e) The%conversionofO2?

Q2: Ethylene oxide (C2H4O) is formed by the partial oxidation of ethylene (C2H4) in a gas phase reaction over a silver catalyst according to the stoichiometry: 2C¿H4 + O2 –→ 2C¿H4O In this process 1000 mol/h of pure ethylene (C¿H4) is fed to a reactor along with an air stream (21 mol% O2, 79 mol% N2). The effluent stream contains 300 mol/hr of ethylene oxide (C2H4O). The ethylene oxide (C2H4O) is also 16.7 mol% of the effluent stream. Determine the full composition of the effluent stream? Feed Effluent REACTOR Q3: To save energy, stack gas from a furnace is used to dry rice at a feed rate of 1000 kg/hr. The flow sheet and known data are shown below. Determine all unknown rates and composition of streams. Recycle Gas, R: Kg/hr Wet Stack Gas, N : Kg/hr G:0.9069 gm Gas/gm W: 0.0931 gm Water/gm G: gm Gas/gm gm Water/gm W: Stack Gas, S: Kg/hr Mixed Gas, M : Kg/hr G :0.9527 gm Gas/gm W: 0.0473 gm Water/gm G : 0.948 gm Gas/gm W: 0.052 gm Water/gm DRYER Wet Rice Feed, F: 1000 kg/hr Dry Rice Product, P: kg/hr R: 0.75 gm Rice/gm W : 0.25 gm Water/gm R: 0.95 gm Rice/gm W : 0.05 gm Water/gm
