Nitrogen Plants

Angstrom Advanced PSA Nitrogen/Oxygen generator gets N2/O2 by pressure swing adsorption principle at normal temperature using clean compressed air as raw material and carbon molecular sieve as adsorbent. Because of the different adsorption of oxygen and nitrogen on carbon molecular sieve surface as well as different diffusion rate through the open/close of program control valve; separation of oxygen and nitrogen is achieved and N2 of required purify is created.
 
The compressed air compressor filter into the polymer membrane filters, a variety of gas in the film in the solubility and proliferation of different factors, leading to different gases in the membrane penetration rate in a relatively different. According to the characteristics, various gases can be divided into “rapid gas” and “slow gas”. After being compacted and purified (to remove oil, water and dust) the air will enter the membrane separation to separate. First, the O2, CO2 and some vapor will infiltrate into the membrane wall and then exit through the discharge port by air pressure; since the infiltrating speed of N2 is slower, it will flow out from the gas collector at the end of the pressure box and finally enter nitrogen buffer tank.
 
The purity of nitrogen generated by nitrogen generator can range from 95% to 99.99%. If higher purity is required, a non-hydrogen or hydrogen-using purifying system can be equipped.This system is installed after the Nitrogen Generator and further removes oxygen and other by-products.As a result, a final purity of 99.9995% or above is achieved. Angstrom Advanced Inc supplies the non-hydrogen deoxidizing purifying system and hydrogen deoxidizing purifying system.
Angstrom-Advanced Liquid Nitrogen/Oxygen/Argon Plant by Cryogenic Technology are top of the line systems.Our Generator applications range from 5-10000 liters of Liquid Nitrogen/Oxygen per hour and 1-500 Liquid Argon per hour.Cryogenic Engine features Fully Automatic G-M cold head with integral controls. Includes high efficiency frequency drive with water coolingor optional air cooling. Fully automatic PLC based controls provide many features and modes including auto start, timed run,auto purge, etc.Optional Chiller can be attached to liquefier unit when ordered at time of fabrication to allow continious operation up to 45 C.
