| A typical PSA (pressure swing
adsorber) gas generator producing high purity nitrogen at a customer
site |
| |
|
The Air Products’ PRISM ® PSA utilises proprietary technology
and the principles of adsorption to create a guaranteed reliable
supply of nitrogen gas.
|
|
| Dry compressed air enters the adsorber
bed, which is made up of a unique molecular sieve. The molecular
sieve selectively adsorbs both waste gases and oxygen. When the
sieve reaches saturation, flow is switched to a second bed, whilst
the first is regenerated. The cycle continues with nitrogen travelling
out of the bed, creating a continuous product stream which is fed
directly to the customer. |
