I would appreciate if anyone can help me to find how I can go from fraction mol to fraction volume, because I only have already found the convertion from fraction mol to fraction weigth and viceversa.

you can convert a component i in a mixture from mole fraction to volume fraction

xvi = zi * xmi / SUM(zi*xmi)

where zi is the compressibility factor of component i

of course for SUM(xmi) = 1

SUM(zi*xmi) = Zmix

and at low pressure and temperature you can assume Z = 1.0 which means that for ideal gas mole fraction = volume fraction
however that is not true for real gas,
you can calculate compressibility factors or derivatives of volume vs. composition (which gives equivalent results) with a software like Prode Properties (see prode.com) or follow this thread

Dear Carlo

This formula that you mention result very useful, please could you give me the bibliography where I can found the formula. Of course if can you recommend me another bibliography for natural gas would be great.

Thanks best regards

jorge,
the above is the same to

Vmix = SUM(Vi)

where Vi is the volume fraction of component i
which is basic thermodynamics.
As said you can calculate the different volume fractions with a EOS (for example Soave-Redlich-Kwong or Peng-Robinson) or another accurate correlation,
you may need the derivatives of volume vs. compositions to calculate the different volume fractions,
different derivatives (vs. composition, temperature, pressure) are available in Prode Properties (see 'www.prode.com') or other tools that integrate directly with Microsoft Excel.

I might acknowledge if anybody can help me to find how I can head off from part mol to division volume, since I just have recently discovered the convertion from portion mol to portion weigth and viceversa.
