The PSA process is an extremely clean operation and the only ‘raw material’ is ‘air’. On-site generators allow for an uninterrupted supply of gas with a high purity output. This means that you can produce gas where and when you need it, and in the exact quantity and quality you need.
increases air to required level of pressure
removes moisture from air (air humidity) by cooling
3. Coal tower
adsorbs harmful organic impurities such as oil vapours and hydrocarbon compounds
4. Air tank
accumulates necessary volume of air for PSA generator
filling with its ion- exchange bed traps oxygen molecules and allows nitrogen molecules to stream through
6. High Purity Oxygen
flows from PSA generator to product tank and is ready for use
Nitrogen Generator System
How it works
- At Oxymat, we use two columns with molecular sieves to ensure continuous production.
- Dry compressed air is blown through a valve to the vessel where the pressure is built to reach 5 to 7 bar(g). Oxygen is tied to a molecular sieve during the building of pressure, and the nitrogen is allowed to pass through to the accumulation tank.
- While pressure is build in one vessel, the second remains without pressure.
- A part of the produced gas is used for regeneration of the molecular sieve.
- For Nitrogen a Carbon Molecular Sieve (CMS) is used. The molecular sieve is fully regenerative and has a life span on to 40.000 operation hours.
The entire PSA system can be subdivided into:
- Compressed air system (Air compressor, Refrigeration dryer, Air receiver & Filters)
- PSA skid
- Nitrogen receiver
- Nitrogen boosting & Filling Station (optional)
- Panel Display with electro galvanized sensor
- Touch Screen with zirconium sensor
- GSM modem for touch Screen
- Medical upgrade kit (Coalescing tower and bacterial filtration)
