Oxygen concentrator - Zeolite

Where are you located? Zeolites are commonly used adsorbants and there are various types available based on requirements. Sodium Zeolite is perhaps the most commonly used adsorbant in chemical industry. Then there are Y zeolites. If I know your location, I can suggest a supplier.

Thanks raotr,

I live in the Midwest, Nebraska to be exact. Any help would be great. When you are working in a budget I like to try and build it myself, if it's possible that is. I can buy commerical units but they are expensive and besides it's always fun to build it yourself and say I did that.

i havent tryed, i found by brousing,just check with them if yes inform me too

if not i will give others but not in your location but in california

sorry

the above said one was a zeolite which belong to agricultural field , which i found after suggesting you

you can ask MR David L.Smith

UOP limited,

PH. (925)648-2060

he is in california.

don't limit yourself to zeolites; look at technology based on activated carbon and new membranes.

Your problem is more is complicated because the oxygen you need must be at enough pressure to push it through the torch. Anaesthetic machines might run at 20 psi but the O2 output is a little over atmospheric pressure just enough for breathing.

I would like to see what others have to say, especially the precise spec of the zeolite and the time cycle of the pressure swing - and is a heater involved.

what rotar said was right,

it is a sodium based zeolite there is also different grade which is lithium based both can be used. But it cannot be Done in a easy manner.

I am an product engineer developing oxygen concentrator.There is a process called PSA pressure swing Adsorption which is implemented to bring the concentration.What concentration do you realy required.What will be the flow Also ??

The Zeolite material comes in different grades. The micropore size of the zeolite particles and the surface area play a very imprtant role in dictating what kind of gases can be trapped. You should experiment with Zeolite/Molecular sieves having 4angstrom units size to start with.

nandakumar - I have seen zeolites used in industrial water treatment systems to remove cations such as sodium, barium and iron, but was not aware of the uses for scrubbing gases. I found a few references on the web to studies about the removal of CO₂ and N₂ from CH_4. In this area those inert gases are removed from the natural gas system through a very expensive cryo process. Is it practical to use molecular sieve like zeolite to accomplish this?

WyoPatriot

Wyo, its economical and a simpler way to scrub the gases using zeolites. Its not uncommon to see the refrigerents cleaning, H2S, N2, CO2 being removed using zeolites. Zeolites are also used to remove aliphatic hydrocarbons from oil streams. Zeolites have multiple uses and one needs to know the exact type and size to get perfect results. Ofcourse, you have to regenerate the zeolites from time to time as the pore space if filled with impurities and the zeolites will lose their adsorption capacity. Any solvents such as Methanol can be sued to regenerate the Zeolites. Zeolites are also used as carriers for catalysts.

If you Google:

"molecular sieve" oxygen enrichment

you will find a number of descriptions of this process. If you Google "oxygen generator" you will find a number of commercially available devices that work on this principle.

Good luck!

Dear waypatriot,

Zeolite is a naturally/manmade mineral group consisting of over 50 different minerals. Made of a special crystalline structure that is porous but remains rigid in the presence of water, zeolites can be adapted for a variety of uses.

• Aquaculture
• Agriculture
• Horticulture
• Water Treatment
• Absorbents for oil and spills
• Gas separations
• etc

There are many process which can be used to generatre N2 Cryogenic,Pressureswing Adsorption Process membrane techonology.But Carbon molecular seives are used to generate N2.

CH₄ can also be seperated by Zeolite but of different grade.

i dont come accross co₂ still.

but i will try give the details in furher posting

Zeolite, the Clinoptilolite type which seems best for your use, can be obtained from the St. Cloud Mining Company of Truth or Consequences, New Mexico, USA. Contact my friend John Bokich at jbokich@stcloudmining.com for further information. He has the product bagged and can provide "clino" in a suitable particle size for your needs.

I am a user of clinoptilolite. More information can be obtained by researching the work of Dr. Mumpton and Dr. Pond of the State University of New York. Also, much information through the International Council on Zeolites.

Hi johnwearusa,

how to join as a member in international council on zeolite i have filled a form in the website but i dont get any conformation.

What kind of material in Clino. Do you manufacture oxygen concentrator.

Hi nandakumar,

Could be that clinoptilolite might not be the absolute best form of zeolite to use in the oxygen concentrator. My work with zeolite has mainly been focused upon the values of a clino attraction to ammonia (NH3). The presence of clinoptilolite in my soil amendment products helps solve damage caused by growers using too much of certain types of fertilizers. Also, the clino is fed as a certain percentage in feed for animals, to prevent toxicity. All this mainly has to do with ion exchange benefits.

The clinoptilolite has a scientific signature like this: (Na K Ca) 2-3 Al3 (Al,Si)2 Si13 O36 with 12 H2O. Mohs scale shows about 4.

Best use, in my opinion, is the application of clino to diet. Nutrient uptake improvements are a matter of record in cattle feeding. Sometimes clino is used in human diet. Clinoptilolite is proving to be a real advantage as an amendment in my compost tea and as an amendment with humus and premium quality composts.

Try communicating with the managers at the St. Cloud Mining Company in Truth or Consequences New Mexico, concerning membership in the International Council on Zeolites. I am not aware of how to proceed beyond the effort you made on their web site.

Thank you for making contact regarding this subject. If I find out more helpful information, I will contact you again. Respectfully, johnwearusa

Thanks for the discussion with me

I know this is a tad late but ill try to add some finality to the thread. After a long while of dinging through data pages and documents related to other gas separators/purifiers i came across the data on a Xenon purifier, to start the process of purifying Xenon you must first remove the Hydrogen, then the oxygen. And after some time sifting through and interpreting data i found the technical specification of the Zeolite used in industrial oxygen purification. *source <Handbook of Zeolite Science and Technology~ Scott M. Auerbach, Kathleen A. Carrado, Prabir K. Dutta>

Zeolite Lix, industrial synthetic Zeolite used since 1997. And after some more time and research, thank you google, i found a supplier.

I would like to see pictures of your Oxygen Concentrator, i'm working on my own but for other reasons. i want to make a lightweight quiet oxygen producer that is small enough to be strapped to your persons during any physically challenging activity as a time to time assist. i was thinking of practical and recreational uses, such as steadying your aim while hunting, physical relief during hiking or long distance sports. And a boost to physical speed and awareness in competitive games such as paintball.
I want to have production at least a liter per min, suitable for about a quarter minuet shot of 80-90% oxygen every 10 minutes or so. I'm unsure of how to get a volume of a gas at specific psi, but i'm thinking 3 liter sized cylinders should be compact enough storage of sufficient oxygen at 60psi. Wish me luck, ill post picture if i ever actually finish it.
