PSA Pressure Swing Adsorption Industrial Nitrogen Generator

Pressure swing adsorption (PSA) is a new gas separation technology. The principle is the separation of gas mixture adsorption performance difference molecular sieve different gases using air as raw material, and the use of a highly efficient, highly selective solid adsorbent selective adsorption of nitrogen and oxygen from the air nitrogen and oxygen separation. The separation effect of carbon molecular sieve on nitrogen and oxygen is mainly based on the different diffusion rates of the two gases on the surface of carbon molecular sieve. The smaller diameter of the gas (oxygen) under different pressure diffusion rate is faster, into the solid phase adsorption gas, reduce the pressure, so that the carbon molecular sieve release of oxygen adsorption. This process is called regeneration. Pressure swing adsorption (PSA) usually uses two parallel towers alternately for pressure adsorption and decompression regeneration to obtain a continuous flow of nitrogen.

The raw air is taken from nature, and nitrogen can be produced only by providing compressed air and power supply. The equipment has low energy consumption and low operation cost

The purity of nitrogen can be adjusted easily. The purity of nitrogen is only affected by the amount of nitrogen exhaust. The purity of common nitrogen can be adjusted between 95% and 99.99%; The high purity nitrogen generator can be adjusted between 99% and 99.999%
