Partial pressure of hydrogen

An methanol (CH3OH) converter has the following operating conditions:
Pressure: 105 bar (g)
Temperature: 270°C

The gas mixture composition is:
CH4 = 12 vol %
CO = 0,74 Vol %
CO2 = 1,41 vol %
H2 = 80,33 vol %
Methanol gaseous +/- 5 vol%
N2 = 1,0 Vol%

Total 100,48 vol %

Can someone give me the partial pressure of the Hydrogen?

Regards,

Bas

I pride myself on never having used an exclamation point in technical writing (except as a direct quote of someone who uses them). I have a really hard time focusing on a post that uses that punctuation in the subject line.

Without relative percentages of the components, the answer to your question is "no". No one can give you the partial pressure of Hydrogen.

Dear David,

I updated the topic. Maybe you can answer it now.

Thanks in advance,

Having pressure and temperature helps, but again without the relative proportions, no,

I have updated the topic again, now with the relative proportions.

Hopefully someone can give me the partial pressure of the hydrogen.


Thanks in advance.
 
I think Wikipedia gives you all you need.

Vx/Vtotal = px/ptotal or 80.33/100.48 = pH2/106

Use absolute pressures with partial pressures.

Good luck,
