  • the present invention has tor its object to orercoiue these two disadvantages at one and the sauce time, l or this purpose, ac cording to the present invention, a method ht .lor the separation ot the constituents ot gaseous niirtures hy liquefaction in which the liquid which has heen condensed in the tuhes ol the tube system of the vaporizer of the liquelaction apparatus is dischargedoutat side the said tube system, consists in circulating the said liquid, together with the gases resulting from its vaporization, in com tact with te tube system and down to the end of the said system opposite to that at which the liquid is delivered thereinto by cans
  • the present rocess can lac-modified by circulating if ne be only a part of the ases resulting from the vaporization toget er with the liquid, the more rolatile gases remaining being collected separately.
  • Fi 2 The form of apparatus shown in Fi 2 is exactl the same as that illustra in Fig. 1," with the exception that it is provided with an outlet X for the more volatile gases to rmit their separate collection.
  • a met 10d of va orizin a liquid containing easier liqu able eFements in the liquefaction of gaseous mixtures, such as the liquids rich in methane containing ethylene I and similar impurities in the liquefaction of gaseous mixtures containing hydrogen, which comprises discharging such liquid into an open receptacle situated toward the upper part of a chamber; circulatin it from said receptacle through the cham r in contact with surfaces at a higher temperature, together with the gases resulting from its vaporization; and withdrawing the aforesaid ases, together with any residual liquid, rom the chamber, at substantially the lowest part thereof.
  • a method of vqporizing a liquid containing easier lique able elements in the liquefaction of gaseous mixtures such as the liquids rich in methane contaimng ethylene and similar impurities in the li uefaction of gaseous mixtures containing hy rogen, which comprises discharging such liquid toward the upper part of a chamber; circulating it' in said chamber in contact with surfaces at a higher temperature, together with part of the gases resulting from its vaporization; separately collecting the more volatile part of said uses; and withdrawing the other part oft e gases resulting from the vaporization, to ther with any residual liquid, from the c amber, at substantially the owest part thereof.
  • a method of vaporizing the. li uid which has been condensed and collecte in the liquefaction of complex gaseous mixtures such as those containm hydrogen which comprises discharging suc liquid toward the upper part of a chamber; circulating it in successive layers in said chamber in contact with surfaces at a higher temperature, together with the gases resulting from its vaporization; and withdrawing the aforesaid ases, together with any residual li uid,
  • a method of separating gaseous mixtures containing methane and ethylene and similar impurities which comprises liquefying said gases by bringing the aseous mixture under pressure in heat-exc anging contact with one surface of a substantially vertically extending heat exchanger, collecting the liquefied gases and causes them to flow downwardly and under a lower pressure in heat-exchanging relation with the other surface of said exchanger, and removing the thus-formed vapors together with any unevaporated liquid at the end of said 6.
  • a method of separating gaseous mixtures containin methane and ethylene and similar impurities, which comprises liquefying said gases by bringing the gaseous mixture under pressure in heat-exchanging contact with one surface of a substantially vertical] extending heat exchanger, collecting the iquefied gases and causing them to flow downwardly and under a lower pressure in heat-exchanging relation with the other surface of said exchanger, and removing the thus-formed va rs partly toward the beginning of said ow and partly together with any unevaporated liquid at the end of said flow.
