In a commercial process, a company is planned to burn propane (C3H8) with excess air in an adiabatic reactor. The adiabatic reactor is insulated with lightweight refractory concretes material that able to withstand temperatures at range between 950 to 1550°C. The combustion equation is stated as follows: C3H8 (g) + 5O2 (g) → 3CO2 (g) + 4H2O (g) As a process engineer, you are required to determine the percentage of excess air required for combustion of 200 mol/hr of propane. The propane and excess air are fed at 25°C and 1 atm. The percentage conversion of propane is 50%. Decide one (1) final adiabatic temperature within the range of temperature which insulated material can withstand in your calculation.

Question
In a commercial process, a company is planned to burn propane (C3H8) with excess air
in an adiabatic reactor. The adiabatic reactor is insulated with lightweight refractory
concretes material that able to withstand temperatures at range between 950 to 1550°C.
The combustion equation is stated as follows:
C3H8 (g) + 5O2 (g) → 3CO2 (g) + 4H2O (g)
As a process engineer, you are required to determine the percentage of excess air
required for combustion of 200 mol/hr of propane. The propane and excess air are fed
at 25°C and 1 atm. The percentage conversion of propane is 50%. Decide one (1) final
adiabatic temperature within the range of temperature which insulated material can
withstand in your calculation.
