PRESSURE SWING ADSORPTIONGAS SEPARATION AND PURIFICATION

Purging gas

Absorbent

Absorbent

Hydrogen

FeedPressure swing adsorption is a process that separates single
gases from a gas mixture. It is mainly used in chemical andpetrochemical processes as well as the steel industry, for example to recover hydrogen (H2) from coking or conversion
gases, or to separate oxygen (O2) and nitrogen (N2) from air.

6The adsorption process is based on gas molecules binding
to an absorbent material. The adsorbent bed is speciallyselected depending on the gas to be absorbed. Ideally, only
the gas to be separated is adsorbed, while all other gasesin the mixture pass through the adsorbent bed. Frequently,© Caloric Anlagenbau GmbHabsorbents containing carbon (e.g. activated carbon or carbon molecular sieves) and oxide absorbents (e.g. zeolite)
are used. The purity of the absorbed gas not only depends
on the adsorbent used. The temperature and pressure during
the process are important as well. As a result, the control
valves used also contribute considerably to the quality of theend product.

2. Depressurization: depressurization is the first regeneration(desorption) step of the full absorbent bed. As the pressure
drops, the gas molecules in the adsorbent bed are released
and the target gas is discharged from the absorber vessel.

The pressure swing adsorption process is divided into fourstages that occur in cycles:

4. Repressurization: the absorber is pressurized using afeed gas mixture or the target gas until the process conditions for adsorption have been restored.

1. Adsorption: adsorption takes place at high pressure (upto 40 bar). The feed gas is fed through an adsorbent bed.
The absorbent binds the easily absorbable gas molecules,
while gas molecules that are not readily absorbable or notabsorbable at all pass through the bed. The absorbent bed
continues to absorb gas molecules until it reaches its fullcapacity.

3. Purging: the adsorbent bed is purged with the target gas
to fully regenerate it.

Usually, four to five adsorption vessels are combined so that
the PSA process can run continuously. While adsorption occurs in one vessel, the regeneration process and repressurization take place in the other vessels.

TESTING BEFORE THE LAUNCHOF THE SAMSON PFEIFFERTYPE 14P PSA BUTTERFLY VALVE
As part of an endurance test of the bi-directional highperformance butterfly valve for PSA applications, the seatleakage and external leakage (fugitive emissions) weretested in cycles with up to 1,000,000 load cycles.

The test was performed on the following specimen:

Seat leakage results Seat ring on disk: A479 316 Ti/HSB14
 Shaft seal: PTFE V-ring packing loaded by disk springs

with an upstream primary seal
 TA Luft (fugitive emission) certification
 Actuator: SAMSON PFEIFFER Type 31a SRP 900

During the cycle, 10 bar(a) air pressure were applied to theinlet of the valve. The outlet was exposed to the atmosphericpressure of p2 = 1 bar(a).
