  • Precision Cleaning Applications
    CHAPTER 3 PRECISION CLEANING APPLICATIONS 3.1. BACKGROUND Precision cleaning applications are characterised by the extremely fine level of cleanliness required to keep delicate instruments and surfaces operating effectively. Although precision cleaning is needed in a wide variety of industries, several key factors define the applications where precision cleaning is required. These include those applications in which (1) critical cleanliness standards of particulate and/or organic contaminants need to be satisfied, (2) components have sensitive compatibilities, (3) components I $ have physical characteristics such as geometry and porosity which make dewatering crucial in the cleaning process, and (4) components being cleaned are costly. A variety of particulate and nonparticulate contaminants are removed in precision cleaning operations. Particulate contamination includes scrap material created during cutting, drilling, grinding, and buffing of precision parts (e.g., silicon wafers and aluminum storage disk substrates). Nonparticulate contamination includes waxes, finger print oils, and other contaminants. As the term suggests precision cleaning involves cleaning components to extremely strict standards of cleanliness. A good indication of the cleaning ability required for precision cleaning processes is provided in Figure 111-1, which shows the clearance on a computer disk drive relative to the size of various contaminants. The factor that made CFC-113 the precision cleaning solvent of choice is its remarkable chemical stability (manifested directly in its compatibility to structural materials), its low toxicity, and zero flammability.

  • Development and Design of a High Pressure Carbon Dioxide System for the Separation of Hazardous Contaminants from Non-Hazardous Debris*
    DEVELOPMENT AND DESIGN OF A HIGH PRESSURE CARBON DIOXIDE SYSTEM FOR THE SEPARATION OF HAZARDOUS CONTAMINANTS FROM NON-HAZARDOUS DEBRIS* Carol L. J. Adkins and Edward M. Russick <~~ 'f\ «//) - cj^'- - / ^ 61 Sandia National Laboratories, Albuquerque, NM -^ " H. Mike Smith and Ron B. Olson AlliedSignal Inc., Kansas City Division, Kansas City, MO ABSTRACT Under the Department of Energy (DOE)AJnited States Air Force (USAF) Memorandum of Understanding, a system is being designed that will use high pressure carbon dioxide for the separation of oils, greases, and solvents from non-hazardous solid waste. The contaminants are dissolved into the high pressure carbon dioxide and precipitated out upon depressurization. The carbon dioxide solvent can then be recycled for continued use. Excellent extraction capability for common manufacturing oils, greases, and solvents has been measured. It has been observed that extraction performance follows the dilution model if a constant flow system is used. The solvents tested are extremely soluble and have been extracted to 100% under both liquid and mild supercritical carbon dioxide conditions. These data are being used to design a 200 liter extraction system. KEY WORDS: Supercritical, Carbon dioxide, Cleaning 1. INTRODUCTION Large quantities of solid wastes such as rags, kimwipes, swabs, coveralls, gloves, etc., contaminated with oils, greases and hazardous solvents are generated by industry and the government. At present, these materials must be treated as hazardous waste, and the cost of disposal of such large volumes of hazardous materials is high. If the hazardous components (oils, greases and solvents) could be segregated from the much larger bulk of non-hazardous material, then these solid materials could potentially be handled as sanitary waste at significant cost savings.

These parts must be free of organic residue to avoid corrosion in the stockpile. Thermodynamic and kkretic data for selected reactions of Pu metal are evaluated as a basis for assessing the risk of a violent exothermic reaction during the use of SCF C02 on Pu. The need for considering kinetic behavior of a reaction in assessing its thermal risk is demonstrated.

The dry cleaning solution has significant cost, space and resource savings, as well as being easily integrated into painting lines, and can counteract adhesion problems found with powerwash systems. Plastic components have long been cleaned with powerwash systems prior to painting, with components being cleaned with an alkaline medium, followed by several rinsing zones, an adhesive water dryer and a cooling zone. https://www.britishplastics.co.uk/machinery/acp-systems-quattroclean-leads-the-way-for-co2-snow-jet-tech/ 1/6 24.1.2019 ACP Systems quattroClean leads the way for CO2 snow jet technology - British Plastics and Rubber Cleaning not only takes up a lot of production space, but also consumes large quantities of resources. In contrast to wet-chemical processes, the quattroClean system from ACP Systems uses a dry cleaning technology with a liquid carbon dioxide cleaning medium, which has an almost indefinite shelf life. It is also environmentally neutral, generated as a by-product in the chemical industry, as well as when energy is generated from biogas. The non-combustible, non-corrosive and non-toxic carbon dioxide is fed through the non-wearing two-component ring nozzle and expands on exiting to form fine CO2 snow crystals.

  • SUPERCRITICAL FLUID SPRAY APPLICATION PROCESS for ADHESIVES and PRIMERS SERDP Project PP-1118 Marc D. Donohue Principal Investi
    SUPERCRITICAL FLUID SPRAY APPLICATION PROCESS FOR ADHESIVES AND PRIMERS SERDP Project PP-1118 Marc D. Donohue Principal Investigator Johns Hopkins University March 2003 Preface Project Background In this project, we reformulated various solvent borne, high volatile organic compound (VOC) adhesives and adhesive primers, as cited in SERDP’s Statement of Need, for application by a supercritical carbon dioxide spray process. Over the last several years, a new spray application process has been developed for polymeric based paints and other coatings that can reduce solvent VOC emissions up to 80%. This process was conceived by the principal investigator of this project and has been commercialized by the Dow Chemical Company. This unique process (known as the UNICARBâ process) is based on the use of supercritical carbon dioxide as a replacement for organic solvents in multi-component spray coating formulations. By adapting this process to adhesives and adhesive primer applications, stringent compliance standards can be achieved respective to environmental, toxicological, materials compatibility, and, physical property performance characteristics as outlined in the original proposal and Statement of Need. Furthermore, by employing this process to apply adhesives that are presently used in the military, the costs incurred for developing and testing new (different) low/no-VOC, non-structural adhesives will be negated. To accomplish this task, a systematic program was implemented aimed at understanding the thermodynamic and rheological properties of adhesive-solvent-carbon dioxide mixtures for each type of adhesive and primer. Additionally, optimal conditions of temperature, pressure, and polymer/solvent ratio were determined for each adhesive and primer type such that proper atomization and film formation was achieved while simultaneously VOC emissions are minimized.
