Adsorption (PSA).PSA is a new gas separation technology, which has
been developed rapidly in foreign countries since the late 1960s
and early 1970s. Its principle is to separate the gas mixture by
the difference of the "adsorption" performance of different gas
molecules by molecular sieve. It takes air as raw material.The
nitrogen and oxygen in the air are separated by the selective
adsorption of nitrogen and oxygen with a high efficiency and high
selection of solid adsorbent.At present, carbon molecular sieves
and zeolite molecular sieves are used more in the field of nitrogen
and oxygen production.The separation of oxygen and nitrogen by
molecular sieve is mainly based on the different diffusion rates of
the two gases on the surface of molecular sieve. Carbon molecular
sieve is a carbon-based adsorbent with some characteristics of
activated carbon and molecular sieve.Carbon molecular sieves are
composed of very small micropores with pore sizes ranging from
0.3nm to 1nm.The smaller diameter of the gas (oxygen) diffuses
faster and more into the solid phase of the molecular sieve, so
that nitrogen enrichment can be obtained in the gas phase.After a
period of time, molecular sieve on oxygen adsorption balance,
according to the carbon molecular sieve under different pressure on
the adsorption of different gas adsorption characteristics, reduce
the pressure to remove the carbon molecular sieve on oxygen
adsorption, this process is called regeneration.PSA usually uses
two towers in parallel, alternately pressurized adsorption and
decompression regeneration to obtain a continuous flow of
nitrogen.With air as raw material, with carbon molecular sieve as
adsorbent, the use of pressure change adsorption principle, the use
of carbon molecular sieve on oxygen and nitrogen selective
adsorption and separation of nitrogen and oxygen method, commonly
known as PSA nitrogen.This method is a new technology of nitrogen
production which developed rapidly in 1970s.Compared with the
traditional method of nitrogen, it has simple process, high degree
of automation, produce gas quickly (15 ~ 30 minutes), low energy
consumption, product purity can be adjusted according to user needs
in a wide range, convenient operation and maintenance, low
operating cost, good adaptability device etc., in 1000 nm3 / h the
following competitive in nitrogen making equipment,PSA is more and
more popular among medium and small nitrogen users, and has become
the choice method for medium and small nitrogen users.Nitrogen
generator is divided into PSA pressure swing adsorption, and
membrane type, PSA is for screening as the main sorbent, membrane
is nitrogen machine is mainly separated by nitrogen film.Compact
low noise nitrogen generatorMembrane separation techniqueWhen
compressed air passes through the hollow fiber membrane, oxygen,
carbon dioxide and water vapor from the air are discharged into the
atmosphere through holes in the hollow fiber membrane pipes. At the
outlet of the membrane, large nitrogen molecules and the inert gas
argon are collected and transported to the application. This
nitrogen separation and extraction technology is simple and
effective, requiring no moving parts. The highest purity of
nitrogen can reach 99.5%.Pressure swing adsorption technology is
through solid medium to separate a single component of the gas
mixture, with pressure swing adsorption technology to separate
nitrogen in the air, the required solid medium is carbon molecular
sieve, carbon molecular sieve selective adsorption of oxygen in the
air, thus separating nitrogen and oxygen in the air under
pressure.Carbon molecular sieve is in fact porous and loose rod
like carbon particles, when filled with carbon molecular sieve
particles of nitrogen purification seal column filled with
compressed air (the main component is nitrogen, oxygen and inert
gas argon and a small amount of water vapor), carbon molecular
sieve will absorb water vapor, oxygen, but nitrogen will not be
adsorbed. This is mainly because the molecular si
