99.9% N2 generator nitrogen generator for chemical industry

When the air pressure rises, the carbon molecular sieve will absorb a large amount of oxygen, carbon dioxide and moisture. When the pressure drops to normal pressure, the adsorption capacity of carbon molecular sieve to oxygen, carbon dioxide and moisture is very small.

The pressure swing adsorption generator is mainly composed of two adsorption towers A and B equipped with carbon molecular sieves and a control system. When the compressed air (the pressure is generally 0.8MPa) passes through tower A from bottom to top, oxygen, carbon dioxide and water are adsorbed by carbon molecules, while nitrogen is passed through and flows out from the top of the tower. When the molecular sieve adsorption in tower A is saturated, it will switch to tower B to carry out the above adsorption process and regenerate the molecular sieve in tower A at the same time. The so-called regeneration is the process of evacuating the gas in the adsorption tower to the atmosphere, so that the pressure quickly returns to normal pressure, and the oxygen, carbon dioxide and water adsorbed by the molecular sieve are released from the molecular sieve. The PSA nitrogen generator technology is a high-tech energy-saving separation technology that directly produces nitrogen from the air at room temperature, and has been applied for decades.
