Typical Air Consumption Figures
#1

i) packages (in continuous use)
ii) nitrogen generation package (in frequent use)
Is there any other reference I can use?
Thanks for your help!

Have a look at the following link. If you use the "Search" feature of the forum you will find answers to a lot of queries since a lot of the posts on the forum are of a repetitive nature:

for a nitrogen generator ( N2 # 97%) , I have a proposal where air consumption is 2.85 Nm3 air /Nm3 N2 , let say 3 .
hope this Helps .

However another issue popped up: I now am trying to find a typical air consumption value for system packages, in a previous note, the value provided was 10 Sm3/h, however I couldn't find that value in the references mentioned in that note or any other reference that I have. How does one come up with 10 Sm3/h per system package? Any idea?
@breizh: I'm a bit confused, is Sm3/h different from Nm3/h?

@Ankur: I did use the search function, I found the same thread you posted among others & I couldn't find the answer I needed. But after badgering a senior, I got more information & could estimate the service air consumption for the nitrogen generation package, turned out I didn't have enough information to find that value!

S stands for standard condition ( to be defined , in US60F and 1atm)) and N for normal condition (0C and 1 atm).
For N2 Generator , I'm quite confident with my figures , I had several proposal but it depends of the quality of N2 .

Well attached is a shot of the calculation I did to find out the service air consumed by the generator, assuming 95% membrane efficiency (I got this figure by reading several vendor documents & other sources on the web). I will insert this calculation in my report.

One internet source offers tabulated data for Air feed vs. Nitrogen flows at various recovery (Nitrogen purity) levels: http://www.igs-globa...eron/module.htm
As for the packaged units, it is virtually impossible to supply you with Air consumption/demand figure as it varies upon package size and, of course, the type of packaged unit. Again, contacting different vendors will put you on the right track. I'm sure they are willing to provide you with all the data you need - assuming that you are a serious potential customer of their products.

Yeah I realized that the air consumption is specific to the system package, which is why I'm wondering how the previous report used 10 sm3/h PER package, it wasn't logical & no references listed for that!
