PSA process for nitrogen generation
|
|
Pressure
Swing Adsorption (PSA)
|
The
nitrogen generation plant based on the PSA-process consists of two adsorption
towers filled with Carbon Molecular Sieve (CMS). Compressed and purified
air is passed through the adsorption towers. Mainly Oxygen is adsorbed
on the CMS and Nitrogen enriched gas leaves the tower. The oxygen concentration
can be reduced to almost all required levels.
During adsorption in one tower the second tower is totally regenerated
just by depressurisation to ambient pressure. The oxygen enriched off
gas with 30 - 35% volume Oxygen content is vented to atmosphere. About
one minute the adsorption in one adsorption tower the process controller
switches over to the second tower and the first one is regenerated.

Above:
Membrane process for nitrogen generation |
The
membrane system consists mainly of parallel membrane modules, inside
equipped with thousands of hollow fibres. Compressed and purified
air passes through these hollow fibres which separate the oxygen molecules
from air. Due to the different molecule diameters of the air gases,
the oxygen molecules penetrate faster through the hollow fibres surface
than the nitrogen molecules. Nitrogen enriched gas leaves the hollow
fibres as the gas produced. Mainly the flow velocity through the hollow
fibres effects the remaining oxygen content.

There is a wide range
of nitrogen generators and plants available including standard models
- the GA Range and custom designed plants. If your requirements are
different frrom the systems detailed in the GA
Range, we can provide you with details on larger systems to meet
your needs and application covering PSA, Membrane or VPSA technology.
Further information on larger system can be provided if you phone us
or send us an email at info@onsitegenerating.com
solutions or compete the Contact Form providing as much
information on your usage as possible.
