Industries where cryogenic equipment can be applied

The chemical industry uses, practically, all kinds of technical gases. They serve as raw materials and working medium. This industry is the second largest consumer of technical gases and, as a consequence, of cryogenic equipment. 

• Most of the nitrogen produced is used for the industrial production of ammonia, which is processed into nitric acid, explosives and fertilizers. 
• Chemical industry uses a large number of tanks with oxidation-sensitive internal surfaces, to protect those nitrogen is also used. 
• Nitrogen and argon are used when storing chemical raw materials. 
• Oxygen serves as an oxidant in many chemical reactions that underlie the production of chemical products. 
• Pure gases and mixtures are necessary in this industry also for laboratory research, control and management of chemical reactions, environmental monitoring and detection of explosive concentrations. 

PSKOVTEHGAZ® develops, manufactures, repairs, maintains and modernizes the related equipment: pump units, evaporators, gasifiers, tanks, ramps, etc., and also provides various services and implements integrated engineering projects.

Food industry consumes one tenth of all technical gases, although this sphere of application is rather new. 

• To create an inert environment for the storage, transshipment and packaging of various food products: milk, meat, vegetables and fruits, juices and many other, nitrogen is used allowing to abandon preservatives and increase shelf life preserving the taste of the products. 
• Carbon dioxide is a raw material to produce carbonated beverages, "dry ice" and baking powder. 
• Hydrogen serves to hydrogenate fats (margarine production). 
• The modern food industry uses a large number of refrigeration plants operating on liquid nitrogen.

These industries are also active consumers of various technical gases, and cryogenic equipment is needed to supply and maintain the required parameters. As a rule, medicine uses high purity gases and cryogenic equipment with a high degree of reliability, since most of technical gases applications here are related to support the life of patients. 

• Oxygen and carbon dioxide (in the form of respiratory mixtures) are used to excite the depressed function of breathing. 
• Nitrogen serves as a coolant for transporting organs to the site of transplantation. 
• 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, as well as mineralized drinks have a healing effect. 
• Nitrogen is required to package the medicines, purge and purify pharmaceutical equipment.

The very scale of this industry speaks of its importance as a market for cryogenic equipment. 

• The use of nitrogen in oil and gas production boosted together with coil-tubing development technology. The injection of gaseous nitrogen from a nitrogen plant is the most promising way to reduce the bottomhole pressure which ensures the simplicity and reliability of process control over a wide range. 

In addition, nitrogen is used for: 

• wells capital repairs; 
• natural gas storage and transportation tanks cleaning; 
• blowing, crimping and testing systems and pipelines (before installation, repair, routine inspections); 
• cleaning of containers from explosive fumes; 
• for conservation and emergency work on pipelines; 
• as a protection against explosion and fires (including oil and gas), as well as in fighting fires in mine faces, seams and enclosed spaces. 

Since the middle of the last century, carbon dioxide gas has been injected into oil-bearing reservoirs, but then the application of this technology to increase oil recovery has stopped due to the lack of appropriate equipment. Abroad, an extensive experience in the use of carbon dioxide plants in the field of oil production has been accumulated. In Russia, the interest was only revived in the second decade of the 21st century - due to the depletion of stocks of easily recovered oil. To date, our country also produces the required equipment.

• Carbon dioxide in certain concentrations enhances the growth of agricultural plants, so it is used in greenhouses.
• 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 their mixtures.
• Helium is a unique refrigerant in experimental physics, which makes it possible to use ultra-low temperatures in the study of superconductivity and other properties of materials and media.
• The production of varnishes and paints uses nitrogen to prevent the polymerization of products, to blow technological equipment, and to package products.
• The branch of advertising and entertainment uses neon to create luminous signboards and other promo-constructions, and helium to fill balloons and aerostats of various configurations.
