Psa Nitrogen Generator for Pharma Industry

PSA Nitrogen Generator

Full name: Pressure Swing Adsorption (PSA).

PSA is an innovative gas separation technology that has seen rapid development in many countries since the late 1960s and early 1970s. The principle behind PSA involves separating gas mixtures based on the differing adsorption properties of various gas molecules using molecular sieves. Utilizing air as the raw material, this process efficiently separates nitrogen and oxygen through the selective adsorption of these gases by a high-efficiency, high-selectivity solid adsorbent.

Currently, carbon molecular sieves and zeolite molecular sieves are widely used in nitrogen and oxygen production. The separation of oxygen and nitrogen by molecular sieves is primarily based on the differing diffusion rates of these gases on the molecular sieve surface. Carbon molecular sieves, which possess characteristics of both activated carbon and molecular sieves, consist of very small micropores ranging from 0.3nm to 1nm in size. The smaller gas diameter (oxygen) diffuses more rapidly into the solid phase of the molecular sieve, resulting in nitrogen enrichment in the gas phase. Over time, the molecular sieve reaches an adsorption equilibrium for oxygen. By adjusting the pressure, the adsorption of oxygen on the carbon molecular sieve can be reduced, a process known as regeneration. PSA typically employs two parallel towers, alternating between pressurized adsorption and depressurized regeneration to ensure a continuous nitrogen flow.

Using air as the raw material and carbon molecular sieves as the adsorbent, the PSA method leverages pressure change adsorption principles to selectively adsorb and separate nitrogen and oxygen. This technology, which emerged in the 1970s, offers a simple process, high automation, rapid gas production (15-30 minutes), low energy consumption, adjustable product purity, easy operation and maintenance, low operating costs, and good device adaptability. For nitrogen production below 1000 nm3/h, PSA is increasingly favored by medium and small nitrogen users and has become the preferred method for such applications.

working principle
According to the principle of pressure swing adsorption, high-quality carbon molecular sieves are used as adsorbents. Under a certain pressure, due to kinetic effects, there is a significant difference in the diffusion rates of oxygen and nitrogen on carbon molecular sieves. By utilizing the large amount of oxygen molecules adsorbed by carbon molecular sieves, nitrogen molecules are enriched in the gas phase, achieving oxygen nitrogen separation.
Due to the significant difference in oxygen adsorption capacity of carbon molecular sieves with different pressures, reducing the pressure can desorb the oxygen molecules adsorbed by the carbon molecular sieve, regenerate the carbon molecular sieve, and enable repeated recycling.
Adopting two adsorption tower processes, one tower adsorbs and produces nitrogen, while the other tower desorbs and regenerates, with alternating cycles to continuously produce high-quality nitrogen gas.
