Pressure swing adsorption nitrogen production equipment

Working principle 

The device uses carbon molecular sieve as the adsorbent, adopts the principle of pressure swing adsorption to obtain nitrogen.

        Adopting two or more towers of the adsorption tower process, the process is controlled by PLC, one tower absorbs for producing nitrogen and the oother one stops desorbing for regenerating, and the two towers work alternately to continuously produce high-quality nitrogen.

 Features

•  Low energy consumption, stable performance, fast gas production, adjustable output and purity  ;

• Integrated skid structure design, easy installation and operation, small footprint;

• Intelligent control, can realize unmanned operation;

• Unique self-operated compression protection device to extend the service life of carbon molecular sieve;

• Use well-known brand pneumatic valves to ensure continuous operation of the equipment ;

•Automatic venting device for unqualified nitrogen to ensure the quality of finished nitrogen;

• Various fault diagnosis, alarm and processing functions ;

• Options of touch screen man-machine interface, adaptive energy-saving control, dew point detection, DCS communication, etc.

VPSA oxygen production equipment

Working principle： 

The vacuum pressure swing adsorption oxygen production equipment uses high-quality oxygen production molecular sieve to adsorb nitrogen, and the unadsorbed oxygen gathers at the top of the tower and is transported to the oxygen storage tank as product gas. When the adsorption tower in the adsorption state is close to saturation, the tower will automatically decompress and desorb and regenerate, and the other adsorption tower will begin pressurized adsorption to produce oxygen. The two adsorption towers work alternately to complete the oxygen production process.

Technical features:

（1）The amount of civil works is small, the installation period of the device is shorter than that of the cryogenic device, and the investment is low ;

（2） Low energy consumption for oxygen production, and low equipment operation and maintenance costs;

（3）The device has a high degree of automation, it is convenient and quick to start and stop, and requires fewer operators ;

（4）The device has strong operation stability and high safety ;

（5）The operation is simple, and the main components are selected from internationally renowned manufacturers ;

（6）The original imported oxygen molecular sieve is used, which has superior performance and long service life.
