Question: Ethane at 25C and 1.1 atm (abs) flowing at a rate of 100 mol/s is burned with 20% excess oxygen at 175C and 1.1 atm

Ethane at 25°C and 1.1 atm (abs) flowing at a rate of 100 mol/s is burned with 20% excess oxygen at 175°C and 1.1 atm (abs). The combustion products leave the furnace at 800°C and 1 atm.

(a) What is the volumetric flow rate of oxygen (L/s) fed to the furnace?

(b) What should the volumetric flow rate of the combustion products be? State all assumptions you make.

(c) The volumetric flow rate of the combustion products is measured and found to be different from the value calculated in Part (b). Assuming that no mistakes were made in the calculation, what could be going on that could lead to the discrepancy? Consider assumptions made in the calculations and things that can go wrong in a real system.
