Industrial PSA Nitrogen Generator With Carbon Molecular Sieve Sorbent

PSA Nitrogen Generator, With Carbon Molecular Sieve Sorbent, Industrial
Application



PSA Nitrogen Generator Principles:


PSA nitrogen generator uses a carbon molecular sieve as sorbent and produces
nitrogen by making use of the PSA principle. Under certain pressure, a carbon
molecular sieve has different oxygen/nitrogen adsorption capacity, i.e. much
more oxygen adsorption capacity than nitrogen adsorption capacity. PLC controls
the pneumatic valve on/off to realize two towers alternate adsorption and
desorption as per pressure change, carries out oxygen/nitrogen separation, and
produces nitrogen with desired purity.
PSA Nitrogen Generator incorporates one air compressor, refrigerant air dryer
and filters, main nitrogen generator, air buffer tank, and nitrogen buffer
tank. With higher nitrogen pressure required, one BROTIE totally oil-free
nitrogen compressor will be equipped after the nitrogen generator to increase
the nitrogen pressure to the required pressure.
Compressed air is purified through the air dryer and filters to a certain level
for the main generator to work with. Air buffer is incorporated for a smooth
supply of compressed air thus reducing the fluctuation of work demand for air
compressors. The generator produces nitrogen with PSA (pressure swing
adsorption) technology, a time-proven nitrogen generation method. Nitrogen with
a desired purity is delivered to a nitrogen buffer tank for a smooth supply of
product gas. Nitrogen in the buffer tank is maintained at 6barg pressure. After
a totally oil-free nitrogen compressor, the pressure will be compressed to the
required pressure. It is adjustable for you to adjust the outlet pressure by a
pressure regulator valve, so that it can be used for your specific use.

Brief Principles

Each gas has a characteristic adsorption rate when adsorbed by Carbon Molecular
Sieve (CMS). CMS has a large surface area containing a volume of micro pores
and passageways. Oxygen has a higher adsorption rate than nitrogen. When
compressed air enters CMS, nitrogen molecules are able to pass through this
large surface. And oxygen molecules are adsorbed to the surface area.
As the CMS is saturated with oxygen, it should be depressurized to regenerate
for the next cycle. We use two towers filled with CMS to produce a continuous
stream of nitrogen.
During depressurization, the nitrogen of lower purity than required is
transferred to another tower called pressure equalization. Pressure
equalization donates to higher efficiency and less energy consumption.
Know-how in the definite time and ways to equalize the pressure is the key to
the best results.

When the process adopts lifting air, oxygen and nitrogen have different
diffusion rate and adsorptive capacity to separate oxygen from nitrogen on a
carbon molecular sieve(CMS). When air is compressed

to 0.8MPa, the air source enters in pressure-swing adsorption tower for
separation after being purified through the dry and oil-water separation
process (filter). Oxygen molecules are diffused and adsorbed in a carbon
molecular sieve under pressure. Non-adsorbed nitrogen is discharged from the
outlet of the adsorption tower. Oxygen is desorbed, discharged, and purged in
an adsorption tower under depressurization. Moreover, adsorbents can be
recycled. Paige brand.
