100 mol of oxalic acid (H2C2O4) is burned (95% conversion) at
atmospheric pressure and 99 °C with 10 % excess air so that the
selectivity of CO2 relative to CO is 4. The chemical reaction
equations for the combustion of oxalic acid are given as: Reaction
1 (desired): ??2??2??4+1 2??2→2????2+??2?? Reaction 2 (undesired):
??2??2??4→2????+1 2??2+??2??
a) Draw and completely label a flowsheet of this process, clearly
assigning variable names to all known and unknown quantities. (6
pts) b) What are the molar flow rates of all species leaving the
combustion chamber? (20 pts) c) What is the yield of CO2? (6
pts)
For parts d), e) and f), assume water is the only species that can
condense and if you cannot solve for the molar flow rates of the
product gas, assume equimolar compositions of the six product gas
species.
d) What is the relative humidity of the product gas? (4 pts) e)
What is the dew-point pressure of the product gas? (6 pts) f) What
is the dew-point temperature of the product gas, to the nearest 1
°C? (6 pts
