Definitions

  • the liquefaction temperature of natural gas is a cryogenic temperature of -162 °C
  • liquefied natural gas is easily evaporated because it is sensitive to temperature changes.
  • the storage tank storing the liquefied natural gas is insulated.
  • the natural gas is continuously vaporized in the storage tank during the transport of the liquefied natural gas.
  • -Off Gas, BOG occurs.

  • the second compressor 220 is added to the boil-off gas undergoing re-liquefaction without being sent to the gas consumption (C) of the boil-off gas compressed by the first compressor (210). , And then to the heat exchanger (100), the additional compression of the boil-off gas to the second compressor 220, because the required pressure of the X-DF engine or DF engine using a relatively low pressure natural gas as fuel Since it is lower than the pressure required for the reliquefaction efficiency, it is to compensate for the insufficient pressure by the second compressor (220).
  • the second compressor may be oil-free lubrication.
  • the heat exchanger 100 of the present embodiment heats and cools the boil-off gas compressed by the second compressor 220 using the boil-off gas discharged from the storage tank T as a refrigerant.
  • Some or all of the evaporated gas that has undergone the compression of the second compressor 220, the cooling of the heat exchanger 100, and the expansion of the pressure reducing device 300 is reliquefied.
  • the first compressor 210 for supplying the boil-off gas to the gas consumer C is continuously used in the ship operation, while the second compressor 220 used for the liquefaction of the boil-off gas needs to re-liquefy the boil-off gas. Since it is used only when there is, the maintenance cycle is not significantly shortened even when the oil-free lubrication type compressor is applied to the first compressor 210.

Abstract

L'invention concerne un système de reliquéfaction de gaz d'évaporation destiné à un navire. Le système de reliquéfaction de gaz d'évaporation destiné à un navire comprend : un second compresseur destiné à comprimer une partie du gaz d'évaporation ; un échangeur de chaleur destiné à refroidir le gaz d'évaporation comprimé par le second compresseur, en le soumettant à un échange de chaleur avec le reste du gaz d'évaporation non envoyé au second compresseur en tant que fluide réfrigérant ; un premier compresseur destiné à comprimer le gaz d'évaporation faisant office de fluide réfrigérant dans l'échangeur de chaleur ; et un dispositif de décompression destiné à dilater le fluide refroidi par l'échangeur de chaleur.
