Performance of the thermal desorption process for removal of organic contaminants, mostly polynuclear aromatic hydrocarbons (PAHs), from soils was evaluated. The Superfund Site soil tested was a fine sandy soil contaminated with creosote. An optimum operating temperature of 550 C and an optimum operating residence time of 10 min, determined from bench studies, were used in the pilot-scale desorber. Contaminants removed from the soil were captured or destroyed in the associated air pollution control equipment. Test results showed that greater than 99% of the PAHs were removed from the soil. The concentration of total PAHs averaged 4629 mg/Kg in the pretreated soils and were below detection in the posttreated soils.
