Definitions

  • a system for filling and draining a storage tank with liquified gas and/or for cooling and heating stored liquified gas includes a heat exchanger having a chamber with two nests of tubes, one for circulating cooling or heating medium and the other for circulating liquified gas.
  • the other nest of tubes is connected by conduit means to a storage tank while the chamber itself is connected by further conduit means both with the first conduit means and also through a compressor and pump with the storage tank.
  • the invention relates to an arrangement for filling and draining storage tanks with liquified gas and/or for cooling or heating the stored liquified gas.
  • the arrangement is particularly useful for tanks on ships.
  • a liquified gas plant which contains heat exchangers of different types in addition to the liquified gas pumps and compressors.
  • acondenser cooled by water or sea water is inter alia necessary in order to condense, in a reliquefaction circuit, vapours which are formed during the charging of liquified tanks or as a result of warming of the liquified gas.
  • Vaporizers are necessary in order to be able to produce gas from the liquid, which gas is delivered with the aid of a compressor as a pressurecushioning'means to the tank to be discharged. This produces a sufficiently large initial pressure for'the discharge pumps. Furthermore, the necessity also arises from time to time for the liquid to be heated before loading or unloading, for which purpose a heat exchanger is likewise necessary.
  • the liquified gas plant thus requires three heat exchangers, in order to be able to accommodate all requirements for loading and unloading the storage tanksand also for cooling or heating of the loaded material. Since each such apparatus has to be provided in duplicate for safety reasons, the number of heat exchangers which must be present is thus doubled.
  • two nests of tubes which are independent of one another areassociated with a chamber of the heat exchanger, one of the nests of tubes being on top and arranged such that it can be charged with liquified gas and the other nest of tubes being at the bottom and arranged to be charged with water, for example, fresh water or sea water.

No longer is it necessary to have three different heat exchangers, or six, because of safety regulations, but a single or pair of heat exchangers is sufficient for meeting all contingencies.
  • the liquid level in the heat exchanger chamber can be regulated in relation to the nests of tubes by means of a level regulator known in the art. In some instances a level at which the two nests of tubes areimmersed in the liquid will be required while in other instances the height will be adjusted between the two nests of tubes.
