Raw Air Composition
The Plant uses normal temperature molecular sieve adsorption,
medium pressure booster expansion reflux flow.
Raw air is sucked from the atmosphere, It is going through filter
for removal of dust and mechanical impurities., then it is
compressed to a certain degree by single stage screw compressor,
via end stage cooler, air pre-cooling system, the air is cooled to
approx. 8ºC. After water separation moisture is separated in water
separator and then it goes to purifier for removal of moisture,
CO2, C2H2 and hydrogen dioxide.
Then most part of air enters main heat exchanger to be cooled to
saturated tempt. and partly is liquefied to the lower part of lower
column; another part of air is compressed to a certain degree
through two stage compression booster, via end stage cooler enters
into oxygen heat exchanger to be cooled to be near saturated
temperature, then after throttle goes to lower column. Through
lower column pre-distillation we can get enriched oxygen liquid air
from the bottom of the column. After cooling through sub-cooler,
after throttled it goes to the middle part of upper column as
reflux liquid for rectification. WN is obtained from the top of
lower column, after condensed through condenser-evaporator, a part
of WN is used as rectification reflux liquid for lower column;
another part after cooling through sub-cooler and after throttling
goes to the top of upper column as rectification reflux liquid.
Pure liquid oxygen is obtained from the bottom of upper column, and
it is condensed by condenser-evaporator. Liquid oxygen is
abstracted from the bottom after cooling through sub-cooler, then
it goes to LOX pump to be pressurized. It is evaporated in O2 heat
exchanger and is reheated to normal tempt and then directly goes to
oxygen filling ramp for filling of cylinders.
WN from the top of upper column goes through sub-cooler, the ower
part of main heat exchanger to be reheated to a certain tempt. Then
it goes to expansion turbine to create cold and returns to
sub-cooler and main heat exchanger again to be reheated to normal
tempt. A part of it passes to purifier as regenerating gas resource
and another part goes to be vented partly.

* This oxygen plant adopts cryogenic separation process. Oxygen is
obtained by inner compression, so it
can be both for medical & industrial usage and to be filled
* This development and design of flow is new, my company use the
technology to mature.
* Simple operation, convenient maintenance, starting time is short,
unit power consumption is low.
* Oxygen of high purity and very stable, meet and exceed technical
indicators of 2010in china.
* Whole set of plant adopts skid mount type and connected with
high-pressure hose between individual
machines/equipments. So, it shorten installation period
* Complete equipment, installation and removal is very simple, easy
to move to another area operations.
* Cooling mode of plant adopts air cooling for whole set of plant,
no cooling water system required so it also
save investment cost for the owner.
* Security -- The outside compression process is oxygen be
compressed at room temperature, The inside
compression process is liquid oxygen be compressed at low
temperature, Security than more with the inside
compression process； Extraction a lot of liquid oxygen from
evaporation-condenser, To ensure that no
accumulation of hydrocarbons; Evaporation of high pressure with
liquid oxygen, reducing the possibility of
hydrocarbon accumulation; Reducing fire hazards.
* Reliability - liquid oxygen pump excellent performance, easy to
maintain; Booster compressor is one or two
compression, oxygen compressor Booster compressor is three or five
compression, High reliability with
