Nitrogen Onsite
Nitrogen Onsite
(OP)
I am looking for an onsite system for about 99.5 % purity of nitorgen at 15000 scfh at 90 spig - I am hearing PSA,Membrane and onsite generation - does anyone have any experience in any of these to help me out?





RE: Nitrogen Onsite
The site I work on obtains nitrogen by liquefaction of air. Our provider has 4 compressors two at 60 tonnes/day and two at 80 tonnes/day.
You may want to consider bulk liquid nitrogen delivery as a source? As a back-up,the plant I work on hires a cryogenic storage system that provides nitrogen at 1300kPag (purity 99.9% N2). It has a capacity of 1300Nm3/hr, obviously this can easily be adjusted to suit. Supply of nitrogen in this case is delivered in liquid form via road tankers.
Final I don't have experience with membrane technology

Do a search for N2 membranes, there are many companies which make these packages. Essentially, the more product you take from them, the lower the N2 quality as more and more O2 is left in it. 99.5% is well within the purity limits of membrane technology. I would strongly recommend oil-less compressors to avoid fouling the membranes.
