Hi All,

 

I am calculating nitrogen consumption to a feed hopper connected to screw conveyor. Blanketing should be maintained at pressure of 20 mbarg.

 

I couldn't find a reference with detailed explanation and calculation (like API 2000 App. F) for my situation. So, I am considering below assumptions:

 

1. since the hopper contains solid and nitrogen, I assume thermal expansion/contraction is negligible;

 

2. Outflow (volumetric flow) should be replaced by 20 mbarg Nitrogen.

 

So, I am considering the Nitrogen consumption (act.m³/hr) will be equal to volumetric outflow.

 

I appreciate your comment.

 

Regards,
