ropylene oxide (C3H8O) is produced by reacting propylene (C3H6) with oxygen and hydrogen. A side reaction results in reacting propylene with hydrogen and produces propane. A mixture of 35 mol/h air, 4 mol/h propylene, and 12.6 mol/h hydrogen (H2) along with 5000 mol/h carbon dioxide (CO2 is used as inert solvent) is fed to a continuous reactor. The percent single-pass conversion of limiting reactant is 10%. The fractional yield of C3H6 to C3H8O is 0.80 (i.e., fraction of moles of C3H6 reacted to produce C3H8O). The reactor effluents are separated where gases leave the top of the column. Propylene, propane, and propylene oxide (C3H6, C3H8, and C3H8O) are condensed and removed from the bottom of the column as liquids. Calculate the mole flow rate of each component in the effluent streams. (n H2 = 12.2, n O2 = 701. 9, n N2 = 27.65, n CO2 = 5000) The following reactions are taking place:
