Air→ Air compressor → Pre-cooler → Purifier →Rectification column
and Turbo-expander →liquid oxygen tank or liquid nitrogen tank
Air 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 air compressor. Air from the air compressor
is cooled to 10℃ in the air precooling system and separated
condensing water in water separator. after the water being
separated its condensed water, taken into the molecular sieve
adsorber for removing H2O, C2H2 and CO2.
Then the cleaned air is divided into two streams, one of them is
taken into the rectifying column and cooled by the return waste
nitrogen, oxygen,expander air through the main heat exchanger. The
steam-liquid air mixture is taken into the lower column for
rectifying, and herein the pure nitrogen from the top of the column
enters into the evaporator-condenser and condensed by liquid oxygen
from the upper column. A part of the liquid nitrogen is fed to the
lower column as reflux. The other part after subcooling apart two
parts after throttled. One part enters into the top of the upper
column,other part enters storage tank as product(LIN).
Another cleaned stream is compressed in booster end of the booster
expansion turbine, then enters the main heat exchanger. air from
the middle and cold end of the main heat exchanger enter into the
turbine expansion to generate most refrigeration for need of the
plant's operation. After the expanded air return to heat exchange.
The LOX is drawn from oxygen side of the evaporator-condenser, some
of them enters storage tank as product.
To meet different demands from customers, different processes like
air cycle process ,nitrogen cycle process, high and low temperature
booster turbine expanding processor low temperature refrigerating
process etc. are adopted to reduce the power consumption. In order
to achieve stable and reliable operating of plant, PLC control
system or DCS control system are recommended.
We have supplied to many countries (Russia, Kazakhstan, Tajikistan,
India, Bangladesh, Thailand, Philippines, North Korea, Mongolia,
Equatorial Guinea, Botswana, Zambia, Angola, Tanzania) .
1. All unit machines are skid-mounted construction, connected by
fixed-size short pipe, after testing on supplier site, delivery the
plant together with all pipes and valve to User site, the User
needn't buy them by themselves, we make ensure the plant's perfect
2 The User only need prepare well the workshop, workshop ground and
crane is ok, needn't prepare other installation materials and
3 Small volume, occupied small area
4 Complete set of plant be installed without foundation, also has
following advantages: Stable running, easy operation, convenient
maintenance, without easy-damaged spare parts within two years.
5 To keep all valve's quality, the cold-valve of Rectification
column adopt the best-quality valve in Air separation Industry; The
Purifier valve adopt stainless steel valve, install thermostability
mat in it, ensure little wear, no cooling leak, no gas leak, long
life, during the long-term running.
6 All unit machines adopt the advanced technology, so reduce power
consumption greatly, save electricity fee.
7 The cooling way of plant is by air, the User needn't make cooling
water pool, save capital cost.
8 The installation and commissioning time is very short, it only
need 5-10 days.
