rotatable drum open at only one end, introducing flame and hot gases of combustion in the drum while rotating it to substantially expose the soil to the hot gases thereby heating the soil to a temperature sufficient to substantially vaporize all of the contaminant flammable hydrocarbons therein, and continuing to introduce the flame and hot gases whereby the vaporized hydrocarbon is burned in the drum with the exhaust gases of combustion then directed to atmosphere from the open port. The uncontaminated soil is then recovered from the drum.
