Knowledge base: Nitrogen Generating Plant

Angstrom Advanced is the leading supplier of Nitrogen Generators for refinery, petrochemical and other industrial applications. Our services for Hydrogen Generating Plant projects typically include conceptual design, detailed engineering, procurement, fabrication, construction, start-up and operational training. We provide a lump-sum, turnkey solution, handling everything from concept to start-up with our own resources whenever possible.

Nitrogen Generator by Pressure Swing Adsorption (PSA)

PSA Nitrogen generator gets N2 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.

N2 capacity: 1-1200 Nm3/h
N2 purity %: 95%-99.999%
N2 Pressure: ≤0.8Mpa
Dew Point: ≤-40°C

Nitrogen Generator by Membrane Separation

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.

Gas Production (1-1000)Nm3/h
N2 Purity 95%-99.9%
N2 Pressure ≥0.8Mpa
Dew Point ≤-40°C

Nitrogen Purifying System

The purity of nitrogen generated by nitrogen generator is typical 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 deoxid-izing purifying system.

Gas Treatment 1-3000 Nm3/h
N2 Purity ≥99.9995%
Oxygen Content ≥5ppm
Dew Point ≤-70°C
