Abstract (en)

[origin: EP1038992A1] Solvent treatment of parts involves using closed circuits in which solvent is regenerated by low pressure evaporation and high pressure condensation. Surface treatment of parts is carried out using a solvent or solvent mixture maintained in closed circuits which optionally pass through the treatment chamber and which regenerate the solvent by evaporation at low pressure and condensation at high pressure. An Independent claim is also included for an installation for carrying out the above process. Preferred Features: The low pressure is below atmospheric pressure, especially 0.001-0.95 bars, and the high pressure is above atmospheric pressure, preferably 2-15 (especially 3-8) bars The solvent may be water or an aqueous mixture.
