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.

4. Characteristics of nitrogen production equipment:
★ The advanced adsorber structure is designed with the best
proportion in combination with the size of the air flow and the
adsorption characteristics of molecular pa.
★ The unique air distributor design makes the air flow in the
adsorption bed more uniform and greatly improves the utilization
rate of the adsorbent. ★ The unique air inlet mode+cylinder
compression device can effectively avoid the pulverization of the
adsorbent and ensure the working life of the adsorbent for more
than 10 years. ★ -- Step method for producing high-purity nitrogen:
it is possible to directly produce nitrogen with purity of 99.995%
or more without purification.
★ Advanced energy-saving design process ensures that the highest
nitrogen output can be obtained with the lowest raw air
consumption, and the energy saving of the product can reach more
than 10%. The key parts and components are made of internationally
famous crystal brand, which can guarantee the normal service life
of more than 10 years.
★ Intelligent full-automatic control. No special person is required
to take care of: electrical automatic interlocking protection can
realize remote DCS control.
★ Advanced design technology and sophisticated manufacturing
technology ensure long-term stable operation of the equipment. The
equipment is maintenance-free at ordinary times.
★ Helium purity and flow are monitored online, so that users can
keep track of equipment dynamics at any time.
★ The gas production is fast, and qualified ammonia can be produced
within 15 minutes after starting up: it is easy to start and stop,
and it is easy to start and stop.
