Definitions

  • the present invention relates to a device for evaporating liquefied gases, such as methane, at low temperature.
  • gases for example methane or natural gas
  • a very low temperature for example - 160 ° C
  • gases for example methane or natural gas
  • This re-vaporization is usually carried out under fairly high pressure, approximately 100 bars, in exchangers of the water-run type, constituted by a bundle of tubes traversed by the product to be evaporated and on the surface of which water is made to run.
  • the bundle tubes are welded to an inlet manifold, where the product is brought under pressure, at low temperature and in a liquid state, and an outlet manifold, where the vaporized product is at about the same pressure. than at the entrance, but at a temperature close to ambient.
  • the materials used to manufacture the vaporizing devices have been aluminum alloys of the A-GS type, containing as alloying elements magnesium and silidum, or of the A-Z5G type containing about 5% of zinc and lower magnesium.
  • the present invention therefore provides a device for evaporating liquified gases, comprising a bundle of aluminum alloy tubes containing magnesium welded at one of their ends to a manifold which receives the liquefied gas, at low temperature and under high pressure, and, at the other end, to an outlet manifold which evacuates the evaporated gas, at a temperature close to ambient and under a pressure close to that of the inlet manifold, this device further comprising means for producing a runoff of water on the outside surface of the tubes.
  • the alloy used contains: magnesium 3.5 to 4.5%, manganese 0.2 to 0.7%, chromium 0.05 to 0.25%, and at most 0.4% silicon , 0.5% iron, 0.10% copper, 0.25% zinc and 0.15% titanium, the remainder being aluminum with the usual impurities, and each tube comprises, on practically all of its length, on the one hand of the internal fins and, on the other hand, two diametrically opposite external fins.
  • the section of a tube comprises a circular central body 1, provided with two diametrically opposite external fins 2,3, each of them having a cross section which decreases as it moves away from the body, without canceling out at the end, and is connected to the body by a fillet.
  • the body has an interior passage 4, presenting eight interior fins 5.
  • the thickness of the wall of the tube between two fins is approximately 1/10 of the diameter of the body while the radial length of a fin is approximately one and a half times this thickness.
  • the tube is a profile obtained by spinning, the alloy used, which is known by the name of A-G4MC, which lends itself well to this technique.
  • each. tube has a length of about 5 m, the outside diameter of the body is 40 mm, the lengths of the outside and inside fins being 20 and 6 mm respectively.
  • the particular shape of the tube required the development of a particular technique to weld these tubes on the manifolds.
  • tubes with a diameter significantly greater than that of the tubes, and of the same metal. They are thick-walled to resist the pressure and the weight of the spray tubes, and have a flat on their upper and lower sides, this flat being of width greater than the outside diameter of the body of the spray tubes.
  • Figure 2 shows in section a tube and a manifold.
  • the tubes are welded to the manifolds with their external fins in the same plane, separated by an interval of the order of a millimeter so as to form a panel.
  • the interval between the tubes is chosen so as to allow for expansion, but without the risk of creating discontinuities due to the film of water flowing on the panel.
  • a distributor of reheating water is arranged around the outlet collector; it consists of an open bottom channel, which lets out a suitable flow of water on both sides of the ring.
  • the panel is extended beyond the last tube by a profile parallel to this tube, having at least one wing situated in the extension of the outer fin of this tube which is directed towards the outside of the panel, this wing being separated from said fin by a distance similar to that which separates the fins from one another inside the panel, approximately 1 mm for example. This avoids a discontinuity in the runoff film at the edge of the last tube.
