Propane was burned in a furnace, the combustion reactions that occurred in the furnace was
C3H8 (g) + O2 (g)  CO2 (g) + H2O (l) H°r = -2220 kJ/mol;

Δ
H
= 81.71 kJ
mol (l, 25°C − g, 1000°C)

Propane was completely burned in the presence of excess air entering at 300 °C and the product gas emerged at 1000°C from the furnace. By assuming 10 mol/s of propane fed at 25 °C to the furnace in presence of 20% excess air, calculate the following [2,2,3]

i. Draw and label a flowchart of this process
ii. Construct a enthalpy table and calculate individual enthalpies for the chemical species involved
iii. How much heat (kW) must be transferred from the reactor to maintain the product temperature at 1000 °C.
