A -- LAWRENCE LIVERMORE NATIONAL LABORATORY SEEKS INDUSTRIAL PARTNERS TO COMMERCIALIZE A CATALYTIC REDUCTIVE DEHALOGENATION SYSTEM FOR IN-SITU DESTRUCTION OF CHLORINATED HYDROCARBONS IN GROUNDWATER USING A REACTIVE WELL SOL 00-013 DUE 041100 POC Industrial Partnerships and Commercialization (925) 423-3139 Lawrence Livermore National Laboratory (LLNL), operated by the University of California under contract with the U. S. Department of Energy (DOE), is seeking one or more industrial partners for a catalytic reductive dehalogenation system for in-situ destruction of chlorinated hydrocarbons in groundwater using a reactive well. LLNL, in collaboration with Stanford University, has developed a system for rapidly destroying chlorinated hydrocarbon contaminants that are dissolved in groundwater by catalytic reductive dehalogenation (CRD). CRD utilizes dissolved hydrogen as a reducing agent. In the presence of a palladium-on-alumina catalyst, it chemically transforms compounds such as trichloroethyene (TCE) and tetrachloroethene (PCE) into environmentally-benign ethane without the accumulation of intermediate transformation products such as vinyl chloride. The rapid reduction reactions allow the design of a reactor unit that is compact enough to place within a well bore. Using a dual-screen well configuration, contaminated water may be extracted from one portion of the subsurface, treated by a CRD reactor within the well bore, and then re-injected into another water-bearing zone. This CRD/reactive well configuration may be used to remediate contaminated groundwater in instances where treatment in surface facilities may be otherwise undesirable. At LLNL, a CRD reactor housed within an 8-inch diameter (total depth of 140 ft) dual-screen well has been used to treat groundwater contaminated with TCE, PCE and other chlorinated hydrocarbons for approximately 1 year. In this case, the presence of elevated tritium concentrations in the groundwater precluded conventional treatment methods at the surface while the depth to contaminated groundwater and the aerobic nature of the groundwater geochemistry effectively ruled out other in situ treatment methods (such as passive filter walls or bioremediation). The unit is designed to operate at approximately 3 gallons per minute (gpm), but low permeability of the aquifer materials limits the capacity to approximately 1 gpm. With several minutes of residence time in the catalyst beds within the well bore, removal efficiencies for most of the chlorinated hydrocarbons are maintained at greater than 99%. Companies interested in working with LLNL to commercialize the technology should provide a written Letter of Interest that includes a description of corporate capability relevant to commercialization of the technology and basic corporate information. Respondents are encouraged to provide ancillary documentation such as annual reports, corporate resumes, and technical publications. THIS IS NOT A PROCUREMENT. All Letters of Interest must be received within 60 days of this announcement. Please send Letters of Interest to Eddie Scott, Business Development Specialist, Lawrence Livermore National Laboratory, 7000 East Avenue, Mail Stop L795, Livermore CA 94550-9234, Attention: CBD00-013.
