PRESSURE SWING ADSORPTION
Pressure Swing Adsorption can be used to produce N2 or O2 from compressed air, which is fed to the unit that uses adsorption phenomena to remove the contaminants: N2 when the desired pure gas is O2, or O2 when the desired pure gas is N2. Also, in both cases, H20 and CO2 are removed as well as other minor contaminants.
The PSA unit contains two tower packed with a selective adsorbent that has affinity towards the component to be removed: a carbon molecular sieve is used to produce N2 and zeolites are used to produce O2.
Each tower undergoes a cyclic sequence of high and low pressure steps that guarantees the production of a continuous flow of high purity gas In the high-pressure step, the adsorbent retains the contaminants present in the compressed air and the desired gas (N2 or O2) is obtained from the top of the columns. The regeneration is accomplished in the low-pressure step, with the release of contaminants retained by the adsorbent.
