The PSA Gas Generators apply an optimized Pressure Swing Adsorption process for the separation of either the nitrogen or the oxygen in ambient air from the other gases.
A Nitrogen or an Oxygen PSA Generator contains either two single adsorption vessels (Twin-Tower systems) or a series of modules of two adsorption vessels (Modular systems), where each vessel is filled with an appropriate molecular sieve.
The gas production process starts by pressurizing one of the adsorption vessels with clean feed air. Before the equilibrium load is reached at the top of the adsorption bed, the feed air supply will be interrupted to prevent a break-through.
The adsorption vessels are alternatively loaded in order to guarantee a continuous product flow. If one adsorption vessel is loaded, simultaneously the other one is regenerated by a pressure decrease (desorption). The depressurization required for regeneration is obtained by simply venting to the atmosphere.
