Definitions

  • ABSTRACT An apparatus for cooling and liquefying a gaseous mixture by means of a refrigerant fluid formed of a plurality of constituents, comprising a gas compressor, a plurality of tanks for separating gas from liquid and two series of counter current exchangers, said exchangers, for the cooling and liquefaction, being placed at increasing heights so as to provide for a circulation by gravity, along the various exchangers, of the refrigerant liquid injected at the head of each exchanger, and its mixture with the refrigerant gases, said refrigerant gases being liquefied by successive fractions at lower and lower temperatures in a first one of said two series of exchangers and used for cooling and liquefying the gaseous mixture in the other one of said series of exchangers, wherein in at least one series of exchangers at least the exchangers working at the two lowest temperatures are forming
  • the present invention relates to an apparatus for the cooling and liquefaction of gaseous mixtures.
  • the refrigerant fluid utilized is a mixture having a number of constituents which is liquefied by successive fractions in one of the series of exchangers at lower and lower temperatures, and is utilized for cooling and liquefying the gaseous mixture in an exchange column containing the other series of exchangers.
  • This apparatus permits an increase in the flow-rate of refrigerant gas through the exchange column intended for the cooling and liquefaction of the gaseous mixture, in the downward direction of this column, in consequence of the progressive boiling of the refrigerant liquid fractions.
  • the result is that the diameter of the exchange column is larger at the base than at the top, which makes the construction more stable and more rigid, and also more compact.
  • the upper zone of the column, which is the coldest, is the farthest away from the ground, which facilitates its thermal insulation.
  • the present invention has for its object to resolve the problem set by the carrying away of droplets of refrigerent fluid in a simple and effective manner while at the same time ensuring satisfactory thermal insulation of the exchange zone at the lowest temperature.
  • the apparatus for cooling and liquefaction of gaseous mixtures by means of a refrigerant fluid having a number of constituents comprising a gas compressor, a plurality of tanks for the separation of gas and liquid, and two series of counterflow exchangers, the refrigerant fluid being liquefied by successive fractions at lower and lower temperatures in one of the series of exchangers and utilized to cool and liquefy the gaseous mixture in the other series of exchangers, is characterized in that, for at least'one of the series of exchangers, the exchangers working at the two lowest temperatures at least are integrated in a unitary assembly in which the circulation of refrigerant fluid takes place from the top to the bottom, while in the other exchanger or exchangers, the circulation of the refrigerant fluid takes place in the opposite direction.
  • the single FIGURE shows diagrammatically an apparatus for the liquefaction of gaseous mixtures.
  • the liquefaction apparatus shown comprises a compressor 1, in which a refrigerant fluid having a number of constituents is compressed and a condenser 2 in which the compressed fluid is partly condensed and is directed to a tank 3 in which the liquid and vapour phases are separated.
  • the vapour is sent into an exchanger 4 while the condensate L1 is directed on the one hand towards the top of the exchanger 4 and on the other hand towards the central zone of a column 5 constituting a unitary exchange assembly.
  • the liquid L1 is injected into this column in the upward direction by an injection head 6; a valve 7 enables the flow-rate of this liquid to be regulated at the inlet of the column 5, while a valve 8 regulates the flow of liquid directed towards the exchanger 4.
  • the gaseous mixture to be liquefied which passes into the upper portion of the column 5, is cooled in a first exchange zone of this column comprising an exchanger tube 9 through which passes the gaseous mixture.
  • the refrigerant fluid partly condensed in the exchanger 4 is directed towards a tank 10 in which the liquid and vapour phases of this fluid are separated.
  • the vapours issuing from the base of the exchanger 4 are sent to the compressor 1.
  • the liquid L2 contained in the tank 10 is directed on the one hand towards the top of an exchanger 11 in which the vapour coming from the tank 10 is partly condensed and on the other hand, towards the base of the column 5, into which it is injected in the upward direction by an injection head 12 in order to cool still further the gaseous mixture passing through an exchanger tube 13in a second exchange zone.
  • Valves 14 and [5 permit the regulation of the flow of the liquid L2 at the inlet to the column 5 and to the exchanger 11 respectively.
  • the vapours issuing-from of the base of the exchanger 11 are introduced into the top of the exchanger 4 at the same time as the liquid L1.
  • the refrigerant fluid partly condensed in the exchanger 11 is directed towards a tank 16 in which the liquid and vapour phases of this fluid are separated.
  • the liquid L3 contained in the tank 16 is directed, on the one hand towards the top of the exchanger 17 in which the vapour coming from the tank 16 is completely condensed, and on the other hand to the central zone of a column 18 constituting a further exchange unit.
  • the liquid L3 is injected into this column in the downward direction by an injection head 19, the liquid L4 coming from the exchanger 17 being injected at the top of this column, also in the downward direction, by an injection head 20.
  • the gaseous mixture to be liquefled which is sent from the column to the column 18 passes through the exchanger tubes 21, 22, forming in the column 18 the two exchange zones at the lowest temperatures.
  • the liquefied gaseous mixture issuing from the column 18 is directed towards storage tanks, its flow-rate being regulated by a valve 23.
  • the refrigerant fluid in the gaseous state, circulating from the top to the bottom in the column 18, together with the residual refrigerant liquid is conveyed through conduit 24 to the base of the column 5.
  • the flow of gas issuing from the column 18 is then sufficiently large to ensure, in the column 5 the carrying away effect in the upward direction of the droplets of regrigerant liquid which may either come from the column 18 or from the column 5.
  • Valves 25 and 26 permit the regulation of the flow of the refrigerant liquids L3 and L4 respectively at the inlet to the column 18 and a valve 27 regulates the flow-rate of liquid L3 at the inlet of the exchanger 17.
  • vapours issuing from the base of the exchanger 17 are introduced at the same time as the liquid L2 into the top of the exchanger 11.
  • the invention is not limited to the form of construction described, which has been given by way of illustrative example onl
  • the same arrangement may be adopted for the exchangers serving for the liquefaction by successive fractions of the refrigerant fluid.
  • the number of exchangers in the columns 5 and 18 may be variable; the column 5 may be dissociated to form individual separate exchangers in which the circulation of the refrigerant fluid is effected in the upward direction.
  • Apparatus for cooling and liquefying a gaseous mixture by indirect contact thereof with a multicomponent refrigerant fluid comprising in combination a gaseous compressor for compressing said refrigerant fluid,
  • conduit means for connecting said tanks
  • first counter-current cryogenic exchanger unit A in which a first fraction of the refrigerant fluid is circulated, said first exchanger unit A including first means for passing said first fraction of the refrigerant fluid in an upward direction therein and second means for passing said gaseous mixture in a downward direction therein to produce a countercurrent exchange of said first fraction of the refrigerant fluid with said gaseous mixture and to refrigerate said gaseous mixture,
