    摘要: A process for re-refining used lubricating oil (ULO) having thermally unstable additives. ULO is heated by mixing with superheated lubricant boiling range hydrocarbons recovered and recycled from the process. The mixture of ULO feed and superheated hydrocarbons is charged to a vacuum column, producing an overhead vapor free of unstable additives and a residual fraction, containing additives. The overhead vapor is condensed to produce an overhead liquid of lubricant boiling range hydrocarbons, a portion of which is recovered as a product and a portion of which is recycled. The overhead liquid free of unstable additives, may be superheated without fouling to produce superheated fluid which can heat the ULO feed sufficiently to permit fractionation. Superheating may occur in a fired heater or preferably in a heat exchanger to prevent high temperatures and cracking of recycled liquid. Mixing of superheated fluid and ULO feed may occur in a pipe in fully developed turbulent flow, and preferably via an inline mixer. Energy efficiency is improved by heat exchanging ULO feed with product streams.

    摘要: A vortex flowmeter is provided with a vortex-inducing bluff body in the form of a first, upstream, cylinder having a semi-circular or semi-ellipsoidal front surface and a planar rear surface, and a second, downstream, cylinder having a planar front surface and a planar or concave rear surface. The rear surface of the upstream cylinder is parallel to the front surface of the downstream cylinder, and separated from it by a gap whose width is preferably about 25% of the diameter of the upstream cylinder.

    摘要: A device for recovering oil floating on the surface of water comprising a framework (50) and a number of discs (51) rotatably mounted thereon. The framework is supported on floats (58,59) with the discs partly immersed in the water, and each disc is associated with a scraper (57) and chute (54) so that oil removed from the disc is deposited into a collection tray (52) from which it can be removed via line (53). Each disc (51) carries at least one axially directed concentric ring (4,5) which presents an inwardly directed surface (7,8). Each disc may carry a plurality of rings of the same or different axial depths.
