Good evening all,
we have propylene and Ethylene refrigeration systems in our unit. Those are 3 stage centrifugal compressors. 8900KW and 4084 KW respectively. Both are motor driven.
We are in Erection stage. During the time of Mechanical run test, can we run these compressors with Nitrogen for performance verification?
My understanding is that, the volumetric flow will be the same as other gas, but Mass will be different because of the nitrogen's density. It may not be a problem since N2 is not heavier than the Propylene/ Ethylene. But any otherthings should be considered?
Surely, we will be having the vendor(Manufacturer) at site during the time of Trial run, They will give us the correct guidelines. But I wish to ask here, So I can get anyone experienced personnel's view regarding this.
