Container oxygen generator station for cylinder filling and direct hospital oxygen central supply

1 Specification:
Oxygen flow: 10 Nm3/hr
Oxygen purity: 93%
Oyxnge pressure: 150 barg
2 System combination
2.1 Air compressor
This system uses one screw air compressor to provide compressed air for whole system meeting following requirement:
FAD capacity: ≥2.2 m³/min (This data is based on 1000m altitude, 45℃max temperature)
Discharge pressure: 7.5 barg
Discharge oil content:≤3ppm

2.2 Air treatment part
This air treatment part consists of one front filter, one refrigerated dryer, two post filters plus one activated carbon oil remover. At the outlet of air treatment part, the compressed air meets the following specification:
Capacity:3.0 m³/min
Atmospheric pressure dew point: ≤-20℃
Oil content: ≤0.003mg/m3
Treated compressed air enters air buffer tank 2
2.3 Air buffer tank
Treated compressed air is stored in another 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:0.5 m³
Working pressure:8.0 barg
Material: Carbon steel
Safety valve, pressure meter, blow-down valve,etc parts are included.
2.4 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 Nm3/hr(20℃,101.3 kPa)
Oxygen purity: ≥93%
Dew point : ≤-45℃
2.5 Oxygen buffer tank 1
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:0.5 m³
Working pressure:8.0 barg
Material: Carbon steel
Safety valve, pressure meter, blow-down valve,etc parts are included.
2.6 Oxygen treatment part
The produced oxygen then enters one oxygen treatment part which has coalescing, microbiological filters to achieve clean and hygiene oxygen.
2.7 Oxygen buffer tank 2
Oxygen then enters one oxygen buffer tank to provide stable oxygen for downstream high pressure oxygen booster. This tank parameter is as below:
Volume:0.5 m³
Working pressure:8.0 barg
Material: Carbon steel
2.8 Oxygen compressor
In order to achieve oxygen pressure 150 barg, one oxygen compressor is equipped, which parameter is as below:
Capacity:10 Nm3/hr(20℃,101.3 kPa)
Inlet oxygen pressure::5.0 barg
Outlet oxygen pressure:150.0 barg
2.9 Oxygen filling station
In order to fill oxygen into cylinders, one oxygen filling station is supplied with 2 x 3, totally 6 filling positions, suitable for filling cylinders with CGA 540 valve.
2.10 Container(optional)
All parts can be installed in one 20gp container, with ventilation, heating, etc devices, can be moved from one place to another
