Site Technology Capsule: IITRI Radio Frequency Heating Technology

摘要

Radio frequency heating (RFH) technologies use electromagnetic energy in theradio frequency (RF) band to heat soil in situ, thereby potentially enhancing the performance of standard soil vapor extraction (SVE) technologies. Contaminants are removed from in situ soils and transferred to collection or treatment facilities. The Illinois Institute of Technology Research Institute (IITRI) RFH process was evaluated under the U.S. Environmental Protection Agency's (EPA) Superfund Innovative Technology Evaluation (SITE) Program at the site containing various organic contaminants in a heterogeneous soil matrix. The estimated cost to treat 10,152 tons of contaminated soil based on a scale-up of the revised design treatment zone is $619 per ton; the estimated cost to treat 8,640 tons of contaminated soil based on IITRI's theoretical system design is $340 per ton. The IITRI RFH technology was evaluated based on the nine criteria used for decision making in the Superfund feasibility study (FS) process. The evaluation was based on information from the SITE demonstration conducted at Kelly Air Force Base (AFB).
