Description

Verfahren zum Speichern von flüssigem Sauerstoff Es ist bekannt, daß der in Luftzerlegungsanlagen erzeugte flüssige Sauerstoff neben Wasser- und Kohlensäureeis noch Acetylen und andere Kohlenwasserstoffe, u. a. auch Schmierölreste, enthält, die mit der zerlegten Luft in <leti Lufttrenner gelangen, und claß sich diese Kohlenwasserstoffe beim Eindampfen des flüssigen Sauerstoffs auch im flüssigen Rest anreichern, was dann zu Explosionen von mitunter .großer Zerstörungswirkung führen kann. Aus diesem Grunde sind Behälter und. Vergaser, in die der flüssige Sauerstoff aus dem Lufttrenner abgefüllt wird, gefährdet. besonders wenn in einem rehälter große Mengen von Sauerstoff eingedampft werden, ohne daß der Behälter kurzfristig erwärmt und -dabei gereinigt wird.Method for storing liquid oxygen It is known that the liquid oxygen produced in air separation plants in addition to water and carbonic acid ice nor acetylene and other hydrocarbons, including also contains lubricating oil residues, which get into <leti air separators with the split air, and these are removed Hydrocarbons in the evaporation of the liquid oxygen also in the liquid residue enrich, which then lead to explosions, sometimes with a great destructive effect can. For this reason, containers and. Carburetor, in which the liquid oxygen is filled from the air separator. especially when in a deer container Large amounts of oxygen can be evaporated without leaving the container briefly heated and cleaned in the process.

Man hat bisher diese Gefahr in Kauf nehmen müssen oder hat die langfristige Lagerung von flüssigem Sauerstoff, mit der ein langsames Eindampfen verbunden ist, unterlassen.Up until now you have had to accept this risk, or you have the long-term one Storage of liquid oxygen, which is associated with slow evaporation, fail.

Erfindungsgemäß wird der flüssige Sauerstoff auf dem Wege vom Lufttrenner zum Speicherbehälter oder Vergaser über ein nicht brennbares Adsorptionsmittel, wie Silicagel, geführt. Das Adsorptionsmittel adsorbiert die in flüssigem Sauerstoff gelösten Kohlenwassenstoffe und hält auch andere suspendierte Verunreinigungen zurück. Vorteilhaft ist es, dem Adsorptionsmittel ein Filter, beispielsweise aus keramischem Material, vorzuschalten, welches die groben, nicht gelösten Verunreinigungen abfängt. Der flüssige Sauerstoff wird auf die beschriebene Weise gereinigt. Seine Lagerung im Speicher ist dann gefahrlos, weil Eindampfrückstände von Kohlen-wasserstoffen nicht mehr entstehen. ' Das Adsorptionsmittel verliert mit fortschreitender Beladung mit den VerunreitkiguWn des Sauerstoffs an Reinigungskraft. Es wird'dann durch Anwärmen auf etwa 8o'- C und Überleiten von `warmem Stickstoff von den aufgenommenen Verunreinigungen befreit. Es ist dann wieder neu heladungsfähig. Zweckmäßig baut man in die Leitung zwischen Lufttrenner und Sauerstoffspeicher zwei parallel geschaltete Adsorber ein, von denen einer in Betrieb ist, während der andere durch Anwärmen regeneriert wird.According to the invention, the liquid oxygen is supplied by the air separator to the storage tank or gasifier via a non-flammable adsorbent, like silica gel. The adsorbent adsorbs the liquid oxygen dissolved hydrocarbons and also holds back other suspended impurities. Advantageous is to give the adsorbent a filter, for example made of ceramic material, which removes the coarse, undissolved impurities intercepts. The liquid oxygen is purified in the manner described. His Storage in the storage facility is then safe, because evaporation residues of hydrocarbons no longer arise. 'The adsorbent loses as the loading progresses with the pollution of the oxygen in cleaning power. It is then by warming up to about 8o'-C and passing over `warm nitrogen from the absorbed impurities freed. It can then be recharged again. It is expedient to build into the line Two adsorbers connected in parallel are inserted between the air separator and the oxygen storage tank, one of which is in operation while the other is regenerated by heating.
