I have a question. PSA is dirven at high pressure, but VSA is driven at atmosperic pressure. Is there a difference in adsorption power? If it has difference, how much is it?
Great question! The molecular sieves, or zeolites, used in PSA and VPSA processes are not the same. In PSA, the zeolites used are inexpensive and have a lower nitrogen adsorption capacity at normal atmospheric pressure. That's why you need a higher pressure (around 50-90 psig) in order to increase their adsorption capabilities. VPSA uses specialized zeolite which has a higher nitrogen adsorption at near atmospheric pressure. When comparing the two zeolites, you'll get the same results showing when the common zeolite in PSA is at high pressure while the specialized zeolite in VPSA is at normal atmospheric pressure. As such, VPSA is more energy efficient to operate because no high-pressure compression is required. I hope this helps!

I want to build a small portable oxygen concentrator for my family member . Does this technology helps? can you help me with that
I recommend you follow @oxygenalliance
awesome. Excuse me can we use the same technology for carbon capture too?
Yes and no. With my understanding, the trouble is that while it is possible, it can be incredibly expensive.
Thanks ... excellent and very informative video
Thanks for the feedback! :)
Wow ❤️❤️, beautiful video. Can I get more information
Absolutely! What information were you looking for?
Very Informative
Thank you!
Thanks for watching!
Thank you ...this helped me alot
How it is not required to remove moisture from Air & Oxygen in VSA system...!??
Good explanation
Thank you!

You mean for VSA not for VPSA in above reply....??
