3. A process stream of 100 mol/s of n-Hexane vapor at 70.0 °C and 1 atm is fed into a furnace along with a process stream of 50.0% excess dry air (20% O2, 80% N2) at 70 °C and 1 atm. In the furnace, all the hexane is consumed, and the production rate of 60 mol/s CO is obtained. The reaction schemes for complete and incomplete combustion of n- hexane are given as: (1) C6H14 (9) + 5.02(g) – 6CO2(g)...
Question 5 Calcium oxide (Lime) is usually produced by heating and decomposing limestone (CaCO3), cheap and abundant mineral, in a process: CaCO3 (s)CaO (s) CO2 (g) a) Limestone at 25°C is fed to a continuous calcination reactor. The calcination is complete, and the products leave at 900 °C. Taking 1 metric ton (1000 kg) of limestone as a basis and elemental species [Ca(s), C(s), O2(g)] at 25°C as references for enthalpy calculations prepare and fill in an inlet-outlet enthalpy table...
