Product Description

Nitrogen, as the most abundant gas in the air, is inexhaustible and inexhaustible. It is colorless, odorless, transparent, subinert and does not support life. High purity nitrogen is often used as a protective gas in places where oxygen or air is isolated. The content of nitrogen (N2) in the air is 78.084% (the volume group of various gases in the air is divided into N2:78.084%, O2:20.9476%, Argon: 0.9364%, CO2: Other H2, CH4, N2O, O3, SO2, NO2, etc., but the content is very small), molecular weight is 28, boiling point: -195.8, condensation point: -210.

Pressure swing adsorption (PSA) nitrogen production process is pressure adsorption, atmospheric desorption, must use compressed air. The best adsorption pressure of carbon molecular sieve used now is 0.75~0.9MPa. The gas in the whole nitrogen production system is under pressure and has impact energy. Two, PSA nitrogen production principle: JY/CMS pressure change adsorption nitrogen machine is carbon molecular sieve as adsorbent, using pressure adsorption, step-down desorption principle from the air adsorption and release of oxygen, so as to separate the automatic equipment of nitrogen. Carbon molecular sieve is a kind of coal as the main raw material, after grinding, oxidation, molding, carbonization and processed through special groove processing technology, surface and internal cylindrical granular adsorbent that is full of pores, in black ink, the groove distribution as shown in the figure below: carbon molecular sieve pore size distribution characteristics of O2, N2, so it can realize dynamic separation. This pore size distribution allows different gases to diffuse into the pores of the molecular sieve at different rates without repelling any of the gases in the mixture (air). The effect of carbon molecular sieve on the separation of O2 and N2 is based on the small difference in the kinetic diameter of the two gases. O2 has a small kinetic diameter, so it has a faster diffusion rate in the micropores of carbon molecular sieve, while N2 has a large kinetic diameter, so the diffusion rate is slower. The diffusion of water and CO2 in compressed air is similar to that of oxygen, while argon diffuses slowly. The final concentration from the adsorption column is a mixture of N2 and Ar. The adsorption characteristics of carbon molecular sieve for O2 and N2 can be intuitively shown by equilibrium adsorption curve and dynamic adsorption curve: from these two adsorption curves, it can be seen that the increase of adsorption pressure can make the adsorption capacity of O2 and N2 increase at the same time, and the increase of O2 adsorption capacity is larger. The pressure swing adsorption period is short, and the adsorption capacity of O2 and N2 is far from reaching equilibrium (maximum value), so the difference of diffusion rate of O2 and N2 makes the adsorption capacity of O2 greatly exceed that of N2 in a short period of time. Pressure swing adsorption nitrogen production is the use of carbon molecular sieve selective adsorption characteristics, the use of pressure adsorption, decompression desorption cycle, so that compressed air alternately into the adsorption tower (can also be completed by a single tower) to achieve air separation, so as to continuously produce high purity product nitrogen.
