CE Compliant PSA Oxygen Gas Generator
Description
CE Compliant PSA Oxygen Gas Generator, uses clean compressed air as raw material and zeolite molecular sieve (ZMS) as sorbent, to produce oxygen gas with Pressure Swing Adsorption (PSA) technology in normal temperature. Comparing with oxygen, nitrogen is preferentially adsorbed by ZMS while at high pressure. ZMS releases adsorbed nitrogen at low pressure, which is called regeneration. The oil-free and dust free compressed air enters one of the two adsorption towers filled with ZMS. Nitrogen is adsorbed ZMS micro pores and then retained and leaves oxygen as product gas. When ZMS in one tower is saturated with nitrogen, the adsorption tower is depressurized and ZMS is regenerated for next cycle. While one tower finishes the cycle, the other adsorption tower starts to work. With control on/off state of the pneumatic valve by PLC, to separate nitrogen and oxygen gas, and create continuous flow of oxygen with required purity.
Features
1. Full Automation
All systems are designed for un-attended operation and automatic Oxygen demand adjustment.
2. Lower Space Requirement
The design and Instrumentation makes the plant size very compact, assembly on skids, prefabricated and supplied from factory.
3. Fast Start-up
Start-up time is about 30 minutes to get 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
Expected Zeolite Molecular Sieves life is more than 10-years i.e. whole life time of Oxygen plant. So no replacement costs.
6. Low investment and energy consumption
7. Simple operation and maintenance
