Question

(50%) Pure ethylene (C2H4) and oxygen are fed to a process for the manufacture of ethylene oxide (C2H4O) C2H4 + 1/2 O2 arrowright C2H4O The process flow diagram is shown below. The catalytic reactor operates at 300 degree C and 1.2 atm. Under these conditions, the ethylene conversion per pass is 50% and, of the ethylene consumed, 70% is converted to ethylene oxide. The rest of the ethylene reacts to form CO2 and water vapor (undesired reaction) C2H4 + 3O2 rightarrow 2CO2 + 2H2O For a daily production of 10,000 kg of ethylene oxide: Calculate the m3/h of total gas entering the reactor at STP if the ratio of O2(g) fed to fresh C2R,(g) fed is 3:2. Calculate the recycle ratio in m3 at 10 degree C and 100 kPa of ethylene recycled, per m3 at STP of fresh ethylene fed. Calculate the m3 of the mixture of CO2, O2, and H2O leaving the separator per day at 80 degree C and 100 kPa.
