Principle of PSA Medical Oxygen Generator

PSA oxygen generator uses clean compressed air as raw material and zeolite molecular sieve (ZMS) as adsorbent, to produce oxygen gas with Pressure Swing Adsorption (PSA) technology in normal temperature. ZMS is round granular adsorbent full of micro pores inside and outside, which has characteristic of selective adsorption. N2 has higher diffusion rate while O2 has lower, therefore N2 is adsorbed into ZMS while O2 is out of it. With controlling on/off state of the pneumatic valves by PLC, adsorbing under pressure and regenerating without pressure, to separate nitrogen and oxygen gas, and create continuous flow of oxygen with require purity.

Oxygen Generator for Medical Application

There is one percent (1%) argon and twenty one (21%) percent oxygen in the air. It is hard to remove argon from argon/oxygen mixture with nowadays PSA technology. In theory, the upper limit of oxygen purity is 95.45%. Due to PSA technology and ZMS performance, it is stable and economical to run at purity of 93% with fluctuations. So in PSA oxygen generation industry, the 93±3% is a worldwide acknowledged standard. Actually it can reach 95% or can be a little higher but is not stable. And it is absolutely not economical to run the system at 95%. So PSA oxygen generator manufacturers claim 93±3% purity in general, which means lower limit is 90%. For medical use, the lower limit 90% is a compulsory and makes sense. It is not a compulsory for 95% or 96% purity. On the contrary, 96% is an upper limit that means the oxygen purity should not be higher.

There are standards mentioning 99.5% purity oxygen for medical use, which is based on cryogenic technology but not PSA. Cryogenic oxygen contains certain quantity of halogen which is harmful to humans. But there is no such contaminant in PSA oxygen. So the 99.5% is a minimum requirement for cryogenic oxygen purity but not PSA. United States Pharmacopoeia (USP) Oxygen 93% Monograph has specifications as “not less than 90.0% and not more than 96.0%” for PSA oxygen.

It is not necessary for humans to breathe 100% oxygen. For metabolism, oxygen is a must. It is harmful and even fatal to live in hypoxia condition. However, it is also dangerous for human to breathe pure oxygen for long period for it will cause oxygen poisoning. Possible symptoms of the illness are as follows:

Irritability, confusion or anxiety
Tingling or numbness of the mouth
Coughing
Nausea, vomiting,
Tinnitus
Dizziness
Blurred vision and/or tunnel vision
Muscle twitches, especially the face
Pneumonia,
Scarring and bleeding of the lungs
Seizures

So it is apparent that higher oxygen purity does not always mean better.
