PSA oxygen generator
PSA (Pressure Swing Adsorption) Technology is a revolution in Non-Cryogenic Air Separation and
Oxygen Generation Technology uses a special grade of ZMS (Zeolite Molecular Sieve).
The compressed air is passed through a Twin Tower PSA module interconnected with an automatic
changeover valves. After passing through a Refrigerated Dryer air gets dried. Dried compressed air
will now come in contact with the bed of Zeolite molecular sieves (ZMS). Zeolite Molecular Sieves are a special
grade of adsorbent that has the property of preferential adsorption of nitrogen molecules. At a time
one tower remains under the nitrogen production cycle, whereas the other tower undergoes regeneration
which is achieved through depressurization of the tower to atmospheric pressure. The outgoing oxygen
gas is sent to a surge vessel where the minimum pressure will be maintained with the help of a Backpressure Regulator
Principle:
The traditional methods of making oxygen need to cool air into liquid (about-180ºC), via exacting to get oxygen. PSA oxygen generator under normal temperature, and normal pressure working, had the following advantages:
1. Lower cost, PSA oxygen system choosing special ZMS CMS and advanced technical design makes the plant lower investments, lower consumption, compared to other oxygen system little maintenance, etc characteristics.
2. Simply flow sheet, automatic level, operation easily.
3. Compared to air separation, which needs a small area, a perfect constructor, safe area, it can be used both outdoors and indoors.
4. Operate quickly, Oxygen can be supplied within 5 minutes, shut convenient, can operate easily, the system will control automatically fully, no need for workers on duty.
5. Working under normal temperatures, and lower pressure, the whole recovering process does not need heating, it is safe.
6. The oxygen purity and capacity can adjust easily, strong adaption, oxygen purity (30%-93%), and purity can be controlled, while the oxygen capacity or purity down can greatly save energy.
7. Super filter protective system reduces the pollution for ZMS CMS, advanced molecular sieves compressed technology reduces sieves pulverization, and bed down reduces function.
Product Features
1. Full Automation
All systems are designed for unattended operation and automatic Oxygen demand adjustment.
2. Lower Space Requirement
The design and Instrumentation make the plant size very compact, assembly on skids, prefabricated, and
supplied from the factory.
3. Fast Start-up
The start-up time is about 30 minutes to get the desired Oxygen purity. So these units can be switched ON & OFF
as per Oxygen demand changes.
4. High Reliability
It's very reliable for continuous and steady operation with constant Oxygen purity. Plant availability
time is better than 93% always.
5. Zeolite Molecular Sieves Life
The expected Zeolite Molecular Sieves life is more than 10 years ie the whole lifetime of the Oxygen plant.
So no replacement costs.
6. Low investment and energy consumption
7. Simple operation and maintenance
Application:
1. After the oxygen generator, the oxygen purification system is equipped to guarantee the quality
of the O2 and remove dust, eliminate bacteria, and stabilize pressure to ensure the oxygen
outputted stably and meets medical standards.
2. Users only need to turn the start/stop button to gain oxygen by designing the required flow capacity
and purity within 30 minutes.
3. Single line and double line types are available for option. Users are suggested to choose a single
line type when they only require a stable flow capacity; choose double lines when demand is unstable
and sometimes meet extra peak values.
