Through the US Department of Energy's Industrial Waste Program (IWP), work is being conducted to research, develop, and commercialize supercritical fluid cleaning for its potential as a safer technology in a wide range of industrial cleaning operations. Commercialization, which has not proceeded as quickly as expected, is being aided by the Joint Association for the Advancement of Supercritical Technology (JAAST), a research consortium made up of industry, university, and National Laboratory partners. Under the IWP, JAAST is facilitating interaction and communication among those involved in the technology and addressing specific issues slowing its growth and acceptance. As part of the IWP/JAAST effort, Pacific Northwest Laboratory conducted a study to (1) identify and evaluate potential markets for supercritical fluids cleaning, (2) identify and address current perceptions that inhibit the acceptance of the technology into industrial cleaning operations, and (3) develop a plan that will lead to successful deployment and implementation in potential market areas. The approach to gathering the information needed for formulating the plan was to interview several individuals involved in developing, using, or commercializing the technology, specifically, supercritical carbon dioxide (SCCO2), the most commonly used fluid. Several potential markets were identified, including cleaning gyroscope and filling hardware; optical components; instrument bearings; computer disk drive components; medical devices; and fabrics, cloths, and rags. In cases where there are parts with intricate geometries, where water-based cleaning may corrode parts and materials, or where significant time and energy for drying is required, SCCO2 may be an especially attractive alternative. While pursuing these applications, certain barriers still need to be overcome.
