PSA Oxygen Generator

Description

PSA O2 Generator Technological Process

There are two adsorption towers loaded with molecular sieve. The clean dry compressed air enters PSA system and the adsorption towers. Compressed air passes through adsorption tower from bottom to top. By principle that molecular sieve has different adsorption to N2 and O2 under different pressure, the N2, H2O and CO2 are adsorbed at surface of molecular sieve, and the unabsorbed O2 is collected as product gas and flow out to the buffering tank from top of adsorption tower. After some time, the adsorbed O2 reaches saturation, and the molecular sieve needs reactivation.After some time, the adsorbed O2 reaches saturation, and the molecular sieve needs reactivation. The reactivation is realized by stopping adsorption step and decreasing pressure in adsorption tower.For saturated adsorption tower, after short time pressure equalization, the pressure shall be decreased to remove adsorbed N2,H2O, CO2, etc. and finish the reactivation process.
The two adsorption tower shall shift for adsorption reactivation to produce oxygen gas at stable flow and purity. The shift iscompleted by automatic control valves under PLC. The performance of PSA plant depends on absorber, carbon molecular sieve,process, equipments structure, and solenoid pneumatic valves, etc. Our PSA plant use PLC of Japan Mitsubishi, molecular sieve specially for PSA oxygen generator, solenoid and pneumatic valve of Germany BURKET.

Oxygen generators are available in 20 standard models with capacity 5-2000 Nm3/h & purity 96%+-3%. PSA generator is designed for 24/7 operation. The touchscreen control has user friendly interface with automatic start/stop function based on gas consumption.

A. Provide maximum commercial value

The filling and compaction of molecular sieve is done in a professional environment in a professional way.

B. The density is greater and the efficiency is higher.

The design of process and structure is optimized, and the system can exert its maximum potential.

C. Higher reliability

Adopt a special valve that is frequently switched over 1 million times without failure to ensure the system's

D. Stable operation

The system design is more reasonable, and the equipment is safer and more reliable.

E. More convenient to use

Nitrogen can be automatically recorded, which is convenient to find the working status at any working time. The system runs fully automatically, and the whole process can be unattended.
