Hallo

I have another question:

 I need to calculate how many of gases (m3/hr) we recive from burning:

450 000 Nm3/hr

 

H2  [mol/ mol]  3,064

CO  24,296

CH4  0,035

C2H4  0,000

C2H6  0,000

C3H6  0,000

C2H2  0,000

CO2  17,768

N2  53,874

O2  0,963

Suma mol/ mol100,0

 

 

I have done this with two ways:

1) V=0,210*(Q/1000) - This is a theoretical equation  and I received

 

Nm³/h

2 266 081

 

 

2) Vos=Vco2+Vso2+Vh2o+Vn2

Vco2=CO2+CO+CH4+2C2H2+2C2H4

Vh20=H20+H2+cCH4+2C2H4+C2H2

VN2=N2+0,79*(1/21(H2/2+CO/2+2CH4+2C2H4-O2)


and i received

     1 206 678   

 

 

And mine question is why there is so much different? In publication which I have used this equation there is not so much problem, could someone give my some advice form where (publication) I can find some good information about it or a little help which this.

Like all good chemical engineers you should do a heat and material balance.
