Working principal
In cases where the air passes within the pressure through a vessel consuming an absorbent bed of CMS that has a capability of attracting the oxygen more strong if compared to the nitrogen. Thus, the oxygen stays in the bed and the gas that comes out of the vessel claimed to be enriched in nitrogen. While, if the bed reaches to the top of its capacity to absorb oxygen, then it can easily be regenerated by reducing the pressure and releasing the absorbed oxygen. Thus, in the same procedure, another cycle to produce nitrogen forms.
PSA also claimed as pressure swing adsorption which is known as the best air separation technology. It is one permanent and the irreplaceable standing on-site gas supply field. Under the condition of the adsorption balances, for any adsorbent when one sort of gas is adsorbed, then it is proved that the higher the air pressure, the best quantity can be adsorbed and thus vice versa. As discussed before, in a condition where the pressure is high, the more value of oxygen, carbon dioxide and water will be absorbed by the carbon molecular sieve. While, on the othe5r hand where the pressure is the same as the atmospheric pressure, the adsorbing capacity of the carbon molecular sieve to oxygen, carbon dioxide and water reduce. The PSA equipment is built of two adsorption tower i.e. A and B with the special installation of the carbon molecular sieve and the control system. The process works as when the clean compressed air enters through the tower A and exits through the side of the carbon molecular sieve (mostly at the pressure of 0.8MPa), O2, CO2 and H2O. While, on the case of nitrogen products, it flows out from the top of the adsorption tower. After some time, the carbon molecular can easily be observed in tower A. where, the tower A automatically stop the process of adsorbing, thus the compressed air flows into the tower B to carry out the oxygen adsorption and the nitrogen production and from tower A the regeneration to the molecular sieve is processed. This process of regeneration is the way of discharging the gas of the adsorption tower to the atmosphere to bring the pressure equal to the atmospheric pressure.
The adsorption separation is accomplished in the following process steps:
Stages of PSA technology-
- Feed air compression and conditioning- in this step the ambient air is compressed with the help of air compressor, and in the same way, dried by an air dryer and then the filtration process is covered before entering the process vessels.
- Pressurization and adsorption- the pre-treated air is then served into a vessel filled with the carbon molecular sieve wherein the CMS pores the adsorbed oxygen is preserved so that the nitrogen with an adjustable purity remains in the gas stream. Before the complete utilization of the carbon molecular sieve, the nitrogen separation process gets interrupted and thus, the switching of the adsorber vessels are initiated.
- Desorption- in this step the adsorbed gases are released by the means of different pressure reduction steps. This process can be easily achieved by the pressure release system. The waste stream occurs, as a result, is vented into the atmosphere. Thus, the regenerated adsorbent can be used for generating nitrogen.
- Nitrogen receiver- the adsorption and desorption processes work simultaneously, which means that the continuous generation of nitrogen can be obtained with the help of two adsorbers, one working at adsorption and the other one at regeneration. With this constant product flow and purity is ensured where the purity ranges up to 99.995% and pressure up to 7.5 bar (g)/ 110 PSIG.
- Nitrogen product- the result is a constant outcome of on-site produced high purity nitrogen.
