Definitions

  • the present invention relates to the separation of the two phases of a heterogeneous liquid.
  • the proposed invention relates more particularly to the purification of discharge or reinjection water on offshore oil platforms.
  • oil droplets must be extracted in suspension in a main flow of water.
  • This so-called "deoiling" operation must be carried out by a device or a set of devices which must bring together as much as possible four essential qualities:
  • a first quality is the separation efficiency.
  • the purification rate of the water discharged by the device must be maximum. This efficiency is usually measured via the cut-off diameter of the device, that is to say the diameter of the globules beyond which all the petroleum globules are extracted from the water flow. Depending on the values of this cut-off diameter, it will be necessary to carry out the purification in one or two or even three stages in as many separators of different types connected in series.
  • a second quality is the compactness: Given the very high cost of the "on-board ton" on the platform, operators are looking for devices whose weight and volume are as low as possible.
  • the compactness of a device is mainly characterized by the residence time of the mixture in the device: the lower it is, the more the volume and the weight are reduced.
  • a third quality is flexibility in flow: During operation, the water flows to be treated can undergo variations from -50% to -100% of the nominal flow, for example, over times of a few minutes. It is therefore important that the separators can process these fluctuating flow rates without loss of oil removal efficiency. In addition, users are looking for devices with a maximum unit flow so that they can carry out the processing with a minimum number of devices.
  • the fourth quality is a small energy consumption: Energy consumption is not a crucial problem on an operating platform, but the available pressures are often limited to a few bars. It can nevertheless be considered that a device which consumes energy does so in the form of a pressure drop with the appearance of zones of intense hydraulic shear which will split the drops of oil into droplets so small that they will become inseparable. It can therefore be roughly estimated that the lower the pressure drop necessary to ensure the separation, the better the efficiency of the device.
  • More or less similar qualities are desirable for other operations such as the dehydration of crude oil and degassing of liquids, and, more generally in all industrial operations involving either hydrocyclones or centrifuges.
  • document DE-A-1 186 412 (Westfalia 7) describes a separator comprising injection channels which are rotated to apply to the input liquid the speed of rotation which will create the centrifugal force allowing the separation of the components of this liquid.
  • the side wall of the separation chamber of this separator is fixed.
  • the injection channels of this known separator give the inlet liquid, relative to this side wall, a high relative circumferential speed.
  • the object of the present invention is to obtain in a simple manner a improved separation efficiency compared to known separators.
  • the present invention leaves velocity gradients, especially in the vicinity of said axial region of the vortex.
  • the inevitable turbulence in this area has reduced drawbacks there because of the very high value that the centrifugal force takes there.
  • the speed gradients in particular the radial gradient of the circumferential speed.
  • FIG. 1 represents a general view in axial section of a separator according to the invention.
  • FIG. 2 represents a perspective view of the inlet accelerator guides and of the injection conduits, of this same separator with partial cutaway of its side wall.
  • the downstream end of the chamber 2 is occupied by a part 36 which in particular forms the aforementioned outlet diaphragm, the central opening of which constitutes the main outlet opening for the deoiled water. Downstream of this opening, the interior surface of this part is first conical to form a divergent 42, then it becomes cylindrical in its downstream part 46 to form a rotating outlet chamber 44 opening into a fixed outlet chamber. The latter communicates with a fixed main outlet pipe 45 through which the deoiled water is removed from the separator.
  • This downstream part 46 constitutes at the same time a rigid downstream extension of the wall 10 and externally carries two ball bearings 48 which constitute the downstream bearing previously mentioned and are mounted in a fixed hollow downstream body 47. This body forms said fixed outlet chamber from which the main outlet pipe 45 starts.
  • the secondary outlet opening for the oil consists of a fixed tube 28 which passes axially through the downstream body 47 and the outlet diaphragm 36.
  • the inlet duct had a diameter of 30mm.
