This invention relates statements;
the separation,- fbyithej liquefaction method, of the constituents of certain complexgaseous mixtures, such for exam le as water 5 gas, ordinary lighting gas, coeoven and analogous uses; Y
One of t e usualinethodsogt treatin these ases consists in condensing; certain 0 their" quefiable constituents by passing them n into a single bath of these same constituents, which have been previously condensed, such hath boiling under a lower ressure than the gaseous mixture treated. 1 however this mixture has. not previously been suitably in freed from its more condensable constituents, or it this elimination has not been complete, these more liquefiable constituents are condensed at the same time as those which liquety alterwards, and if their vapor tenan sion is not eullicient they will accumulate in the hath previously referred to, and will thus progrcssirely raise its boiling temperature to an entent which may he detrimental to the elficiency oil the condensation.
Furthermore the use oi such a large bath at considerable height presents with certain liquids, and in particular with methane which truths ahundantly when hoiling, the dieadrantage o'l trequently leading to over an tlowing which is preyudicial to the working, 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 of a series of suitable haffles, and then withdrawing from the vaporizer at the end at the tube system the whole of the aforesaid gases together with any residual liquid. lit The said ases and. residual liquid, if any,
may be de ivered either to another compartthus eventually vcordanc'e with t "meat where the same operation recommences withothcr and more liquefiable constituents,
or to the temperature exchangers where the more; condensable constituents (which are eliminated without having to the means adopted in acv e invention, to accumulate) are; again vaporized without having impalre the working of the process. The elinnnation of these products is furthermore facilitated if the exchanger to which they are delivered is such that their circulation :herein takes place from the top to the bot- The present process moreover renders unnecessary the use of a bath containing a con siderahle quantity of liquid which is subject to the disadvanta e of overflowing, as previously mentionecfi The process is independent of the direction' of the circulation of the gases treated in the tube system,
Further if desired 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.
In order that the said invention may he beenable, owi
clearly understoodand readily carriedinto effect, the mine will now be described more tally with reference to the accompanying drawing, which illustrates diagrammatically and by we of example, in Figure l, an apparatus "or carrying out the process for the treatment of ordinary lighting or coke oven gas for the pur ose of extracting the hydrogen contained t erein. Pie 2 is a tragmental view of an apparatus tor carrying out the modified process just described,
he compressed gas to be treated, previous 1 cooled, is admitted through the inlet 0 to the lower part of the tube system F which constitutes, for example, the lower part of the apparatus proper for the liquefaction and extraction of the hydrogen, A large part of the methane of the is condensed in the interior of the nest of tubes F, and the liquid methane collected in the reservoir A, whence it is delivered through the tube T outside the nest of tubes 1} into the com- Hit partment B. The li uid which ascends through'the tube T is rst of all discharged into a collector C, thereby forming a reserve of liquid, which by overflowing falls from the collector C u on the successive lates P. The gases forme by the boiling o the methane cannot escape at the upper part of the com 'artment B and are forced to escape who with maybe a certain quantity of liquid: through the outlet D at the lower part of the compartment B.
These gases, which may be mixed with liquids, are sent to the temperature exchangers; if these latter are such that the circulation of the mixture takes place from the top to the bottom, the elimination of the impurlties contained therein is facilitated.
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.
