Hello
I'm given a gas at a certain T,P and flowrate in kg-mol/hour
I must convert this to m3/hour
I think :
kgmol/hour * (RT/P) where RT/P = V/n = m3/kmol
would give me the correct units.
Is this correct ? are kmol = kgmol ?
Thanks!

For any ideal gas, 1 kg-mol = 22.414 m3 at 0 °C and 1 atmosphere. Thus:
(Equation 1) m3/hr at 0 °C and 1 atmosphere = (22.414) ( kg-mol/hr )
To convert m3/hr at 0 °C and 1 atmosphere to m3/hr at any other T and P, use:
(Equation 2) P1V1/T1 = P2V2/T2
In using Equation 2, be sure to use absolute pressures and absolute temperatures (°K or °R). In some cases where there is a large difference between conditions 1 and 2, you may need to use compressibility factors (Z) in Equation 2. Thus:
(Equation 3) P1V1/(Z1T1) = P2V2/(Z2T2)
(Equation 1) m3/hr at 0 °C and 1 atmosphere = (22.414) ( kg-mol/hr )
To convert m3/hr at 0 °C and 1 atmosphere to m3/hr at any other T and P, use:
(Equation 2) P1V1/T1 = P2V2/T2
In using Equation 2, be sure to use absolute pressures and absolute temperatures (°K or °R). In some cases where there is a large difference between conditions 1 and 2, you may need to use compressibility factors (Z) in Equation 2. Thus:
(Equation 3) P1V1/(Z1T1) = P2V2/(Z2T2)

Just to add a little to 'are kmol = kgmol'......
That is correct if you are working in SI units - all you are saying is that you are measuring molecular weights in kg/kmol.
You can also find lb-moles.
