Abstract (en)

[origin: WO03057377A1] A method for cleaning an article includes the steps of contacting the article with a solvent fluid that includes carbon dioxide, whereby contaminants on the article dissolve in the solvent fluid and displacing the solvent fluid with a displacing fluid, that is other than carbon dioxide. In one aspect, the displacing fluid is at a temperature and pressure sufficient to prevent forming a second phase in the solvent fluid being displaced and at least a portion of the carbon dioxide is recycled to the article. In another aspect, the pressure of the solvent fluid is reduced prior to its displacement with the displacing gas.
