Pressure swing adsorption (PSA) is a technology used to separate some gas species from a mixture of
gases under pressure according to the species' molecular characteristics and affinity for an adsorbent
material. It operates at near-ambient temperatures and differs significantly from cryogenic distillation
techniques of gas separation.
Specific adsorptive materials (e.g., zeolites, activated carbon, molecular sieves, etc.) are used as a
trap, preferentially adsorbing the target gas species at high pressure. The process then swings to low
pressure to desorb the adsorbed material.
Pressure swing adsorption processes rely on the fact that under high pressure, gases tend to be
attracted to solid surfaces, or "adsorbed". The higher the pressure, the more gas is adsorbed; when
the pressure is reduced, the gas is released, or desorbed. PSA processes can be used to separate
gases in a mixture because different gases tend to be attracted to different solid surfaces more or
less strongly. If a gas mixture such as air, for example, is passed under pressure through a vessel
containing an adsorbent bed of zeolite that attracts nitrogen more strongly than it does oxygen, part or
all of the nitrogen will stay in the bed, and the gas coming out of the vessel will be enriched in oxygen.
When the bed reaches the end of its capacity to adsorb nitrogen, it can be regenerated by reducing
the pressure, thereby releasing the adsorbed nitrogen. It is then ready for another cycle of producing
oxygen enriched air.
This is the process used in medical oxygen concentrators used by emphysema patients and others who
require oxygen-enriched air to breathe.
Using two adsorbent vessels allows near-continuous production of the target gas. It also permits so-called
pressure equalisation, where the gas leaving the vessel being depressurised is used to partially
pressurise the second vessel. This results in significant energy savings, and is common industrial
The flow chart:
1.It operates quickly, qualified Hydrogen can be made immediately
2.The machine can fully automatic operate, without workers during the whole course
3.High efficiency molecular sieves filling, more compress, more solid, more lifelong
4.Pressure, purity, capacity can be made, to meet different customers needs.
5.Perfect structure, advanced procedure, stable@safety, little investment, lower consumption
