Helium

Helium inert gas has the following properties: 

  • Has the lowest mass molecule of all gases, except hydrogen.
  • Is an absolute inert gas. It does not form chemical compounds even at high temperatures.
  • Virtually insoluble in molten metal and metal.
  • Through both the smallest openings and pores due to its small atomic diameter.
  • Has the lowest boiling point of all gases in the liquid state of 4.2 K or -269 ° C, which is the coldest liquid of all gases.

Here are some of the properties that make helium an indispensable gas in many applications.

Helium exists in the atmosphere only in very small amounts, only approximately 5 ppmv, making helium extraction from the air very complicated and generally uneconomical. On the other hand, due to the special geological conditions, there are some natural gas sources on earth that show the increased helium content, thus allowing economic exploitation.

GLOBAL LOGISTICS SOLUTIONS

At present, helium is extracted from natural gas in the US, Russia, Algeria, Qatar, Poland and Australia. A large amount of liquid helium is used at the mining site. To transport liquid helium economically, Messer uses special insulated, super-vacuum tanks (TCs) with a maximum capacity of about 40,000 liters. Messer Group has a specialized helium storage system.

After they are filled, the TCs are transported by road and, if necessary, by sea to Messer filling plants. These companies are located in Mitry-Mory (France), Lenzburg (Switzerland), Gumpoldskirchen (Austria), Pancevo (Serbia) in Europe, and in Wujiang and Foshian (both China) in Asia.

FILLING

In our filling plants, we fill liquid helium from the tanks to the TC tanks with smaller super vacuum insulation liquid (mist). The amount of helium is determined by weighing the tank. The unavoidable flash gas during transmission is collected and cleaned with low temperature adsorption when indicated. 

MODERN EQUIPMENTS

To avoid large losses due to evaporation, liquid helium is distributed in specially insulated ultra-vacuum transport tanks. To meet your requirements, we offer a range of 50 to 450 liters of mist depending on the quantity needed.

To withdraw liquid helium, the nozzle must be fitted with a suitable nib. By connecting a helium cylinder, the pressure in the furnace is increased until liquid helium can be drained through the outlet.

On request, specially trained service technicians from Messer can assist with the transition.

APPLICATION

Because of its special properties, helium is also used in a large number of very specialized applications.

Liquid helium is used as a coolant in places where extremely low temperatures (below -200 ° C) are required but conventional refrigerators cannot be used for economic reasons. Often these are the applications that are connected with superconductivity. Of the greatest technical importance are magnetic resonance imaging (MRI) or nuclear magnetic resonance spectroscopy (NMR) and the action of superconducting magnets in particle accelerators.

In addition to its best known use as a lift gas for balloons and balloons, helium is also used in a wide range of engineering applications. Therefore helium is used in many cutting and welding processes as well as in laser technology due to its high thermal conductivity or as a coolant in the manufacture of optical fibers.

Its high diffusion ability also makes it, for example, an ideal carrier gas in gas chromatography or the most widely used detection gas in leak detection.

As well as having many different applications, there are also many different requirements for the quality and distribution of helium gas. The purity of helium ranges from hot air balloon to "6.0", ie 99.9999% purity, and distribution forms from 1 l pressure cans to 200 and 300 bar bottles and is bottled. Packages for trailers provide capacities up to 300 bar to 4000 m3 of helium.

SERVICES AND SUPPORT

Since helium is a rare and valuable product, it must be used as efficiently as possible. Our technical customer service team provides assistance in optimizing helium use and thus minimizing helium loss.
