ABSTRACT:
An apparatus is disclosed which is capable of efficiently decontaminating soil, and which has several common components with a conventional asphalt production plant. This feature permits a conventional asphalt plant to be retrofitted by the addition of a relatively small number of additional components, so as to permit the apparatus to selectively produce asphalt, or to decontaminate soil. When operated in the configuration for decontainating soil, the soil is initially heated to a temperature above the vaporization temperature but below the autoignition temperature of the contaminants, so as to volatilize the contaminants. The volatilized contaminants are then delivered to an incinerator, wherein the volatilized contaminants are heated to a temperature sufficient to be converted to non-toxic products, such as carbon dioxide and water.
