Industrial Oxygen Removal

Industrial Oxygen Removal

Industrial Oxygen Removal

(OP)
I have a requirement to remove oxygen from an air line. The remaining air will be used to blanket a tank. Is there a device that will remove the oxygen. The tank has to be blanketed and nitrgen is not avalaible.

RE: Industrial Oxygen Removal

How much O2 stream will you make.  Depending on quantity either a polymer membrane air separation unit or a small liquid oxygen distillation plant might be what you need.  If you have a large stream, you could contact the liquid air companies and ask for a proposal for a lease unit, or have them build a unit at your plant.

Also how pure does the nitrogen need to be.  The membrane units tend to leave a fair bit of oxygen in the nitrogen stream and vice versa.

We used to test for purity by blowing the N2 over pure phosphorus.  I don't know if they'd let you do that any more.

RE: Industrial Oxygen Removal

LOL.  So the color of the flame indicates how much oxygen is left?  I'd be surprised if the HSE folks would let that one slide today.

RE: Industrial Oxygen Removal

We used to send it to Carswell AFB for some reason.  Probably to keep the nucs cool???  If it smoked, there was too much O in the N.  It was pretty neat just taking a little chunk of it out and letting air hit it.  It would just smoke for a second then catch fire all by itself as soon as the oil coating evaporated off.  What else did I learn there.  Don't spill liquid O on oil, or try to stop titanium powder from burning by spraying with N2.  I thought that last one was an interesting tidbit.

RE: Industrial Oxygen Removal

we just recommended two different options for something like this PSA or membrane.  If you have large volumes and over 95% N2 purity, PSA is best.
