System combination

1 Air Compressor-Not included

This system uses Screw Air Compressor to provide compressed air source for whole system meeting following requirement:

FAD capacity: ≧2.2 m³/min (This data is based on 1000m altitude, 45℃ max temperature)

Discharge pressure: ≧0.70 MPa

Discharge oil content:≤3ppm

2 Air treatment part

Compressed air coming from the air compressor enters air treatment part, which includes filters, Adsorption Dryer and oil remover, at the outlet of air treatment part, the compressed air meets the following specification:

Capacity:3.0 m³/min

Normal pressure dew point: ≤-20℃

Oil content: ≤0.01mg/m3

Treated compressed air enters air tank

3 Air tank

Treated compressed air is stored in air tank, providing the big amount compressed air during oxygen separator two towers switch, reducing gas flow fluctuation when passing through air treatment part, optimize air treatment effect. Air tank specification is as below:

Volume：0.3 m³

Working pressure：0.8 MPa

Material: Carbon steel

Safety valve, pressure meter, blow-down valve,etc parts are included.

4 Oxygen separator

This system uses PSA(pressure swing adsorption) technology, two adsorption towers alternatively work, constantly separate oxygen from air. Main oxygen specification is as below:

Flow rate    : 10.0 Nm3/hr （20℃，0.101MPa）

Oxygen purity: 93%

Dew point    : ≤-45℃

Outlet pressure: ≥5 bar(G)

5 Oxygen buffer tank

Oxygen coming from oxygen separator is buffered and effectively mixed in oxygen buffer tank, ensuring the stability of oxygen pressure, purity and flow rate. It also provides blowing back oxygen for fast pressure increasing during two adsorption tower operation switch, further improve oxygen production ratio. At the outlet, there are flow, pressure and purity test instruments, realize oxygen real time monitoring. Oxygen buffer tank parameter is as below:

Volume：0.3 m³  

Working pressure：0.8 MPa

Material: Carbon steel

Safety valve, pressure meter, blow-down valve,etc parts are included.

6 Oxygen Compressor

In order to achieve oxygen pressure 150 barg, one piston oxygen compressor is equipped, which parameter is as below:

Capacity：10 Nm3/hr

Inlet pressure：0.5 MPa

Outlet pressure：15 MPa

7 Oxygen filling station

In order to fill oxygen into cylinders, one oxygen filling station is supplied with 2x3=6 filling positions
