Pressure swing adsorption nitrogen production technology

The pressure swing adsorption nitrogen production technology adopts the principle of pressure swing adsorption. Under certain pressure, due to the dynamic effect, the diffusion rate of nitrogen and hydrogen molecules on the carbon molecular sieve varies greatly. In a short time, the oxygen molecules are absorbed by the carbon molecular sieve in a large amount. The molecules are enriched in the gas phase to achieve nitrogen and hydrogen separation. Since the adsorption capacity of carbon molecular sieve for oxygen varies significantly with pressure, reducing the pressure can desorb the oxygen molecules adsorbed by the carbon molecular sieve, so that the carbon molecular sieve can be regenerated, repeating the cycle alternately, and continuously producing high-quality nitrogen. .

What are the effects of altitude on human functions?

Ordinary people working or living on the plateau often cause discomfort due to lack of oxygen. According to survey statistics, 3000 meters above sea level is the critical altitude, and people with less than 3000 meters above sea level have less adverse symptoms; the climate characteristics above 3000 meters above sea level are very different from those in plain lowlands. As the altitude increases, more than 60% of people will be different. The degree of discomfort, hypoxia, or disease. The various symptoms that occur due to high altitude hypoxia are medically called inadequacy, commonly known as altitude sickness. Individuals have different adaptability to the plateau, and altitude sickness is also different. Some are temporary. As long as they adapt to the plateau environment for a period of time or leave the plateau environment, they will return to normal.

Working principle of pressure swing adsorption (PSA) oxygen generator

The pressure swing adsorption (PSA) oxygen generator uses zeolite molecular sieve as the adsorbent, and uses the principle of pressure adsorption and decompression desorption to adsorb and release nitrogen from the air, thereby separating oxygen. The zeolite molecular sieve is a special The spherical granular adsorbent with micropores on the surface and inside, which is processed by the pore type treatment process, is white. Its pore characteristics enable it to realize the kinetic separation of O₂ and N₂. The separation effect of zeolite molecular sieve on O₂ and N₂ is based on the slight difference in the dynamic diameter of these two gases. N₂ molecules have a faster diffusion rate in the micropores of zeolite molecular sieve, and O₂ molecules have a slower diffusion rate. The diffusion of water and CO₂ in compressed air is not much different from nitrogen. The final enrichment from the adsorption tower is oxygen molecules.

Why should the nitrogen generator be maintained? Why does the nitrogen purity of the nitrogen generator decrease?

The principle of pressure adsorption and decompression desorption is an automatic equipment that adsorbs and releases oxygen from the air, thereby separating nitrogen. Carbon molecular sieve is a kind of coal as the main raw material, after grinding, oxidizing, forming, carbonizing and processing through a special hole type treatment process, the surface and the inside of the columnar granular adsorbent with micropores are black, The pore size distribution characteristics of carbon molecular sieve enable it to realize the dynamic separation of oxygen and nitrogen. This pore size distribution allows different gases to diffuse into the pores of the molecular sieve at different rates without repelling any gas in the mixed gas (air). The separation effect of carbon molecular sieve on oxygen and nitrogen is based on the small difference in the dynamic diameter of the two gases. The dynamic diameter of oxygen molecules is small, so there is a faster diffusion rate in the micropores of carbon molecular sieve. The kinetic diameter is larger, so the diffusion rate is slower. The diffusion of water and carbon dioxide in compressed air is not much different from that of oxygen, while the diffusion of argon is slower. The final enrichment from the adsorption tower is a mixture of nitrogen and argon. After long-term use, the micropore diameter of the carbon molecular sieve will change; if the compressed air contains water and oil, the micropore diameter of the carbon molecular sieve will also be affected, thereby affecting the nitrogen production performance and reducing the purity of nitrogen. Therefore, the nitrogen generator needs regular maintenance.
