Among nitrogen adsorption plants of various types, pressure swing adsorption (PSA) plants have found the broadest application world-wide. The system's design is based on the regulation of gas adsorption and adsorbent regeneration by means of changing pressures in two adsorber–adsorbent-containing vessels. This process requires constant temperature, close to ambient. With this process, nitrogen is produced by the plant at the above-atmospheric pressure, while the adsorbent regeneration is accomplished at below-atmospheric pressure. The swing adsorption process in each of the two adsorbers consists of two stages running for a few minutes. At the adsorption stage Oxygen, H2O and CO2 molecules diffuse into the pore structure of the adsorbent whilst the nitrogen molecules are allowed to travel through the adsorber–adsorbent-containing vessel. At the regeneration stage the adsorbed components are released from the adsorbent vented into the atmosphere. The process is then multiply repeated. Why choose PSA nitrogen generator ?High nitrogen purityPSA nitrogen generator plants allow production of high-purity nitrogen from air, which membrane systems are unable to provide – up to 99.9995% nitrogen. This nitrogen purity may also be ensured by cryogenic systems, but they are considerably more complex and justified only by large consumption volumes. The nitrogen generators use CMS (carbon molecular sieve) technology to produce a continuous supply of ultra high purity nitrogen and are available with internal compressors or without.Low operating costsBy substitution of out-of-date air separation plants nitrogen production savings largely exceed 50%.[citation needed]The net cost of nitrogen produced by nitrogen generators is significantly less than the cost of bottled or liquefied nitrogen.Nitrogen Generators Create Less Impact on the EnvironmentGenerating nitrogen gas is a sustainable, environmentally friendly and energy efficient approach to providing pure, clean, dry nitrogen gas. Compared to the energy needed for a cryogenic air separation plant and the energy needed to transport the liquid nitrogen from the plant to the facility, generated nitrogen consumes less energy and creates far fewer greenhouse gases. Why choose YUANDA PSA nitrogen generator ? Technical Features1).

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 being 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 is said to maintain a more stable pressure when heated and cooled[citation needed] and is said[citation needed] to be a larger molecule (109.76 pm) so doesn't permeate the tire as easily as O2[citation needed] (120.74 pm) 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. Petroleum industryIn the petroleum industry, nitrogen is an indispensable component in a number of processes. Most commonly, nitrogen is used to create an inert environment for preventing explosions and for fire safety and to support transportation and transfer of hydrocarbons. Additionally, nitrogen is used for pipeline testing and purging, cleaning technological vessels and cleaning liquefied gas carriers and hydrocarbon storage facilities. Pharmaceutical industryIn pharmaceutical industry, nitrogen finds application in pharmaceuticals packaging, and ensuring against explosion and fire safety in activities where fine dispersed substances are used. Hypoxic air fire prevention systemNitrogen generators are used in hypoxic air fire prevention systems to produce air with a low oxygen content.
