DP-001 PSA ntrogen generator.

Introduction

PSA(Pressure Swing Adsorption) Nitrogen Generator is a new type hi-tech equipment with carbon molecular sieve adsorption, which uses compressed air as the feed material and molecular sieve as the adsorbent to produce nitrogen gas. Under the normal temperature and pressure, the adsorption and diffusion speed of oxygen in the molecular sieve is different from the nitrogen, thus, through the switch on/off of the PLC pneumatic valves, the oxygen and the nitrogen can be seperated by increasing the pressure for adsorbing and decreasing the pressure for desorbing to obtain the high purity nitrogen. The PDP series nitrogen plant produces nitrogen with purity from 95% to 99.999%. The production capacity ranges from 1Nm³/h to 3000 Nm³/h.

In case the user needs higher purity nitrogen, the DHD series nitrogen purifing unit could be attached to PSA nitrogen plant to increase the nitrogen purity up to 99.9999%, while the dew point could reach -70C°and the oxygen content is only about 2ppm.

Introduction of PSA process

After being compressed, purified, removed of oil, moisture and dust, the atmospheric air enters into the PSA unit composed of two adsorption columns filled with CMC(carbon molecular sieve).

When the compressed air pass through the column A , the oxygen is adsorbed by the CMC while the nitrogen flows into the nitrogen surge tank About 58 minutes later, when columns A and B have been balanced, the nitrogen is switched over to column B for the above-said process and column A vents the adsorbed oxygen through the silencer. Thus, the two columns do the adsorption and regeneration alternately to ensure the continual output of the nitrogen.

The pressure swing adsorption and recycling process includes: adsorbing, pressure balancing, pressure decreasing, releasing, flushing and than repressing, readsorbing…

Features of PSA nitrogen generator

1).Low Cost: PSA nitrogen generating is a simple and easy process with low energy consumption, which could produce nitrogen within several minutes after starting the equipment. The production cost is much lower than deep cryogmethed process and liquid buying from the market.

2). Reliable Performance: Controlled by imported micro-computer, the equipment operates automatically without specially trained operator. A simple push of the button would start the equipment and put out the nitrogen continually.

3).Stable Nitrogen Purity: The processing is supervised and indicated by instruments and required nitrogen purity could be ensured.

4). Imported High-quality Molecular Sieve: This CMC is characterized with big adsorption capacity, strong pressure-resistance and long life.

5).Imported High-quality Control Valves: The specially imported pneumatic valves guarantees the reliable operation of the nitrogen plant.

6).Strong Technology and Good Aftersales Service: The on-site installation only needs the special pipes and power supply. With guidance and regular feedback of the specialized technicians, the equipment could operate in a long-term stable condition.
