ABSTRACT:
A method of removing hydrocarbons from soils contaminated with various hydrocarbons such as gasoline, diesel fuel, solvents, motor oil and crude oil. The process first screens the soil to remove oversized rocks and debris and to reduce the contaminated soil to uniformly sized particles. The soil particles are moved along a conveyor and first sprayed with an oxidizer diluted with ionized water and then sprayed with only ionized water. The washed particles are then vigorously mixed with their entrained oxidizer and ionized water in an auger mixer for several minutes to oxidize almost all of the remaining hydrocarbons. The washed and hydrocarbon-free soil is then moved by conveyor to a stockpile for storage, testing and drying.
