A fuel stream with a total molar flow rate of 100 mol/s is composed of 40% methane and the remainder propane (molar basis). It is fed to a combustion unit with 20% excess air. a) Sketch the process, labeling each stream. b) Assuming complete combustion, provide balanced reactions for the two reactions, with integer values for the reactants and products. c) Complete the composition table below for complete combustion and 100% conversion of limiting reactants. List all components that are present. Note that there may be more rows than required. Component Nin (mol/s) nout (mol/s) d) How will the molar flow rate of air into the reactor change if the air is fed in at 20% excess and both fuels have a 50% conversion (still complete combustion)? Be quantitative in your answer for full marks. e) Consider a combination of complete combustion and incomplete combustion for both fuels. Write the balanced chemical reactions using integer values for the reactants and products. f) For part e), how will the molar flow rate of air into the reactor change if the air is fed in at 20% excess, both fuels have 50% conversion and there is some incomplete combustion, with a selectivity of CO2:CO equal to 9:1?
