I am being charged to follow up a project of Instrument air unit.


My question is how to do the preliminary basis of calculations and how to estimate the system capacity? Knowing that this project comes as an extension of an existing gaz treating unit. And since we added new equipment, the old instrument air system is  not enough anymore; so we are installing a new system.


Thank you so much.

many threads discussing this topic, and also Excel pages, see for example
