Could I know the applications of nitrogen generators?
The PSA nitrogen generator can be used in various fields as below:Food and beverage industriesThe moment food or beverages are produced, or fruits and vegetables harvested, an aging process kicks in until the complete decay of the products. This is caused by bacteria and other organisms. Generators are used to flood the products with N2 that takes out the oxygen and prolongs the product lifetime significantly because these organisms cannot develop. Furthermore, chemical degradation of food caused by oxidation can be eliminated or stopped.Analytical chemistryNitrogen generators are required for various forms of Analytical chemistry such as Liquid chromatography–mass spectrometry and Gas Chromatography where a stable and continuous supply of Nitrogen is necessary.Aircraft & motor vehicle tiresAlthough air is 78% Nitrogen. Most aircraft tires are filled with nitrogen, and there are many tire and automotive shops with nitrogen generators to fill tires, the advantage is that nitrogen in a tank is dry. Often a compressed air tank will have water in it that comes from atmospheric water vapor condensing in the tank after leaving the air compressor. Also, nitrogen maintains a more stable pressure when heated and cooled and is said to be a larger molecule so doesn't permeate the tire as easily as O2 and Argon.Chemical and petrochemical industriesThe primary and very important application of nitrogen in chemical and petrochemical industries is the provision of inert environment aimed at ensuring general industrial safety during cleaning and protection of process vessels. Besides, nitrogen is used for pipelines pressure testing, chemical agents transportation, and regeneration of used catalysts in technological processes.ElectronicsIn electronics, nitrogen serves as an antioxidant in the manufacture of semi-conductors and electric circuits, heat treatment of finished products, as well as in blowing and cleaning.Glass industryIn the glass production, nitrogen proves efficient as a cooling agent for bow oven electrodes, oxidation inhibitor during process procedures, as well as air cooler.MetallurgyThe metal industry generally utilizes nitrogen as a means of protecting ferrous and non-ferrous metals during annealing. Also, nitrogen is helpful in such standard industry processes as neutral tempering, cementing, hard brazing, stress relieving, cyanide hardening, metal-powder sintering and extrusion die cooling.Paint-and-varnish industryPaint and varnish production uses nitrogen for the creation of an inert environment in process vessels to ensure safety, as well as for oxygen displacement during packing in order to prevent polymerization of drying oils.
