Technical features and performance advantages of PSA nitrogen generator

PSA pressure swing adsorption Nitrogen Generator adopts the most mature and reliable PSA technology in the world, combined with its unique process flow, optimized pipeline design and advanced filling technology, effectively preventing the peeling failure of carbon molecular sieve CMS, and eliminating the tunnel effect in the adsorption tower. Thus, the performance of carbon molecular sieve is greatly improved. While saving energy consumption, nitrogen with a purity of 97%-99.999% can be produced in one step. If there are special requirements, the purity can reach 99.9995%.

 Nitrogen is the main component of air, accounting for about 79% of nitrogen and 20.9% of oxygen in the air. Nitrogen is a colorless, odorless, non-toxic and non-flammable gas at room temperature and atmospheric pressure, with a boiling point of -195.8℃. Its chemical properties are very stable and it hardly reacts chemically with other substances. In addition to synthetic ammonia, nitrogen is usually used as a protective gas and is widely used in metallurgy, chemical industry, coal, food, medicine, electronics, magnetic materials, transportation, heat treatment, tires, thermal power, aviation and other industries. PSA pressure swing adsorption nitrogen generator uses air as raw material and carbon molecular sieve as adsorbent. It uses the principle of pressure swing adsorption and the selective adsorption of oxygen and nitrogen by carbon molecular sieve to separate nitrogen and oxygen. It is commonly known as Psa Nitrogen generator.

PSA nitrogen generator has advanced unmanned operation: the independently developed oxygen purity analysis controller monitors the purity of nitrogen in real time, and automatically discharges nitrogen that does not meet the purity requirements, thereby eliminating the impact of gas impurity on product quality; reliable PLC control can achieve 24-hour automatic unmanned operation. High-quality nitrogen meets the requirements of various industries: PSA nitrogen generators are usually equipped with high-precision filters to make the dust particles of nitrogen less than 0.01μm and the oil content less than 0.01 ppm. If additional adsorption dryers, sterile filter devices, etc. are equipped, it can also meet the high requirements of special industries such as LCDs, quartz oscillators, food, and medicine.

 PSA nitrogen generator is a kind of on-site nitrogen production, which uses air compressor to provide air as raw material to produce the required pure nitrogen, and the purity can be customized to 95%~99.999%. The advantage of this method is that the cost of nitrogen is low, it only consumes electricity, it is convenient and stable, it is not restricted by traffic, and it is easy to maintain. The disadvantage is that the cost of the equipment needs to be paid once, and the end user needs to perform regular maintenance. You can choose any gas use method according to your needs. In China, due to environmental protection requirements and urban transportation restrictions, about 80% of Chinese factories have switched to using PSA on-site nitrogen generators to provide nitrogen.
