Oxygen Plant - PSA Technology

OxyNxtGen ONG Series Oxygen generators are on-site Oxygen generating plants. In the
model the plant contains the oxygen generator with the air compressor, air dryer and air
receiver tank with filter accessories as a inbuilt single unit, PSA module and oxygen Receiver
tank as separately floor mount.
Our oxygen generators working on the Pressure Swing Adsorption Technique.
Ozone Engineers OxyNxtGenTM oxygen generators uses imported zeolite based molecular
sieves. The delivery pressure can be set maximum 3 to 4 bar(g).
Basic Process Flow Description Of Oxygen Generator System
The normal flow of air through the PSA generator is shown in below picture. After exiting the
filter, the compressed feed air is regulated down to 4.0 – 6.0 bar(g) and then directed by
pneumatic activated valves into one of two absorber columns containing molecular sieve.
Molecular sieve has the unique property that it physically attracts or adsorbs nitrogen from the
air, leaving the oxygen to pass through to the product tank, and can when saturated with
nitrogen be regained to clean sieve again by purging with oxygen under lower pressure conditions
The PSA generator consist of two absorber columns working in alternate operation,
e.g. the processes always run in antiphase to one another in such way, that one absorber
column with cleaned sieve delivers oxygen while the other absorber column regenerates
saturated sieve.
After a certain pre-set period, the processes shifts, so that the first absorber column now
regenerates saturated sieve, while the second is delivering oxygen through a cleaned sieve.
The oxygen from the absorber column is stored in the product tank.
From the product tank the oxygen is regulated to 3-4 bar(g), depending upon model and
the consumer's specific working pressure. See below picture for more detailed information
on the working process.
