ABSTRACT:
A process is described for removing oil from oily metal chips. Hot pressurized liquid water is continuously passed over a bed of the chips contained in a pressurized vessel. In one embodiment, the water is expanded over the chips to partially vaporize the liquid water and greatly reduce the density of the flowing stream. The density reduction increases the velocity of the stream flowing over the chips and increases the frictional cleaning effect of said stream. A water-oil mixture is continuously removed from the vessel.
