Cryogenic Air Separation Nitrogen Generator - China

price: contact company for price

Air which was sucked in from air intake tower enters the

suction air filter and after being removed of dust and other

mechanical contaminants in it, it is compressed to the

pressure of 1.0MPa by piston air compressor. Air from the

air compressor is cooled to ~5℃ in the refrigeration unit,

taken into the molecular sieve adsorber for removing H2O,

C2H2 and CO2. There are two molecular sieve adsorbers which

operate on a staggered cycle, i. e. one vessel is adsorbing

the contained impurities while the other is being

reactivated by waste nitrogen from the rectifying column.

Then the cleaned air is taken into the rectifying column and

cooled by the return waste nitrogen, oxygen and nitrogen

through the main heat exchanger. The steam- liquid air

mixture is taken into the lower column for rectifying, and

herein the pure nitrogen of 99.99% from the top of the

column enters into the evaporator- condenser and condensed by

liquid air from the lower column. A part of the liquid

nitrogen is fed to the lower column as reflux.

In the main evaporator- condenser, liquid air is evaporated

to steam, then enters the main heat exchanger and get out

from the middle of the main heat exchanger and enter into

the turbine expansion to generate most refrigeration for

need of the plant' s operation. After the expander, air

enters to the main heat exchanger, and get out from the cool


The product nitrogen of 99.99% N2 gained at the top of the

lower column is warmed up through the main heat exchanger

and then taken to the user.

The waste nitrogen from the cold box is divide into two

parts, one part goes to the regeneration molecular sieve

adsorber system and the other part is vent.
