Pressure swing adsorption technology is an advanced gas separation technology

The main principle is: extraction of nitrogen diffusivity due to the surface air of two oxygen and nitrogen microporous gas molecules, in the carbon molecular sieve, molecular oxygen diffusion speed and diameter is smaller, into the molecular sieve more solid (micro), nitrogen molecular diameter is larger diffusion is slow, in the molecular sieve solid (micro) is small, so just to get a nitrogen rich gas in the gas phase; Under the adsorption equilibrium condition, the adsorption of carbon molecular sieve is larger when the air pressure is higher. When the pressure is lower, the adsorption capacity is smaller.

The industrial operation of the PSA air separation nitrogen plant generally has two or more adsorbent compositions, and the adsorber is optimized through circulation to achieve continuous production and nitrogen efficiency.

After clean and dry compressed air, swing adsorption acts to form a complete nitrogen. In the conventional setup of two adsorption tower systems, the nitrogen adsorption capacity of one tower, not tower desorption regeneration. The pneumatic valve is controlled by the PLC program of opening and closing, and the two towers are circulated to achieve the purpose of continuous production of high-quality nitrogen.
