Definitions

  • the present invention relates to a method for producing a gas mixture in a compressed gas container, with at least one component that can be liquefied at ambient temperature and at a pressure below the pressure gas container pressure and with at least one component that is not liquefiable at this pressure and temperature.
  • a pre-gas mixture of a liquefiable component (preferably CO2) and a non-liquefiable component (preferably argon) is first formed with an injector 10, with a mixture proportion CO2 which is greater than the proportion of CO2 in the finished gas mixture.
  • the injector 10 is supplied with gaseous argon at high pressure (p ⁇ 180-220 bar at ambient temperature) from an argon storage container 11 with the interposition of a flow meter 12 with a measuring orifice 12a and a shut-off valve 13 via line 14.
  • gaseous CO2 is removed and sucked in at a low pressure (p ⁇ 40 bar) and the gaseous argon with the gaseous CO2 in a turbulent flow intensely mixed.
  • the pre-gas mixture thus generated flows into one or more compressed gas containers (compressed gas cylinders) 20 provided in parallel, until a quantity of CO2 in the Compressed gas containers 20 is reached, which corresponds to the amount of CO2 that must be contained in the desired gas mixture.
  • the CO2 supply is interrupted and filled via line 14 and the injector 10 or a parallel to the injector 10 secondary line 21 as long as argon in the compressed gas bottles 20 until an amount of argon is reached, which must be in the desired gas mixture.
  • the desired gas mixture composition is determined, for example, by the pressure and temperature compensated flow meters 12 and 15, the output values of which are automatically recorded and, for example, close the shut-off valves 13 and 16 accordingly.
  • the gas mixture composition is determined gravimetrically by one of the bottles (reference bottle) standing on a scale 23.
  • the amount of CO2 is determined by a pressure and temperature compensated flow measurement.
  • the proportion of argon in the mixture is calculated by subtracting the amount of CO2 from the mixture.
  • the mixture production is controlled via a computer and assigned valves etc.
  • the max. permissible filling pressure is constantly monitored, so that this variant is a manometric filling and gravimetric mixing process.
  • the method described above and characterized in the claims is not only for the production of argon / CO2 mixed gases (eg for welding and cutting purposes) with a CO2 content between 2.5 and 20% also for the production of other gas mixtures such as N2 / CO2 Mixtures with up to 30% CO2 content.
  • pre-gas mixture directly to one or more gas bottle (s), but to store it temporarily in a container.
  • the storage container which can also be made portable, can then be used at any location, e.g. the final gas mixture is made at the customer's site.
