- the nitrogen gas then rises to the surface in creating an ascending vertical current, thus a calming fluid, in the liquid methane or GN L (-165 0 C) and mixes with the gas sky 2f, the latter then consisting of a mixture of methane and nitrogen.
- the mixture is then recovered at the ceiling 2e of the tank and is sent 56 in a separator 53, for example of the molecular sieve type, where part of the methane is separated and sent by 53i to participate, for example as fuel in the machine propulsion vessel 57.
- the remaining mixture is then redirected by 53 3 to the collector 50 by a compressor 53a which thus ensures the circulation of the mixture for producing the bubble curtain, creating the upward flow of calming fluid within the GN L .
- the isolation valve 52c is opened, then the exchanger 52 is supplied with heat transfer fluid (water vapor), then the metering pump 51a is actuated so as to regasify the liquid nitrogen, then simultaneously the circulation pump 53a is actuated, thus creating the desired bubble curtain within the GN L.
- the injection pump 51a is stopped. and the valve 52c is closed.
- the nitrogen contained in the loop constituted by the gas sky 2f of the tank, the separator 53 and the connecting pipes, remains constant insofar as the separator 53 has a sufficient efficiency and sends only methane as fuel to the main machine 57, either of the steam turbine type or of the piston engine type.
- the gas sent as fuel would then contain nitrogen in addition to methane, which is not a problem for the operation of said main machine 57.
- the concentration in nitrogen and one redone advantageously adding nitrogen continuously, as explained above.
- FIG. 6 shows the device of FIG. 5 equipped with a first nitrogen reliquefaction unit 55a and a second methane reliquefaction unit 55b, which are useful during the shutdown phase of the bubble curtain. Indeed, if one wants to stop the bubble curtain, it continues to circulate the gas mixture, but the separator being provided with a nitrogen outlet 53i and a methane output 53 2 , the nitrogen is advantageously reliquefied in the unit 55a before being returned to the tank 51b, likewise, all or part of the methane is reliquefied in the unit 55b before being returned to the liquid methane storage tank, the residue being advantageously directed towards the main machine 57 to be used as fuel.
- the loop circulation of the mixture of nitrogen and methane generates a significant energy input, due to the circulation compressor 53a, and this results in regasification of a significant portion of liquid methane that must be evacuated because the The vessel gas sky must remain substantially at ambient atmospheric pressure, the vessel and vessel structure not being designed to withstand significant increases in pressure within the tanks. It is thus necessary either to evacuate the gaseous methane, for example by using it as fuel for the main machine, as explained above with reference to FIG. 5, and / or to reliquefy it as explained previously with reference to FIG. It should be noted that nitrogen having a liquefaction temperature substantially equal to -196 ° C at atmospheric pressure, will never be in the liquid phase in liquefied methane at a temperature substantially equal to -163 ° C.
- FIG. 7 shows a preferred version of the invention according to FIG. 5, in which the nitrogen-methane gas mixture leaves the separator 53, then passes through the compressor 53a and passes through a heat exchanger 54 in contact with the nitrogen liquid at -196 ° C.
- the methane is reliquified to GN L, and a mixture of nitrogen gas and methane gas and GN L then descends into the outlet line 54a.
- Said pipe 54a joins the ramp 50 and the nitrogen gas, with possibly traces of methane gas is directed towards the injection rail 50, while the liquid methane, or GN L, is discharged at the bottom of said pipe 54a, by a pipe 54b down the tank 2.
- the hydrostatic pressure created by the compressor 53a is such that the liquid methane contained in the tank can not go up in the pipe 54b, nor reach the gas injection manifold 50.
- the liquefaction of LNG methane in the exchanger 54 absorbs calories and thus boils the liquid nitrogen within the tank 51; the nitrogen gas produced is advantageously directed by a pipe 50a to the pipe 53 3 , preferably just upstream of the compressor 53a.
