A METHOD OF REMOVING OIL FROM THE SURFACE OF A WATER/OIL MIXTURE GATHERED IN A RECEIVER IN AN OIL COLLECTING VESSEL AND AN OIL COLLECTING VESSEL

摘要

The invention relates to an oil collecting vessel and to a method of removing oil from the surface of a water/oil mixture gathered in a receiver (10) in the oil collecting vessel. The invention comprises, in the receiver (10), a conical container (12) tapering upwards and open at the top. A rotor (15) is provided in the bottom portion of the container (12) for bringing the water/oil mixture into a rotary motion for creating a conical turbulence in the liquid surface, whereby the oil tends to move towards the centre of the turbulence, wherefrom it can be efficiently removed by pumping. A concentric control means (9) positioned above the rotor (15) prevents the flow of the mixture, and that of oil in particular, from the centre of the turbulence directly downwards.
