Nitrogen data flow survey

Customer Issue

JWF were asked to help a large chemical manufacturer in Grangemouth understand the Nitrogen usage throughout the site and adjoining customers for an upgrade project. 

Due to changing asset demands and a number of modifications made to the network across the site there was a need for further flow measurement and pressure monitoring to help produce an accurate mass balance.  


Our service engineers carried out a 4 phase flow survey across the refinery site measuring nitrogen flows to various parts.

The dry gas seals on the compressor upgrade will require 568 Nm3/hr of nitrogen for a 6 minute duration. 




The data gathered from the temporary measurements carried out across the site can then determine the available capacity for the compressor seal upgrade project. 

The results have allowed our customer to plan how best to carry out the upgrade.
