Product principle
The raw material of oxygen plant is air, the product is high purity oxygen, not only can be used as industrial oxygen can also be used for medical oxygen. Oxygen plant in the process of work without any emissions, and the only consumables is electricity. Oxygen generator is mainly composed of seven parts: air compressor, Pre-cooler, purification system(Purifier), expander, Rectification column, liquid pump, oxygen filling station.
The process is as follows:
Clean air via air compressor compressed to 1.05 MPa, and then into the Pre-cooler cold to 5-10 ºC or so, after the separation of water, into the purification system, adsorb the composition is contained in compressed air, such as acetylene, carbon dioxide and water. Clean and dry compressed air has entered the Rectification column heat exchanger, according to the three states of the material physical properties, separate the oxygen and nitrogen .After separation of the oxygen products by liquid oxygen pump compression pressure rise to the pressure of the user need, then pass through heat exchanger again, out of the coloumn, then through oxygen filling machine fill into the bottle or delivery to user site by pipe directly.
conditions of cold-heat changing alternately. The temperature changes range from 5ºC~200ºC. When temperature is
low, condensing-water corrode pipe, while the temperature is high, the pipe oxidized seriously. To ensure the life of
connecting pipe, and safety of plant, we have made heat insulation treatment on all the pipes.
2.11 To ensure the safe running of the plant, we equip four-stage pipe oil-filter to ensure that no oil can enter purifier
and rectification column. The pressure-difference meter in the four-stage pipe can also show the oil quantity to inform us to change the filter core, ensure the safety of follow-up plant. All filters are equipped with pressure-difference meter, we can judge the degreasing effect and the best time to change filter core, in this way we can prevent oil entering
system after the filter core lose efficacy.

Main Features
2.1 Each unit machine is skid-mounted construction, connected by fixed-size short pipe. the whole set of plant with all pipes and valve together are delivered to the User's site, the Users needn't to buy any additional spare part by themselves, we ensure the plant's perfect and integrate.
2.2 The User only need prepare well the workshop, keep the ground level is ok.
2.3 Adopting liquid oxygen pump inner-compress technology, we can produce high-quality medical oxygen with purity
range in 99.6-99.9%. The high quality oxygen products comply with the medical oxygen standard, widely used in medical and industrial area.
2.4 Small volume, covers an area of less, the complete set of plant only occupied 42M2(14m×3m).
2.5 Complete set of plant is installed without foundation, it has following advantages: stable running, easy operation,
convenient maintenance, without easy-damaged spare parts within two years.
2.6 To ensure all valves' quality, we adopt the best-quality valve in Air separation Industry produced as the cold-valve
in the Rectification column. We adopt stainless steel valve as the Purifier valve, and also install thermostability mat in
the stainless steel valve to ensure that the valve is of little wear, no cooling leak, no gas leak, long life in the long-term
running.
2.7 Advanced technology adopted in each unit can reduce power consumption greatly, and save electricity fee at the
same time.
2.8 Complete set of plant could be transported by car easily to suburban and faraway district. That can satisfy
customer's oxygen requirements in time in different areas.
2.9 It only takes about 15-20 days for the installation and commissioning.

2.10 The pipes used in the Purifier, including the connecting pipes between Purifier to Rectification column are in the
conditions of cold-heat changing alternately. The temperature changes range from 5ºC~200ºC. When temperature is
low, condensing-water corrode pipe, while the temperature is high, the pipe oxidized seriously. To ensure the life of
connecting pipe, and safety of plant, we have made heat insulation treatment on all the pipes.
