Project/Category | Cryogenic air separation oxygen generator | QVO Vacuum pressure swing adsorption (Vpsa) oxygen generator |
Separation principle | Make the air liquefacted, according to different oxygen and nitrogen boiling point to achieve separation | Pressure adsorption and vacuum desorption, separating the oxygen and nitrogen of different adsorption capacity |
Process characteristics | Process complex which need compression, cooling, pretreatment, expansion, liquefaction, shunt, etc., the operating temperature is below -180ºC |
The technological process is simple, the operation temperature is normal temperature |
Device characteristics | More moving parts, more complicated structure, more equipment control element |
Few movement part, simple equipment, less control element |
Operating characteristics | Complex operation, cannot use immediately | Easy operation.Operation control and monitor all realized by PLC;Starting and stopping time is short, less than 5 minutes;No need for regular overhaul and maintenance;Operator could work after a short time training |
Using range | Need a variety of oxygen, nitrogen and argon gas; Oxygen purity is more than 95% | Extracting a single gas, purity between 90%-95% |
Maintenance characteristics | Because of the high precision and requirement, centrifugal air compressor, condensing steam engine and expander must equipped with trained maintenance personnel | Blower, vacuum pump, all belong to normal maintenance can be performed by ordinary maintenance personnel |
Installation characteristics | Complex unit installed, covers big area, long cycle, high cost |
Small unit shape, cover small area, conventional installation, short installation period, low cost |
Automatic program safety | Easily broken and affect the normal operation of equipment | After startup can run fully automatic;All safety factors, without the possibility of an explosion |
Purity adjustment | Purity adjustment is not convenient, cost is high |
Simple purity adjustment and low cost to generate oxygen |
Oxygen generating cost | energy consumption:>1.25kwh/m3 | Energy consumption:<0.35kwh/m3 |
Total investment | High costs | Low cost |
