OSTI ID:6886586
This patent describes a method for treating contaminated earth solids which contain volatilizable organic contaminants. It comprises: introducing the contaminated earth solids into a rotary kiln at a gas exit end thereof and removing uncontaminated earth solids form a gas inlet end thereof substantially free of the volatile organic contaminants; introducing liquid or gaseous fuel and combustion air into the gas inlet end of the rotary kiln removing hot kiln exit gases form the gas exit end of the rotary kiln including products of combustion of the liquid or gaseous fuel, volatile organic gases and gas-borne solid particles from the earth solids; recycling a major portion by volume of the hot kiln exit gases to the gas inlet end of the rotary kiln; separating gas-borne solid particles form the remainder of the hot kiln exit gases; collecting the solid particle sand incinerating the remaining hot kiln exit gases to convert volatile organic gases to incinerator products of combustion; discharging the incinerator products of combustion to the atmosphere.
