Bình LPG:

`n_{C_3H_8}={12}/{2.44+3.58}.2={12}/{131}(kmol)={12000}/{131}(mol)`

`n_{C_4H_{10}}={12000}/{131}.3/2={18000}/{131}(mol)`

`->Q_{toa}={18000}/{131}.2850+{12000}/{131}.2220=594961,8(kJ)`

Bình biogas:

`n_{CH_4}={594961,8}/{890}=668,5(mol)`

`n_{gas}={668,5}/{60\%}=1114,17(mol)`

`V_{gas}=1114,17.24,79=27620,27(L)`
