B -- SALT RECYCLE SYSTEM FOR MOLTEN SALT TREATMENT OF ORGANIC MIXED WASTES, LLNL MIXED WASTE MANAGEMENT FACILITY DUE 042795 POC John Tennyson, Sr. Subcontract Administrator (510) 423-2383 The University of California, Lawrence Livermore National Laboratory, seeks sources for Salt Recycle System for Molten Salt Treatment of Organic Mixed Wastes, LLNL Mixed Waste Management Facility. The Lawrence Livermore National Laboratory (LLNL), operated by the University of California under contract with the U. S. Department of Energy, is seeking industrial suppliers and/or participants on a salt recycle system to support the Molten Salt Oxidation (MSO) system of the Mixed Waste Management Facility. The technical goal of MSO is to treat mixed waste by destroying the organic constituents while containing the inorganic residues in a molten carbonate salt matrix. The spent salt from MSO goes to the salt recycle subsystem where the remaining carbonate salt will be extracted and reused in MSO, halogen salts are separated for disposal, and inorganic residues are also separated for disposal. The purpose of this announcement is to solicit expressions of interest from companies with expertise in the separation of carbonate salts, chloride salts, and metals, radionuclides, and other mineral residues from such salts. The salt recycle subsystem is a major element of the overall system. LLNL has initiated the Mixed Waste Management Facility (MWMF) Project to demonstrate, at pilot scale, the integrated processes for the treatment of low-level organic mixed waste. Demonstrations, scheduled to begin in late 1997, will provide opportunities for technology transfer to industry and other DOE facilities for many years. Molten Salt Oxidation is a primary treatment process in the initial demonstration. The Molten Salt Oxidation system uses carbonate salts, such as sodium carbonate or a sodium-potassium carbonate eutectic mixture, in the destruction of organic-based mixed wastes. Treatment of halogenated wastes results in formation of halogen salts, such as sodium chloride, in the molten salt bed. Other inorganics in the waste such as silicates, phosphates, toxic metals, and radionuclides will also accumulate as residues in the molten salt bed. The salt recycling system will treat the spent salt by removing the inorganic residues for disposal, separating halogenated salts for disposal, and reclaiming the carbonate salts for reuse. The salt recycling system will be capable of processing salt containing a range of halogen salts (10 to 30 mole percent) at a range of rates (150 to 300 kilograms per hour). Industrial participation is being considered for all phases of the salt recycle system, including process design, equipment design, manufacture, installation and/or activation of salt handling and separation equipment or related subsystems. Respondents may be asked to characterize their system design by running a small amount of known salt through a bench or pilot scale system. Participation shall be in the form of the purchase acquisition of equipment or systems, engineering subcontracts, as a technical advisory role, or a combination of participation roles leading to pilot-scale demonstration. When responding please indicate the area of interest (e.g.: process design, equipment design, fabrication, and/or operation of salt separation equipment, salt handling equipment, etc.) and provide evidence of your demonstrated capability in this area. Neither Lawrence Livermore National Laboratory nor the Department of Energy are under obligation to pay for any material submitted in response to this notice. Responding companies should provide a summary (five-page limit) of their interest area(s) and a contact to receive an information packet(s) from LLNL. Interested firms should respond with a description of qualifications with respect to the foregoing or related fields and specify their small business size standard. Responses are required on or before April 27, 1995. Firms responding to this announcement which fail to provide the required information will not be considered for inclusion into any resulting source list. Facsimile and telephone responses will not be accepted. This notice is to assist the University in determining the potential for competition; no solicitation is currently available. (0094)
