Hi,
PH2S= Yh2S *P total.

Hi Pierre,
I really need your help on this: I calculated the partial pressure of H2S for systems with a gas phase. I now want the calculation for the following:
6-inch flowline
System pressure (Flowing wellhead pressure: 500 Psi)
GOR: 1500 SCF/BBL
Crude oil flowrate: 5,000 barrels per day
H2S content to up to 10% by mole
Regards,

Calc offered by @pierre assumes all 10% (mole) is in the vapor phase.
NACE considers partial pressure of the vapor phase only. Any H2S in the liquid phase is not relevant to vapor phase partial pressure of H2S.
So what is this 10% mole ; vapor phase, or total in liquid + gas ?

Thank you, Pierre.
Hello George,
The mole fraction of H2S in the gas is 10% - this is based on the gas composition / samples.
So, as mentioned above. Multiphase flowline:
6-inch flowline
System pressure (Flowing wellhead pressure: 500 Psi)
GOR: 1500 SCF/BBL
Crude oil flowrate: 5,000 barrels per day
H2S content to up to 10% by mole

1. The service is sour. You will only need calcs to differentiate between any CRAs that are being considered
