PSA Nitrogen Generator Ensures The Stable Operation

The long service life of the valve and key parts of PSA nitrogen generator ensures the stable operation

Working Principle Description

PSA nitrogen generator uses compressed air as raw material and uses an adsorbent called carbon molecular sieve to selectively adsorb nitrogen and oxygen to separate nitrogen from the air.

The separation effect of carbon molecular sieve on nitrogen and oxygen is mainly based on the kinetic effect. The diffusion rate of oxygen molecules with smaller kinetic diameter in the micropores of carbon molecular sieve is much higher than that of nitrogen molecules, and more oxygen molecules with smaller diameter enter the solid phase of carbon molecular sieve. In this way, before the adsorption reaches equilibrium, nitrogen molecules are enriched in the gas phase to obtain product nitrogen. After a period of time, the adsorption of oxygen molecules by molecular sieve reaches a certain degree. Through decompression, the gas adsorbed by carbon molecular sieve is released, and the regeneration of carbon molecular sieve is completed.

This is based on the different adsorption capacity of carbon molecular sieve for adsorbed gas under different pressure. Pressure swing adsorption nitrogen production unit usually uses two parallel adsorbers to alternately carry out pressurized adsorption and decompression regeneration, with an operation cycle of 2 minutes.

Application fields:

Nitrogen, commonly referred to as inert gas, is used in some inert atmospheres for metal treatment and in bulbs to prevent arcing, but it is not chemically inert. It is an essential element in animal and plant life and an integral part of many useful compounds. Nitrogen combines with many metals to form hard nitrides, which can be used as wear-resistant metals. A small amount of nitrogen in steel will inhibit grain growth at high temperature and improve the strength of some steels. It can also be used to produce a hard surface on steel. Nitrogen can be used to produce ammonia, nitric acid, nitrate, cyanide, etc; In the manufacture of explosives; Filled high temperature thermometer, incandescent bulb; Form inert material to preserve the material and use it in a drying oven or glove bag. Liquid nitrogen during food freezing; As a coolant in the laboratory.
