Abstract:
     This invention relates to a method for processing the surface of parts by the meltwater of a solvent. Used solvent is cooled and deposited to form an upper layer containing petroleum products, light mecanically foul substance and partial solvent and a lower layer containing solvent, heavy mechanically foul substance and partial petroleum products. The petroleum products are separated from upper layer and the crystal of solvent is molten and merged into lower layer. The solvent is separated from lower layer, used for cleaning parts. The cleaning apparatus includes a system to recover used solvent. The recovering system is connected with the separating systems for upper and lower layers.