- Said gaseous nitrogen product can advantageously be reliqued within a unit of type 55a, not shown, and the liquid nitrogen produced is then simply redirected to said reservoir 51.
- the injection ramp 50 is situated in the lower part of the tank 2.
- a plurality of said ramps 50a-50e are advantageously installed at altitudes. variables, for example at 0, 5, 10 and 15m for a tank of 20m height, either near the side walls of the tanks, or towards the axis of the ship, as shown in Figure 4.
- the ramps are thus installed at several levels and are integral with a vertical support 5O 2 connecting the ground 2b of said tank to the ceiling. They pass through the tank 2 from one side to the other, for example parallel to the axis of the vessel and are fed from one end at the vertical walls of gaseous mixture N2 + CH4 under pressure.
- either one is fed to one of the ramps located below the surface 3a of the liquefied gas, or is advantageously supplied several ramps 50c and 50d located at different depths below the surface 3a of said liquefied gas.
- the gas injection being for example separated into two streams at different hydrostatic pressures, the first stream representing for example 70% by volume, is ejected at the collector 50c closest to the surface 3a, the remaining 30% are ejected lower 5Od at a higher hydrostatic pressure, at the collector 5Od below 50c.
- the vertical angles 2d of the tanks are areas where, in case of breaking, there may be significant shocks due to the trihedral shape created by the two vertical walls and the ceiling of the tank.
- gas mixture injections and liquid methane flows created by nozzles associated with ramps 40a-40c as represented in FIG. 4.
- the combination of the two flows makes it possible to create very large fluid movements, and by the presence of gas bubbles, said fluid has a very high compressibility, which can greatly mitigate the effects of possible shocks produced, the bulk of energy of the breaking being absorbed by the compressibility of said bubbles thus created.
- Said surge energy is optionally converted into heat, which, by local vaporization of liquid methane, increases the amount of methane gas circulating in a loop in the device.
- transverse horizontal currents are established for the entire length of the tank by means of said ramps 50, arranged near the vertical longitudinal lateral walls on the one hand, and, on the other hand, horizontal currents located only in the corners of the tank, arranged angularly non-parallel to the longitudinal direction of the tank towards a central vertical axis at mid-length along the longitudinal direction of the tank, that is to say say along a diagonal of a rectangular longitudinal horizontal section.
- a continuous gas curtain along the entire length of the tank.
- the devices have mainly been described as being installed on the walls of the tanks parallel to the axis of the ship.
- devices will also advantageously be disposed on the walls of said tanks, transversely, that is to say perpendicularly to the longitudinal axis XX of the ship, these devices being more particularly effective in the case of resonance phenomena due to pitching or cavally from the ship.
- nozzles are injected, not with nitrogen gas, or a mixture of nitrogen and methane, but directly with liquid nitrogen at -196 ° C. (at normal atmospheric pressure). , stored in specific auxiliary tanks.
- the gas arrives in the liquid state in the diffusion ramps and is ejected in the liquid state within the GN L.
- the latter being at a higher temperature (-165 ° C. at normal atmospheric pressure), warms up then the liquid nitrogen which vaporizes by transferring to GN L its latent heat of vaporization.
- the nitrogen being transferred into the pipes in the liquid state requires pipes of very small diameter compared to the pipes necessary to convey the nitrogen in gaseous form.
- liquid nitrogen is advantageously manufactured continuously from the ambient air, by separation from oxygen and the various rare gases, and then this liquid nitrogen is stored in dedicated reservoirs and the the liquid nitrogen that is sent into the distribution manifold circuit is withdrawn as soon as necessary, to the tanks concerned by the risks of dreaded sloshing phenomena.
- the tanks of GN L are described as being cylindrical with polygonal section, but it remains in the spirit of the invention since the cross section comprises a polygonal portion and a curved portion, as described by for example in the patent WO-2001-30648, it being understood that said curved portion can be assimilated, mathematically and geometrically, to a polygon of finite developed length, comprising an infinity of infinitely small unit length sides.
