Technology brief:
There has been a growing demand for small and medium-sized oxygen
equipment with rapid development of the national economy in recent
years. Beijing Peking University Pioneer Technology Co., Ltd.
(hereinafter referred to as PIONEER), seizing this market
opportunity with its advanced technology and engineering experience
of more than **0 sets of oxygen equipment, has produced the
customized the new skid-mounted PSA oxygen equipment through its
continuous development and innovation. The PSA-O2 generator meets a
wide range of requirements for users in need of small and
medium-sized oxygen equipment. It has remarkable advantages on its
stability, simplicity, efficiency and energy saving.
Production Capacity
*0Nm3/h***0Nm3/h, equivalent to liquid oxygen of about 1.7 TPD *5.4
TPD.
Typical Applications
The PSA-O2 generator is widely used in water treatment, flue gas
ozone denitrification, kiln combustion, pulp bleaching,
aquaculture, medical and other fields...
Technical Advantages
1. Advanced single-vessel process
Compared with the traditional double-vessel process, the
world-leading single-vessel process requires less equipment but
brings more stable performance with easier operation and
maintenance.
2. High efficiency lithium-based molecular sieve
The third generation of high-efficiency lithium-based oxygen
generation molecular sieve (PU*8) has a lithium ion exchange rate
of over *9%, bringing plenty of advantages such as high strength,
high nitrogen and oxygen selectivity, large bulk density, uniform
particles, long service life, etc. In combination with the
proprietary automatic filling technology, the stability of the
molecular sieve bed is effectively guaranteed.
3. Special valves for oxygen generation
Special valves for oxygen generation are more suitable for VPSA
oxygen process, offering good sealing, fast switching speed, stable
performance and other characteristics, along with outstanding low
failure rate and easy maintenance.
4. Modular integrated design
Compared with the conventional double-vessel process, the equipment
is more compact and the plot area can be reduced by more than
*0%.
5. Low operation cost
The power consumption of oxygen is as low as 0.*5kWh/Nm3, the
annual maintenance cost is *0% lower than that of a common PSA
oxygen generator. The annual comprehensive operation cost is also
reduced by more than *0%, compared with the cost of common PSA
oxygen generator or purchasing liquid oxygen.
Technical Principle
TAdsorption process: the pressurized ambient air is passed through
the adsorption vessel, where the impurity gases (i.e. predominantly
nitrogen) are preferentially adsorbed by the molecular sieve.
Oxygen is enriched at the top of the adsorption vessel, then enters
an oxygen buffer tank to supply oxygen to the downstream;
Desorption process: after the molecular sieve is saturated by
adsorption, the valve is switched to allow the blower to reverse
act and vacuumize, thus restoring the adsorption capacity of the
molecular sieve. In this stage, oxygen is continuously supplied to
the downstream from the oxygen buffer tank.
