November 1992
The ATP system is designed to desorb, collect, and recondense contaminants.
The kiln contains four separate internal thermal zones: preheat, retort,
combustion, and cooling. In the preheat zone, water and volatile organic
compounds are vaporized. Hot solids and heavy hydrocarbons pass through a
proprietary sand seal to the retort zone. After cyclones remove dust from
the gases, they are cooled, and condensed oil and water are separated into
various fractions. Soil passes through a third sand seal to the combustion
zone. Some of the soil is recycled to the retort zone through the second
sand seal, the remainder enters the cooling zone. Soil exiting the cooling
zone is quenched with water and conveyed to a storage pile. The system
treats petroleum hydrocarbons, halogenated hydrocarbons, polynuclear
aromatic hydrocarbons, and volatile metals. The ATP was demonstrated at
two Superfund sites: Wide Beach in New York and Waukegan Harbor in Illinois.
At both sites, 99 percent of the polychlorinated biphenyls (PCB) were
remediated and dioxin and furan stack gas emissions were below site-specific
standards. No leachable products were produced and volatile or
semi-volatile organics were not detected in the treated soils. A PCB
destruction and removal efficiency of 99 percent was achieved at Waukegan.
