Description:

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

practice.
