Question

n-butane burns with 15% excess air, both streams enter at 25 ° C. The gas burns completely producing 90 mol of CO2 / 10mol of CO. The combustion gas comes out at 400ºC and 1 atm. Taking as a basis of calculation 1000 moles / h of the gas that feeds the oven:
1. Draw the process diagram
2. Calculate the air feed rate and the composition of the flue gases.
3. Fill the enthalpy table in / out of the process. Clearly specify the reference status.
4. Calculate the amount of heat given up in the reactor (kW).
