Question

6.1. Propylene oxide (C,H,O is produced by reacting propylene (C,H) with oxygen and hydrogen. A side reaction resulted 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 (CO, is used as inert solvent) are fed to a continuous reactor. The percent single-pass conversion of limiting reactant is 10%. The fractional yield of C3Hs to C,H,O is 0.80 (i.e., fraction of moles of C,H reacted to produce C,HO. The reactor effluents are separated where gases leave the top of the column. Propylene, propane and propylene oxide (C,H, C,H, and CHOare condensed and removed from the bottom of the column as liquids. Calculate the mole flow rate of each component in the effluent streams. (mm = 12.2 ,no, = 7.19 nN2-27.65, "m =5,000 ) The following reactions are taking place. C,H, + H, +1 / 20,-> C,H,O C,H H2 ->C,H,
