PSA pressure swing adsorption nitrogen production equipment:
1. PSA pressure swing adsorption nitrogen production principle:
Under a certain pressure, carbon molecular sieve adsorbent is used
to separate high air by taking advantage of the different diffusion
rates of oxygen and nitrogen in the air in the pores of carbon
molecular sieve. That is, the diffusion adsorption of oxygen on
carbon molecular sieve is far greater than that on helium, so the
oxygen in the air (carbon dioxide, water vapor, etc.) is first
adsorbed; Nitrogen is enriched through the adsorption bed and
exported as product gas. When the components adsorbed by the
adsorbent in the tower tend to be saturated, the atmospheric
desorption is carried out to regenerate the adsorbent: the clean
compressed air after the pretreatment of oil removal, water removal
and dust removal enters another adsorption tower to continue to
adsorb and produce nitrogen. The programmable controller PLC
controls the opening and closing of each valve in the pipeline
system, pressurized adsorption, and depressurized desorption to
achieve the alternate cycle of the two adsorption towers to
complete the connection and nitrogen production. This process is
PSA pressure swing adsorption nitrogen generation.

No | MAIN PART | FUNCTION | ||
1 | Air compressor | Air is used as raw material to collect & compress air to 8 bar,
(Screw type) | ||
2 | Refrigerated dryer | The standard configuration removes moisture and impurities in the
air, so that the air dew point reaches -20°C (the intermediate
configuration uses an adsorption dryer, and the dew point reaches
-40°C; the advanced configuration uses a combined dryer, and the
dew point reaches- 60ºC). | ||
3 | Precision Filter | A/T/C three-stage filter to remove oil, dust and impurities. | ||
4 | Air buffer tank | Store pure and dry air for subsequent adsorption and separation of
oxygen and nitrogen as raw material storage. | ||
5 | Adsorption tower | A&B adsorption tower can work alternately, regenerating
adsorption, filling sodium molecular sieve to filter out oxygen
molecules. | ||
6 | Analyzer | Real-time monitoring and analysis of oxygen & nitrogen purity,
indicating that the equipment is working normally and alarming. | ||
7 | Valves & pipelines | Intelligent control valves realize automatic operation of
equipment, PLC control, SUS304 pipelines. | ||
8 | Gas Buffer Tank | Store oxygen & nitrogen with qualified purity, which can be
directly piped or used for bottle filling. | ||
9 | Pressure regulator | Adjust and temperature the outlet pressure of oxygen & nitrogen
(3-6 Bar). | ||
10 | Dust filter | Remove the dust brought by molecular sieve in oxygen & nitrogen | ||
11 | Check valve | Prevent oxygen & nitrogen back flow | ||
12 | Gas Booster | Pressurize the oxygen&nitrogen to the filling pressure,
generally 150bar or 200bar. | ||
13 | Filling Manifold | Split high-pressure oxygen & nitrogen into each gas cylinder | ||
