The atmospheric air is first compressed to 7 bar pressure in a compressor in a liquid nitrogen factory. To remove the moisture from the air, the cooled compressed air is then run through a moisture separator. After being dried and compressed, the air is run through a bed of carbon molecular sieves to extract the oxygen and nitrogen. After being separated, the nitrogen is permitted to pass through the cryocooler, which lowers the gaseous nitrogen's temperature to liquid at the nitrogen boiling point (77.2 Kelvin). Ultimately, the liquid nitrogen is gathered and stored for various industrial uses in Dewar's vessel. On our website, you may find a large number of suppliers and manufacturers of Liquid Carbon Dioxide.
LN2, or liquid nitrogen, is essential for many industrial uses. Liquid nitrogen plants of the highest calibre are produced by Universal Boschi Plants Inc. The technology and design used in manufacturing are from ING. L. A. Boschi of Italy, which is recognized as one of the pioneers in the development of the cryogenic distillation process. But the majority of people are unaware of the existence of liquid nitrogen plants. It has capacities ranging from 73 litres per hour to 7235 litre per hour, making it capable of producing massive volumes of LN2.
. Liquid nitrogen's low reactivity and extremely low temperature make it useful in a wide range of applications. Among the frequently used applications are:
. Cryotherapy uses it to eradicate irregularities on the skin.
. Blood cryopreservation Biosamples such as sperm, eggs, and animal DNA are preserved using cryopreservation.
. Cattle branding
. Cryosurgery (removing brain tissue that has died)
. When valves are unavailable, workers can work on pipelines or water by quickly freezing them.
. Keeps things safe from oxidation.
. The protection of materials against exposure to oxygen.
. Additional uses include flash-freezing, producing ice cream, producing nitrogen fog, and producing shatterproof flowers.
1. Velocity: Well-made liquid nitrogen filling stations have a phase separator integrated into the design. Nitrogen becomes liquid and gaseous as a result. 100% of the liquid nitrogen flows to the filling stations while the remaining liquid nitrogen remains at the bottom of the phase separator's reservoir. Naturally ascending, the gaseous nitrogen is released through the gas outlet (GN2 outlet). The more nitrogen that fits in a compact place, the less gas there is, because liquid nitrogen has a density that is significantly higher than that of gaseous nitrogen. Therefore, a filling station equipped with a phase separator enables maximum nitrogen to be added to a vessel or dewar relatively quickly.
2. Control of pressure: Dewars come in various varieties. Open dewars (not pressured) and closed pressure dewars are two well-known examples. Pressure dewars are mostly utilized for shipping and storage since they allow for the dewars to hold even more nitrogen. The pressure at which the cryogenic liquid is delivered into the dewar can be adjusted by the user with a liquid nitrogen filling station. This feature adds even more versatility to the program.
3. The filling process is automated: The filling station's intelligent sensors will recognize when a container or dewar is full and will instantly halt the filling process. This automated filling procedure guarantees safety and prevents waste and leaks. Each filling station has a different filling procedure. A temperature sensor is present in an automatic filling station, for instance. When liquid nitrogen is about to pass through a filling station's discharge line or nearly reaches the top of a dewar, this will detect it. At this moment, the filling process automatically ends since the system detects that the dewar is full of liquid nitrogen.
4. Security: Cryogenic liquid handling poses many safety risks. For instance, gaseous nitrogen removes oxygen from the atmosphere, and contact with liquid nitrogen can result in very serious burns. As a result, breathing becomes difficult in an environment with high nitrogen concentrations and inadequate ventilation. A filling station needs to be made as secure as feasible if liquid nitrogen is removed by numerous individuals. This suggests a low probability of leakage and no operational uncertainties or dangers. A reputable fueling station will also have an oxygen detector installed. When too little oxygen is detected in a given location, this detector instantly sounds an alert, which may be a sign of a (liquid) nitrogen leak. Should issues emerge, the filling station's valves that are linked to the sensor will immediately close.
5. Simple to use: A filling station's design combines practicality with safety. Demaco, for instance, has a filling station with a convenient control device that almost anyone can use without any issues. This is highly useful, particularly in areas where a variety of users frequent the filling station.
