ABSTRACT:
An apparatus and method are provided for removing volatile organic compounds from soil in order to comply with environmental regulations. The apparatus is comprised of a rotating drum in which the contaminated soil is loaded. The drum contains an auger mechanism which aerates the soil. An air heater generates hot air which is directed to the drum and circulates there-through, causing rapid volatilization of the volatile organic compounds. The volatile organic compounds are then expelled to atmosphere. The removal of volatile organic compounds is conducted in a batch fashion, loading and unloading the drum following each processing cycle. The apparatus is mobile and may be transported to any clean up site.
