Mercury wastes can also be treated. The hot treated solids are cooled and dedusted using the condensed water removed from the feed. An inert carrier gas (nitrogen) transports the volatilized components to a gas treatment train. The gas treatment train removes the entrained particulate solids with a scrubber and then cools the entire gas stream to less than 5 degrees Centigrade (C) (40 degrees Fahrenheit) to condense the volatilized organics. Ninety to ninety-five percent of the carrier gas is reheated to 315 degrees C (600 degrees F) and recycled to the dryer. The remainder of the carrier gas passes through a high-efficiency particulate air (HEPA) filter and a carbon adsorption system before being discharged to the atmosphere. The condensed liquid organic removed from the soil is disposed off site. Page No. 2 of 28 VISITT 4.0 01/26/96 (s3B Vendor Name: RUST INTERNATIONAL, INC. Technology Type: THERMAL DESORPTION (s0B TECHNOLOGY HIGHLIGHTS X*TRAX removes organic contaminants from solids such as soils so that the processed soil can be left on site. The process has been demonstrated effectively on soils contaminated with solvents, chlorinated solvents, fuels, pesticides and PCBs. After removing the water and organic contaminants, the condensed water is added back to the treated soil to cool it and provide a suitable solid for backfilling. X*TRAX has an emission rate approximately 200 times less than that of an incinerator of the same capacity, and in most cases, the X*TRAX operating cost is lower. Also, the X*TRAX treated solids exhibit characteristics similar to uncontaminated soil unlike the ash produced by an incinerator. The transportable Model 200 X*TRAX can process up to 240 tons per day and requires two weeks for on-site setup. Treating 25,000 tons of soil contaminated with 1,000 ppm of organics would produce less than two tank trucks (8,000 gallons) of condensed liquid organic for off-site disposal. The X*TRAX unit has been demonstrated on several mixed wastes (radioactive/RCRA). Radioactive emissions were undetectable, demonstrating excellent air emission control.

Technology Type: THERMAL DESORPTION (s0B TECHNOLOGY LIMITATIONS With the exception of mercury, the process does not reduce heavy metal concentrations. Chemical stabilization reagents can be added to the treated solids before cooling to reduce the leachability of heavy metals when necessary. For economic reasons, the solids content of the feed should be greater than 40 percent. Soils with high levels of natural organic material (peat) should be avoided since the resulting organic acids are water soluble. The feed material must be screened to minus 60 mm (2-3/8 inches) before processing. There is no metals concentration limit for the feed material since volatile metals such as mercury are condensed and any metal containing particulate solids are removed by the HEPA filter before venting to the atmosphere.

Technology Type: THERMAL DESORPTION (s0B OTHER COMMENTS ON TECHNOLOGY As of February 1, 1995, over 110 laboratory-scale and 15 pilot- scale treatability studies have been performed. RUST maintains a dedicated laboratory and staff for performing lab-scale treatability studies which require 6 to 10 weeks from sample receipt to delivery of the test report. The pilot-scale system is available for on site pilot testing. One full-scale Model 200 X*TRAX system has been constructed and has completed operations at the Resolve Superfund site in Massachusetts. The system was used to treat 50,000 tons of PCB contaminated soil. On this project, PCBs were routinely reduced from several thousand ppm to less than 2 ppm. The process air emissions had no detectible PCBs, yielding an equivalent destructive removal efficiency (DRE) of over 99.9999996 percent; no PCBs were destroyed, but rather were recovered as a condensed liquid for disposal. Over 97 percent PCB recovery was demonstrated during a one-month period, confiming the non-destructive basis of the technology. For information on full-scale treatment service please contact RUST at 7250 West College Drive, Palos Heights, Illinois, 60463. Treatability studies are conducted at the Clemson Technical Center in Anderson, South Carolina.

It contains a solids feed screw, externally heated rotary dryer, scrubber and heat exchangers to closely duplicate the pilot- and full-scale systems. A typical initial treatability test is performed at constant residence time and feed rate and two or three treatment temperatures. The high temperature is the maximum practical system temperature, which then produces the maximum removal efficiency. A reduced temperature test is also evaluated to determine the effect of temperature on the removal efficiency of the principle organic hazardous constituents (POHCs). Full-scale costs can be estimated from the lab-scale data. RUST's lab is currently permitted under RCRA, TSCA, and the Atomimc Energy Act (AEA) (radioactive) and can test ANY waste type.

Technology Type: THERMAL DESORPTION (s0B PILOT SCALE INFORMATION Pilot unit processes : The pilot system (400-600 lb/hr) has all the same components as the full-scale Model 200 (8,000-14,000 lb/hr) except for the product solids cooler. The pilot unit is mounted on two trailers. It requires one week for on site setup. Pilot demonstrations have been conducted on RCRA, TSCA, and radioactive waste materials.

Technology Type: THERMAL DESORPTION (s0B FULL SCALE INFORMATION Major unit processes : The full-scale system has a solids feed hopper with a 75 cubic foot capability for material that has been screened to less than 60 mm (2-3/8 inch). An externally fired rotary dryer heats the solids, driving off the water and organic contaminants. The hot solids are conveyed to a product cooler (mixer) where previouly condensed water is used to cool the solids and adjust the moisture content. They are discharged as treated solids. The gas stream (nitrogen) is scrubbed and then chilled to 40 degrees Fahrenheit (F) to remove particulate solids, water vapor, and volatilized organics. A portion of the gas (5-10 percent) is passed through a HEPA filter and a carbon adsorption system prior to venting to the atmosphere. The remainder of the gas passes through an externally fired reheater and is returned to the dryer. The condensed liquid produced as a residual from the chilling process is allowed to phase separate. The aqueous portion is used to cool the product solids. The liquid organic fraction is taken off-site for reuse, disposal or destruction.
