At Vacuum 2024, which will be held from April 9 to 11, cryogenic equipment manufacturers will be present to introduce their range of products to guests. Participating companies are ready to showcase improved technologies and advanced equipment.

Section in focus: cryogenic equipment
Applications of cryogenic equipment
Cryogenic equipment is widely used in various industries:
 
- Metallurgy
About 17% of technical gases and mixtures are used in metallurgy, on which the use of cryogenic equipment is directly dependent.
  • Oxygen blast accelerates blast furnace processes, allows to obtain pig iron of excellent quality, as well as to turn it into steel.
  • Oxygen-enriched air as well as pure oxygen is necessary for the production of copper, nickel, and lead.
  • Oxygen is also used by metallurgists to reduce exhaust gas and pollutant emissions.
  • Nitrogen is used to protect ferrous and non-ferrous metals during annealing, neutral hardening, cyanidation, hard soldering, powder sintering, and the operation of blast furnace feeders.
  • Argon is necessary in steel production for cleaning, degassing and homogenization. It is also used to create an inert and protective environment for melting, welding and cutting metals and their alloys, such as stainless steel.
- Chemical industry
In the chemical industry most of the technical gases are used, which for the chemical industry are both raw materials and working medium.
  • Most of the nitrogen produced is used for the industrial production of ammonia, which is processed into nitric acid, explosives and fertilizers.
  • The chemical industry uses a large number of vessels with oxidation-sensitive internal surfaces, which also use nitrogen to protect them.
  • Nitrogen and argon are used in the storage of chemical raw materials.
  • Oxygen serves as an oxidizing agent in many chemical reactions underlying the production of chemical products.
  • Pure gases and mixtures are also required by this industry for laboratory research, monitoring and control of chemical reactions, environmental monitoring and detection of explosive concentrations.
- Mechanical and automotive engineering
These industries round out the top three in terms of consumption of technical gases that are required for the application of cryogenic equipment.
  • Oxygen is widely used in metal processing and in welding and cutting of metals in hard-to-reach places.
  • Nitrogen and helium are needed for pressure testing (leak testing) of vessels and pipelines.
  • Argon is an inert medium for welding various special grades of steel and alloys.
  • Carbon dioxide is used in welding to produce welds that are more resistant to mechanical stresses.
  • Like traditional metalworking, laser welding uses oxygen, nitrogen, argon. In new technologies, helium or argon-helium mixture is added to them.
  • In the automotive industry, technical gases are also needed for heat treatment, cutting and welding of metals, and monitoring of environmental emissions.
- Food industry
The food industry accounts for approximately one tenth of the consumption of all industrial gases.
  • Nitrogen is used to create an inert environment for storage, handling and packaging of various food products: dairy, meat, fruits and vegetables, juices and many others, thus eliminating the need for preservatives while extending shelf life and preserving the flavor of products.
  • Carbon dioxide is a raw material for the production of carbonated beverages, "dry ice" and dough leavening agents.
  • Hydrogen is used to hydrogenate fats (margarine production).
  • The modern food industry uses a large number of refrigeration units based on liquid nitrogen.
- Building
The main application of technical gases and cryogenic equipment ̶ deep-sea hydro welding, which requires a dry and stable environment. Inert gases supplied under high pressure are used to displace water from the hydro box. In addition, inert gases are used for the welding process itself.
 
- Medicine and pharmaceuticals
Inert gases are used in medicine and pharmaceuticals to supply and ensure the specified parameters required by cryogenic equipment. Usually, high frequency gases and high reliability cryogenic equipment are used in medicine. This is due to the fact that technetium gases are related to patient life support.
  • Oxygen and carbon dioxide (in the form of breathing mixtures) are used to arouse depressed respiratory function and provide it.
  • Nitrogen serves as a refrigerant for organ transport.
  • Carbon dioxide in solid form ("dry ice") as well as carbon dioxide and other gases are used in cryomedicine - cold treatment, including cryosurgery.
  • Therapeutic baths with dissolved CO2 and mineralized drinks have a therapeutic effect on the body.
  • Nitrogen is required for packaging pharmaceuticals, purging and cleaning pharmaceutical equipment.
  • Space technology and defense
  • These industries utilize the most advanced designs and the widest range of metalworking, so all of the above apply here as well. In addition:
  • Oxygen serves as an oxidizer for rocket fuel.
  • Helium is used in laser technology.
  • Technical gases are required by these industries for superconductor production, acoustic testing, and leak detection.
  • Argon is used as a radiation indicator.
  • Oxygen-helium mixtures are breathed by divers to prevent caisson disease.
- Oil and gas industry
For the oil and gas industry, the use of cryogenic equipment is of high importance. This is associated with coiled tubing technology of well development. Pumping gaseous nitrogen from a nitrogen unit is the most promising way to reduce bottomhole pressure, which provides simplicity and reliability of process regulation within wide limits.
In addition, nitrogen is used:
  • for workover operations;
  • cleaning of natural gas storage and transportation tanks;
  • purging, pressure testing and testing of systems and pipelines (before installation, repair, routine inspections);
  • cleaning of containers from explosive vapors;
  • for conservation and emergency works on pipelines;
  • as protection against explosion and fires (including oil and gas), as well as for fire extinguishing in faces, formations and enclosed spaces.
- Power industry and the Ministry of Emergency Situations
These two industries actively use technical gases (primarily nitrogen) for firefighting and explosion prevention.
 
- Agriculture
The use of inert gases and cryogenic equipment is increasing in greenhouses.
  • The production of nanophotonics, computer devices and other complex devices based on integrated circuits requires the use of ultrapure (so-called "electronic") gases - nitrogen, helium, hydrogen, krypton, xenon and gas mixtures based on them.
  • Helium is a unique refrigerant for experimental physics, allowing the use of ultra-low temperatures in the study of superconductivity and other properties of materials and media.
  • Production of varnishes and paints uses nitrogen to prevent polymerization of products, purge process equipment, and package products.
  • The advertising and entertainment industry uses neon to create luminous signs and other promotional structures; helium to fill balloons and balloons of various configurations.
