Massic fractions

Massic fractions

Massic fractions

(OP)

Hello,
I have a problem to calculate a massic composition:
I have 357.28 kg/h of a gas composed by:
CH4 : 88.1859% (massic)
CO2 : 10.1861%
N2  : 1.6209%
H2O : 0.0042%
H2S : 0.0030%
I will pass my gas in an adsorber (molecular sieve) to reduce elimante HO and reduce CO2 and H2S and I will have:
CO2 : 0.0025%
H2O : 0.2.10-6%
H2S : 2.10-6%
But I want to know what are my new massic fractions. how can I do?

RE: Massic fractions

Multiply all the mass fractions by the total mass flow to find the invididual species' flow rates.  Subtract the removed fractions from the 357.28 kg/h flow as kg/h numbers.  Recalculate the new total mass flow rate, and mass fractions.
