PSA Nitrogen Generator Manufacturer from China

Release Date: 2023-11-15

Nitrogen generator refers to equipment that uses air as raw material and uses physical methods to separate oxygen and nitrogen in it to obtain nitrogen. According to different acquisition methods, it can be divided into cryogenic air separation method, molecular sieve air separation method (PSA) and membrane air separation method. Nitrogen generators used in industry can be divided into the above three types. The development of nitrogen generators has generally gone through a development process of catalytic combustion → carbon molecular sieve adsorption → fiber membrane separation. Its rise is relatively short, but its development momentum is great.

The development of nitrogen generator manufacturers in China began in the 1970s. The more representative RICH Company was founded in 1979. It mainly uses the principle of pressure swing adsorption and uses molecular sieves as the adsorbent to produce nitrogen. With the continuous development of RICH Company, many molecular sieve nitrogen generator manufacturers have sprung up in the chinese nitrogen generator industry. RICH Company has focused on the research and application of PSA pressure swing adsorption technology for 44 years. Through continuous technological innovation, it provides stable, reliable, energy-saving and high-quality complete sets of nitrogen generators/oxygen generators for various industries.

Using energy-saving molecular sieves

RICH Nitrogen Generator has high-performance molecular sieves that bring good equipment cost-effectiveness advantages. It has cooperated with well-known molecular sieve manufacturers at home and abroad for nearly 40 years. Energy-saving products can be selected according to the user's gas technology and working conditions. RICH has some new technologies. Unique purchasing rights for molecular sieves in the Chinese market.

The nitrogen generator produced by RICH is based on the principle of pressure swing adsorption and uses high-quality carbon molecular sieve as the adsorbent to produce nitrogen from the air under a certain pressure. The purified and dried compressed air is adsorbed under pressure and desorbed under reduced pressure in the adsorber. Due to the aerodynamic effect, the diffusion rate of oxygen in the micropores of the carbon molecular sieve is much greater than that of nitrogen. Oxygen is preferentially adsorbed by the carbon molecular sieve, and nitrogen is enriched in the gas phase to form finished nitrogen. Then the pressure is reduced to normal pressure, and the adsorbent desorbs the adsorbed oxygen and other impurities to achieve regeneration. Generally, two adsorption towers are set up in the system, one tower adsorbs to produce nitrogen, and the other tower desorbs and regenerates. The PLC program controller controls the opening and closing of the pneumatic valve, so that the two towers cycle alternately to achieve the purpose of continuous production of high-quality nitrogen. . The entire system consists of the following components: compressed air purification components, air storage tanks, oxygen and nitrogen separation devices, and nitrogen buffer tanks.
