Partial pressure calculation 2

[IngGasP]

Hi!

I a have hydrocarbon gas mixture whose total pressure is Pt(measured by gage)over 40Barg. Is it correct for computing the partial pressure of components by using this formula: Pi(partial pressure of one component), Yi(molar fraction)

Pi= Yi * Pt

Thanks

Stick to one forum please. You have asked this in Chemical Engineering other topics, and possibly other locations too.

theoretically, it is correct.

When applying Dalton's law, use absolute pressures.

Partial pressures for real gases are estimated using compressibility factors as, for example, in:
