Treatment Information
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. Special absorptive materials (e.g., Granulated Carbon,
zeolites) are used as a molecular sieve, 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 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 gas.
Pressure Swing Adsorption Process
It also permits so-called pressure
equalisation, where the gas leaving the
vessel being de-pressurised is used to
partially pressurise the second vessel.
This results in significant energy savings,
and is common industrial practice.

PSA systems are one of the most
economical method to separate carbon
dioxide from methane gas, Using inlet
pressure above 30 psi, the only
requirement is the vacuum pump to
remove the CO2 from the adsorption
