- Description
- Westinghouse Savannah River Company (WSRC), managing contractor of the Savannah River Site for the Department of Energy (DOE) near Aiken, South Carolina, is seeking potential vendors to pelletize an inorganic material (monosodium titanate [MST]) for adsorption applications. This specialized task requires vendor knowledge of methods of pelletizing and of handling inorganic solids. R&D for this work is to be minimal as WSRC is seeking application of existing technology to produce pelletized samples for testing and evaluation. Monosodium titanate is a relatively nontoxic inorganic powder available through government owned and publicly available technology. In pellet form its adsorptive capabilities could be exploited in sorption columns for the treatment of millions of gallons of nuclear byproduct supernate at DOE complex sites. MST is produced by the sol-gel hydrolysis of organic titanium chemicals to produce an inorganic sorbent. The powder is inert to highly caustic aqueous feeds. Sorptive properties of the powder are valuable for nuclear waste treatment because of its selectivity for strontium and actinides in neutral to caustic aqueous solutions. There is some evidence that MST might be sensitive to extreme heat and to complete drying; we are thus interested in low-temperature processes that do not attempt to sinter the material. Very importantly, we are interested in processes that do not leave any significant organic materials in the final pellet product. Binding agents shall be highly resistant to dissolution or degradation in caustic solutions. To summarize, the desired pellet product (1) shall contain only trace organic compounds that pose no downstream processing concerns; (2) shall contain MST still retaining good adsorption characteristics; (3) the preferred particle size distribution for the engineered particles is between 250 and 600 micron (30 x 60 mesh) with a mean size near 380 microns; (4) shall be sufficiently porous so that adsorption is still practical; (5) shall tolerate up to 7 molar sodium salts with up to 3 molar free hydroxide; and (6) shall generate few fines, allowing practical sorption column operation. MST is a single-use material, thus elution and strong acid stability is not an issue. Interested companies are expected to provide at least 100g samples of pelletized MST for testing at WSRC. WSRC will provide the MST. Testing will provide comparisons of various materials and results will be available to participants. Favorable results may lead to procurement of pelletized MST for plant use; however, this call is not a procurement and implies no commitment on the part of WSRC or DOE. Any company interested in pursuing this need must respond with a letter of interest (may be submitted by email) no later than August 26, 2003, summarizing the company?s business and technical expertise and motivation for pursuing this opportunity. Qualified companies will be provided with further information on existing MST technology. Company qualifications should include, but not be limited to, compatible product lines, sufficient manufacturing capacity, reasonable schedule for sample provision. Questions and expressions of interest may be addressed to the Point of Contact identified in this Notice: Dr. Charles A. Nash, telephone (803) 725-2615; fax (803) 725-8829; email charles.nash@srs.gov; or address Westinghouse Savannah River Company, Building 773-42A, Room #182, Aiken, SC 29808. This is not a procurement; it is a request for parties interested in future opportunities only.
