A PSA nitrogen generator works by injecting a high pressure nitrogen gas into a tank. The air passes over an adsorbent that inhibits the formation of nitrogen gas. In addition, the adsorbent allows oxygen, carbon dioxide, water molecules, and other impurities to pass through. Then, a recovery tower is used to recover the nitrogen. A PSA nitrogen generator is used for the food industry in a variety of applications, including packaging and the chemical industry. This technology is widely used in wastewater treatment plants.
PSA nitrogen generators can be used in the food industry for many different applications. The gas can be utilized to fill packing materials. Without the gas, food cannot be kept fresh and nutritious. The PSA technology used in these systems can produce the purest nitrogen possible. When installed in a food processing plant, this system can provide inert atmosphere for the transport of perishable products. The onsite nitrogen generators can eliminate the need for external supplies and minimize production bottlenecks.
The PSA nitrogen generator technology is based on the principle of a continuous flow of compressed air through two towers filled with carbon molecular sieve. The compressed air flows through the sieve, adsorbing trace gases and oxygen. The nitrogen is then discharged from the top of the tower, where it re-enters the air. The process cycle is repeated one to two times, which helps keep the food fresher longer. Furthermore, the process also preserves the nutritional value of the food.
