Description

  

  Verfahren zur Erleichterung der Aufspeicherung und des     Versands    von Acetylen,  insbesondere für die Zwecke der autogenen     111etallbearbeitung.       Es ist bekannt, Gase, insbesondere für  Schweiss- und     Schneidzwecke,    in verdichtetem  Zustande aufzuspeichern und zu versenden.  Dieses Verfahren hat insofern Nachteile, als  das tote Gewicht der Füllgefässe gegenüber  dem- Gasinhalt ein sehr hohes ist, so dass die  Lagerung und der Transport solcher Gase  hohe Kosten verursacht. Es ist weiter be  kannt, solche Gase in verflüssigtem Zustande  bei gewöhnlichem Druck aufzuspeichern und  zu versenden.

   In diesem Zustande haben dann  die     Gase    eine tiefe Temperatur, so dass be  sondere wärmeisolierte Gefässe für die Auf  bewahrung dieser Flüssigkeiten erforderlich  sind. Es ist ebenfalls bekannt, dass die hohe  Wärmeübertragung der Flüssigkeiten in sol  chen Gefässen eine lebhafte Verdampfung  herbeiführt, so dass starke     Verdampfungsver-          luste    der verflüssigten Gase bei diesem Ver  fahren nicht zu vermeiden sind.  



  Was insbesondere das in der autogenen  Metallbearbeitung in grossem Umfange be-    nutzte Acetylengas anbelangt, so kann dies  einerseits nicht in verdichtetem     Zustande     aufgespeichert und versandt werden; vielmehr  ist nur seine Aufspeicherung in Absorptions  lösungen, wie beispielsweise Aceton unter  einem geringen Druck zulässig. Anderseits  ist aus Sicherheitsgründen nicht zulässig,  Acetylen in verflüssigtem Zustande bei höhe  rem Druck aufzuspeichern und zu versenden.  Weiter kommt auch die Aufspeicherung und  der Versand dieses Gases     i        r.    verflüssigtem  Zustande bei gewöhnlichem Druck nicht in  Frage, da Acetylen bekanntermassen bei  Atmosphärendruck als Flüssigkeit nicht be  stehen kann.

   Gemäss der vorliegenden     Erf    n  dung wird nun die Aufspeicherung und der  Versand von Acetylen in der Weise erleich  tert, dass es in den festen Zustand überführt  wird, wobei der gebildete Gasschnee zweck  mässig durch Druck verdichtet wird, um eine  geringere V     erdampfung.goberfläche    zu erzielen.  Die Überführung des Acetylens in Schnee      kann dabei durch Abkühlung bis     unterhalb     seines Schmelzpunktes mit den schon be  kannten Mitteln, wie Verdichtung, Entspan  nung, Gegenstromkühlung     usw.    erfolgen.

   Die  Verdichtung des Gasschnees erfolgt zweck  mässig in der Weise, dass in geeigneten Vor  richtungen     Presslinge    geformt werden, die  sich ohne schwere und teure Behälter auf  bewahren und verschicken lassen.



  Process to facilitate the storage and shipping of acetylene, especially for the purposes of oxy-fuel processing. It is known to store gases, in particular for welding and cutting purposes, in a compressed state and to send them. This method has disadvantages insofar as the dead weight of the filling vessels compared to the gas content is very high, so that the storage and transport of such gases cause high costs. It is also known to store and send such gases in a liquefied state at normal pressure.

   In this state, the gases have a low temperature, so that special heat-insulated vessels are required to store these liquids. It is also known that the high heat transfer of the liquids in such vessels causes vigorous evaporation, so that strong evaporation losses of the liquefied gases cannot be avoided in this process.



  As far as the acetylene gas, which is widely used in autogenous metalworking, is concerned, on the one hand, it cannot be stored and sent in a compressed state; rather, it is only permissible to store it in absorption solutions such as acetone under low pressure. On the other hand, for safety reasons, it is not permitted to store and ship acetylene in a liquefied state at higher pressure. Then there is also the storage and dispatch of this gas. liquefied state at ordinary pressure is out of the question, since acetylene is known to not be available as a liquid at atmospheric pressure.

   According to the present invention, the storage and dispatch of acetylene is now facilitated in such a way that it is converted into the solid state, the gas snow formed being expediently compressed by pressure in order to achieve a lower evaporation surface . The acetylene can be converted into snow by cooling it to below its melting point using known means, such as compression, relaxation, countercurrent cooling, etc.

   The gas snow is expediently compressed in such a way that compacts are formed in suitable devices that can be stored and sent without heavy and expensive containers.
