API RP 14E

(OP)

DEAR ENGINEERS,

I NEED ASSISTANCE IN ESTIMATING THE VAPOUR PRESSURE OF CRUDE IN MY NPSH(AVAILABLE) CALCULATIONS.

RE: API RP 14E

Can vary hugely depending on what processing has taken place upstream. Your boiling point could be anything from sub zero C to over 100C. How are we going to know??

This needs specific info from your client / operator / process engineer.

My motto: Learn something new every day

Also: There's usually a good reason why everyone does it that way

RE: API RP 14E

Your supplier should know but try 10 psi, 12 if you think the crude may be very light

RE: API RP 14E

But at what temperature? This is very often critical in Hydrocarbon fluids. VP/NPSH could be OK at 15C, not OK at 30C

My motto: Learn something new every day

Also: There's usually a good reason why everyone does it that way
