Definitions

  • the present invention relates to a system and a method for treating gas resulting from the evaporation of a cryogenic liquid and for supplying pressurized gas to a gas engine.
  • the field of the present invention is more particularly the maritime transport of cryogenic liquids and even more particularly of Liquefied Natural Gas (LNG).
  • LNG Liquefied Natural Gas
  • the systems and methods which will be proposed later could also find applications in terrestrial installations.
  • LNG carriers use the natural gas they transport as fuel to ensure their propulsion.
  • engine that run on natural gas.
  • the present invention relates more particularly to those which are supplied with natural gas in a high pressure gaseous phase.
  • gas is pumped out of a liquefied natural gas tank on board the LNG carrier, then is pressurized using a pump before being vaporized in order to be able to power the motor.
  • the document EP-2 746 707 A1 is interested in a natural gas evaporating from liquefied natural gas storage tanks, typically arranged on board a seagoing vessel, which is compressed in a compressor with several compression stages. At least part of the compressed natural gas stream being sent to a liquefier, which typically operates according to a Brayton cycle, in order to be reliquefied. The temperature of the compressed natural gas coming from the final stage is reduced to a value below 0 ° C by passing through a heat exchanger.
  • the first compression stage here functions as a cold compressor, and the resulting cold compressed natural gas is used in the heat exchanger so as to provide the necessary cooling of the flow from the compression stage.
  • the cold compressed natural gas Downstream of its passage through the heat exchanger, the cold compressed natural gas circulates through the remaining stages of the compressor. If desired, part of the compressed natural gas can be used as fuel to supply the engines of the ocean-going vessel. In an alternative embodiment ( ⁇ [0026]), it is planned to cool the compressed gas in the gaseous state. before its liquefaction with partly compressed liquid before it is expanded for use in an engine or turbine.
  • a refrigerant loop with nitrogen in the Brayton cycle implies providing specific equipment for the refrigerant. So, for example, when a nitrogen refrigerant circuit is provided on board a ship (or elsewhere), a nitrogen treatment (purification) unit is necessary to allow its use in the cryogenic field. It is also advisable to provide a specific tank, valves and other devices for regulating the circulation of nitrogen.
  • the object of the present invention is therefore to provide an optimized system making it possible to reliquefy gas which has evaporated and to supply a gas engine under high pressure.
  • the proposed system will make it possible to optimize the quantity of liquid recovered with regard to the portion of gas to be reliquefied.
  • the proposed system could also be used on board a ship such as an LNG carrier.
  • the system will operate without using a refrigerant such as nitrogen or the like to avoid having two separate circuits with fluids of different natures.
  • the proposed solution will also preferably not be more expensive to produce than the solutions of the prior art.
  • the present invention provides a system for treating a gas resulting from the evaporation of a cryogenic liquid and for supplying pressurized gas to a gas engine, said system comprising, on the one hand, from upstream to downstream, a reliquefaction unit with compression means, a first heat exchanger and expansion means, and, on the other hand, a pressurized gas supply line comprising from upstream to downstream a pump for putting liquid under pressure and high pressure vaporization means.
  • the pressurized gas supply line has, upstream of the vaporization means, a bypass for supplying a second heat exchanger between, on the one hand, liquid under pressure from the supply line and , on the other hand, a line of the reliquefaction unit downstream of the first heat exchanger and upstream of the expansion means, characterized in that the gas resulting from the evaporation of a cryogenic liquid, then compressed and cooled is condensed at least partially within the first heat exchanger (17).
  • the proposed solution makes it possible to create a synergy between the reliquefaction of the gas which has evaporated and the production of gas under pressure to supply an engine, for example a MEGI engine. Indeed, on the one hand there are needs to cool the gas and on the other hand there are needs to heat the liquid before vaporizing it.
  • the second proposed exchanger thus makes it possible both to limit the (cooling) requirements of the reliquefaction unit and the (heat) requirements of the high pressure gas supply line.
  • This pressurized liquid must then be relaxed in order to be able to be reintroduced into the reservoirs which are substantially at atmospheric pressure (just a little above to prevent air from entering the interior).
  • part of the condensed gas is vaporized.
  • this gas is subcooled and this makes it possible to limit, during expansion, the portion of condensed gas which revaporates.
  • the bypass can supply a cooling system downstream of the second exchanger. It may for example be a third exchanger mounted in series with and downstream of the second exchanger and / or a heat exchanger mounted in parallel with the second exchanger.
  • a particular variant of a system as described above provides that it further comprises, downstream of the expansion means, a balloon separating the gas phase from the liquid phase in the expanded fluid; that a line conducts the gas phase to a collector to mix it with the gas resulting from the evaporation of the cryogenic liquid, and that the bypass supplies a heat exchanger to cool the gas phase before its introduction into the collector.
  • the system described above is particularly well suited to a reliquefaction unit which uses as coolant the same fluid as the fluid to be liquefied.
  • said unit thus comprises for example, downstream of its compression means, a bypass to a loop comprising second expansion means, and the loop joins the circuit upstream of the compression means after passing through the first heat exchanger. heat in the opposite direction to the fraction of gas in the circuit not diverted by the loop.

  • the second expansion means to include an expansion turbine and for each compression wheel and the expansion turbine are associated with the same mechanical transmission.
  • This third exchanger makes it possible to increase the exchanges and thus to optimize the system.
  • the third heat exchanger can be mounted in parallel with the second heat exchanger and according to another alternative variant embodiment, the third heat exchanger may be mounted in series with the second heat exchanger.
  • the present invention also relates to a ship, in particular an LNG carrier, propelled by a gas engine, characterized in that it comprises a system for treating a gas resulting from the evaporation of a cryogenic liquid and for supplying gas. under pressure from a gas engine as described above.
  • the present invention proposes a method for treating a gas flow resulting from the evaporation of a cryogenic liquid and for supplying a high pressure gas to an engine, said gas flow being first of all compressed. then cooled and condensed at least partially within a first heat exchanger before being expanded, and the supply of gas under high pressure being carried out by pressurizing cryogenic liquid then by vaporizing it, and after its compression, the flow of liquid under pressure being separated into a first part of liquid flow and a second part of liquid flow, and the first part of the liquid flow being used to cool compressed and condensed gas within a second exchanger before expansion of the condensed gas, and the second part of the liquid flow receiving the first part of the liquid flow after the latter has cooled compressed gas, the whole of the liquid flow then being vaporized.
  • the flow of pressurized liquid is also used to cool gas before it is condensed.
  • part of the compressed gas is taken from within the first exchanger to be expanded within an expansion turbine, and that the expanded gas is introduced into the first exchanger. against the current to cool the compressed gas and cause it to condense.
