ABSTRACT:
A cleaning system and method utilizing sonic whistle agitation to enhance the soil removal and mass transport capacity of the liquid carbon dioxide at low process temperatures. Sonic whistles are within a cleaning chamber, and liquid carbon dioxide is forced out of the sonic whistle jets to ultrasonically emulsify and disperse non-miscible liquids or insoluble solids, such as remove low solubility oils and greases, in the liquid carbon dioxide contained in the cleaning chamber. Cleaning is accomplished at temperatures between -68.degree. F. and 88.degree. F., and the temperature of the liquid carbon dioxide is typically below 32.degree. F.
