<p>The method consists in treating the surface of the part with a solvent melt. The spent solution is cooled and settled, so as to form an upper layer containing oil products, light machining dirt and, partially, the solvent and a lower layer containing the solvent, heavy machining dirt and partially, oil products. Then the oil products are separated from the upper layer, whereas the crystals of the solvent are melted and added to the lower layer, which is then separated from the solvent and re-used for cleaning the parts. The installation comprises a system (12) for regenerating the spent solvent connected to a system (20) for separating the components of the upper layer (18) and to a system (21) for separating the components of the lower layer.</p> |
