The molal ratio of water to ethylene in total feed input to the reactor = 3/5. Conversion of
ethylene = 5%. Calculate the flow rates of streams F2, P,W and R.
Recycle (R) C2H4
94 wt. % Ethanol
F1 = 224 Ib/hr
6 wt. % water

Reactor
Separator
F2 (Water)
Water (W)
Ans. F1 = 1728 Ib/hr; P= 391.5 Ib/hr; W= 1560.5 Ib/hr and R= 4256 Ib/hr.
