Apparatus, for separating a lubricant fluid from a viscous fluid wherein the lubricant fluid is used to lubricate a tubular conduit 21 carrying a flow of the viscous fluid, comprises a lubricant separation nozzle 20 for separating a layer of fluid flowing adjacent to an inner surface of the conduit from the rest of the fluid flowing within the conduit. The lubricant separation nozzle may have an annular separation channel 26 configured to open into an aperture of the conduit and be coaxially aligned with the conduit; the opening of the channel 26 may be in a direction opposite to the flow of fluid (see figure 4). |
