Question

A fuel gas that contains
40.00
mole% methane and the balance ethane is burned completely with pure oxygen at °C, and the products are cooled to °C.

suppose that the combustion takes place in a constant-volume batch reactor. Take mol as a basis of calculation of the fuel gas charged into the reactor and assume any percent excess oxygen,

and calculate –Q(kJ) for the cases of liquid water as well as water vapor as products.

Answer 1

so the steam required 5.875 15 kg/h Solution (Assuming 0% of us cuygos) (being of Rendron Equellons exers of oxygen CHA + 202 coat & H₂O methan Co Hot 7 ethane 200g + 3 H₂O Methane HHV LHV For the case of liquid water heat of combustion - highe heating value 889 KI/mol For the care of water vapone head of umbustion loured healing value 800k/ml Elhane For the case of liquid wala heat of connection highie heating valere 1560 kil mal For the of wate Vapoue heat of combustion lower heating value LHV 1428.6 kJ/mol i Case of liquid waled as part Q-hant combustion 0.44 HAU methane + 0.6 kHVE Ethane - 0.4 x 889 KT) mil + 8 6 1560 kJ/mol HHV
