Smith, M., A. Groen, J. Hessling, AND E. Alperin. ON-SITE ENGINEERING REPORT FOR THE LOW-TEMPERATURE THERMAL DESORPTION PILOT-SCALE TEST ON CONTAMINATED SOIL. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/R-92/142.
Description:
Performance of the thermal desorption process for removal of organic contaminants, mostly polynuclear aromatic hydrocarbons (PAHs), from soils was evaluated. he Superfund Site soil tested was a fine sandy soil contaminated with creosote. n optimum operating temperature of 550 degrees 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. est results showed that greater than 99% of the PAHs were removed from the soil. he concentration of total PAHs averaged 4629 mg/Kg in the pretreated soils and were below detection In the posttreated soils.
