[labnetwork] Is Nitrogen Generator a Viable Option

[John Boyle]

I worked in the industrial gas industry for 25 years and Nitrogen generators
are a reliable source of nitrogen for many customers. Usually Nitrogen
generators can provide a range of purity suitable for most industrial
applications..the purity usually is higher when the unit is operated at
lower flow and purity is lower at higher flow rates. For UHP applications
you would likely need an add on purifier to remove O2, H20. If your UHP
process is sensitive to other contaminants (CO,CO2, THC) there are some
purifiers to remove these as well. There are two main types to
consider----membrane based units and adsorbent bed units. 

 

A Nitrogen generator will not provide Liquid N2 and so any operations that
require cryogenic temperatures that LIN provides would not be amenable to
generated N2.

We have N2 supply via a generator. We supply both High purity and Ultra High
purity N2 to our labs. The installation of an N2 generator will greatly
reduce you LN2 cost but will have a large upfront cost as we have 2 N2
delivery(hard piping) structures in place. I would have to go through some
historical data that is decades old to get you numbers but a it all depends
on use. Best guess is a couple years out on ROI but it is a no brainer if
you are a heavy N2 user.

Greetings to All,

I am writing because we are being challenged, like everyone, to reduce our
cost for research. We are considering other options for our Nitrogen gas
source including a Nitrogen generator due to the recent cost increase of
LN2. We are currently using a 2-tank system which supplies both the liquid
and gaseous nitrogen to our facility.

We are averaging 80 to 90 SCFM of utility nitrogen and 6 -7 SCFM of High
Purity Nitrogen. We would continue to maintain our liquid nitrogen supply.

 

Please provide your positive and negative experiences with Nitrogen
generators as well as the manufacturer of the unit. All comments/suggestions
are welcomed.  Thanks in advance for your input.

 

 

Best Regards,

Rich Harlan
