Convenience
With out psa nitrogen generator you have no more loss of gas supply during analysis as nitrogen can be delivered on-demand,no need to manage gas stock inventory with a psa nitrogen gas generator or reorder bulk supply.
Consistency & reliability
A psa nitrogen generator is a constant gas supply and is delivered at a stable purity, so no risks of pipeline contamination that could hamper analysis results & workflow productivity.
Low operating costs
Substituting out-of-date air separation plants can lead to nitrogen production savings in excess of 50%,the net cost of on-site psa nitrogen gas generation is significantly less than the costs of bottled or liquefied nitrogen bulk supply purchase.
Nitrogen generators are less damaging to the environment
On-site psa nitrogen gas generation is a sustainable and energy efficient approach to providing pure, clean, dry nitrogen gas. Compared to the energy required by cryogenic air separation plants, as well as transporting liquid nitrogen from the plant to a facility, nitrogen generators consume far less energy and lead to a significant reduction in carbon footprint.
On site liquid nitrogen generator
The main function of on site liquid nitrogen generator is to ensure reliable and persistent liquid nitrogen supply, especially in areas that need a large amount of liquid nitrogen, such as artificial insemination stations. In the process of artificial insemination, a large number of sperm samples need to be stored efficiently to ensure that high -quality products can be provided at any time.
Small liquid nitrogen generator
Cryogenic air separation equipment can be used in many fields such as chemical industry, new energy, metallurgy, etc., and is required for industrial production that requires a large amount of high-purity nitrogen. The cryogenic air separation unit uses low-temperature condensation to convert air into a liquid state. Because different gases have different evaporation temperatures, they can be separated and purified from the air, and a large amount of high-purity nitrogen, oxygen and other gases required by industry can be obtained.
Industrial liquid nitrogen generator
The heat balance of the cryogenic air separation plant is accomplished through the refrigeration system and the heat exchange system. With the development of technology, the current heat exchangers mainly use aluminum plate-fin heat exchangers.
Cryogenic nitrogen generator
The air positive flow expansion process is generally applicable to occasions where the pressure level of the nitrogen product is not very high the raw air is divided into two streams after dedusting, compression, pre-cooling and purification: One stream enters the main heat exchanger, is cooled to a certain temperature by the returned dirty nitrogen, and then is pumped out from the middle of the main heat exchanger for expansion. The bottom of the nitrogen tower participates in rectification; another stream of air is cooled to the saturation temperature in the main heat exchanger, and is directly throttled into the nitrogen tower to participate in rectification.
Air separation cold box
Air separation cold box is a complete package containing a brazed aluminum heat exchanger within a carbon steel enclosure with structural support, insulated enclosure and internal equipment protection. Insulation of the heat exchanger and piping assemblies can be easily accomplished with perlite insulation, and the interior of the cold box will be pressurized and purged with dry nitrogen.
Cryogenic equipment
Cryogenic equipment is widely used in the fields of gas separation and liquefaction. With advanced low -temperature technology, efficient gas purification and separation are achieved to meet various industrial and scientific research needs. Cryogenic equipment has liquefied and extracted the air components such as nitrogen, oxygen, and crickets by cooling the air to extremely low temperature.
Cryogenic nitrogen plant is an industrial system that produces nitrogen by liquefaction of atmospheric air in the air separation unit (asu). Nitrogen is one of the most important industrial gases comprising around 78% of earth’s atmosphere by mass. In fact, it is known as the largest industrial gas because of its extensive industrial applications. This gas is known for its inert properties because of which it finds applications in running manufacturing operations. It is used in manufacturing of electronic, brewing beer and food packaging. There are many other important applications of the inert gas. Industries meet their nitrogen requirements either through subscribing nitrogen cylinders or by installing onsite liquid nitrogen plant.
Nitrogen is produced in the cryogenic nitrogen plant by taking atmospheric air. When the atmospheric air is taken inside the air separation unit (asu), it is compressed in the compressor. Then, it is moved through the cleanup system where impurities like hydrocarbons, moisture and carbon dioxide are eliminated. Here, the air is directed into the heat exchangers to liquefy it at cryogenic temperatures. At this stage, the air is put through high pressure distillation column where nitrogen is physically separated from oxygen and other gases. Nitrogen so formed is collected and put into a low pressure distillation column where it is distilled till it meets commercial specifications.
In order to prevent oxygen deficiency from occurring, areas where nitrogen is used or stored require sufficient ventilation. These ventilation requirements are typically established by regulatory bodies, industry organizations, and relevant authorities. These could include but are not limited to, occupational safety and health administration (osha), national fire protection association (nfpa), and american national standards institute (ansi) to name a few.
The ventilation requirement consensus typically states that at least four to six changes of fresh air are needed per hour and should be provided. This does depend however, on room size, the quantity of nitrogen being used and the presence of an oxygen gas detection monitoring system.
