Air Separation
plant (Oxygen Plant)
This plant is widely used in the fields of steel melting,
paper making, chemical industry and medical usage.
In 1983, we have exported one set of 150Nm3/h. Since that,
a number of 13 complete sets were exported to the world market.
One of them, the biggest one is 10000Nm3/h, The exporting
series are: 50Nm3/h, 150Nm3/h, 1000Nm3/h, 1500Nm3/h, 3000Nm3/h,
6000Nm3/h, 10000Nm3/h, 28000Nm3/h.
The air is only the material used in the plant. The main products
are Oxygen and Nitrogen (gaseous and liguid). If argon tower
matched, the argon will be got.
Purity:
| Oxygen (O2) |
99.5% |
| Nitrogen (N2) |
99.99% |
| Argon (Ar) |
99.999% |
If the customer doesn't need high purity of Oxygen (purity
90%-93%), we suggest you to use PSA (pressure Swing Absorber)
Oxygen Genoration plant. This plant is also widely used in
the fields of electric furnace steel-smelting, Nonferrous
metal smelting, Fertilizer producing gas, Industry heater
combustion-supporting, Casting cupola, Rich oxygen iron-smelting,
Oxygen evaporating-bleaching-block liquid oxygenation in papermaking
industry, using the waste water oxygen aeration & activated-sludge
to deal with industrial waste water and city sewage, Used
in all kinds of oxygenations, coal vaporation ozone generation,
naphtha decomposition & carbon block in chemical industry,
Ferment industry, superdensity feeding fish, lron-oxygen cement
in cement industry, Refractory brickmaking, Class processing.
For storage and long distance transportation of liquid oxygen
of liquid nitrogen, we cn supply liquid tank and liquid tank
with truck.
These series plants are producing the pure oxygen and nitrogen
from the air with a method of medium pressure cycle and cryogenic
refrigeration i. e. first product the liquid air using the
medium pressure recitrocating expansion engine, then in the
cold box, the liquid air is rectificated into gas oxygen with
a purity of 99.5% and gas nitrogen with q purity of 99.99%
by means of their different boiling point. These plants also
can produce a bit of liquid oxygen and nitrogen, and medical
oxygen after changing some parts, if any.
Model KZON150/600 can be matched a unit of argon device with
a capacit of 3 MN/H with a purity of 99.999%.
These plants are particularly suitable to the chemical. electronic.
metallurgical. mechanical and synthetic fibre industries and
the medical treatment.
