I need to calculate the amount of N2 required (in NM3) and time required to fill a vessel of 80 M3 (from zero pressure to 3.5 barg).

This is required for purging operation. Pressurization will be carried out through 1'' utility header supply fitted with globe valve.

N2 is available in the plant utility station at 6.5 barg pressure.

Appreciate your kind help.

A.BHANU:

 

I believe the excellent document Breizh has furnished clearly explains how to estimate the N2 amount needed for purging a vessel.

 

Have you read the document?
