Product details description
ZSN pressure swing adsorption nitrogen generation equipment adopts the
high-quality carbon molecular sieve as the adsorbent, and uses the
pressure swing adsorption principle to directly obtain nitrogen from
compressed air.
Operating Principle
Under certain pressure, due to the kinetic effect, the diffusion
rate of oxygen and nitrogen on the carbon molecular sieve has a large
difference. Many oxygen molecules are adsorbed by the carbon molecular
sieve, and nitrogen molecules are enriched under the gas-phase condition
to achieve the separation of oxygen and nitrogen.
As
the carbon molecular sieve* s adsorption capacity for oxygen varies
with pressure, the pressure reduction may desorb the oxygen molecules
adsorbed by the carbon molecular sieve, so that the carbon molecular
sieve is regenerated and repeatedly used. Two adsorption tower processes
are adopted. One is to carry out adsorption and nitrogen generation,
and the other is to implement desorption and regeneration. Two processes
are repeatedly and alternatively used to continuously generate
high-quality nitrogen.
Technical Features
1. The labyrinth gas-flow diffusion device (national invention
patent) can make the gas flow evenly distributed, and greatly enhance
the utilization rate of the molecular sieve. The unique muffler device
(national patent) can effectively reduce the running noise of the
equipment.
2. Have complete process design, optimal use
effect, and unique protective measures for molecular sieves, to lengthen
the service life of the carbon molecular sieve.
3. The intelligent interlock unqualified nitrogen emptying device can ensure the quality of nitrogen.
4. The nitrogen device flow rate, automatic purity adjustment system, remote control system, and so on are optional.
5. Simple & convenient operation, stable running, and a high degree of automation may achieve the unmanned operation.
Typical Plant Configuration
1. Main Air Compressor(s), where the air is compressed up to the required process pressure
2. Pre-Treatment section for H2O and CO2 removal
3. Skid-mounted and supplied as a packaged unit
