Question
Transcribed Image Text:11.36 It is proposed to produce acetaldehyde by oxidation of ethanol in the gas phase.
C,H,OH(g) + 0,(g) → CH;CHO(g) + H,O(g)
the ratio of air to ethanol in the fresh feed (before it is mixed with recycle stream) is
10 to 1 by mole. The conversion of ethanol on a single pass through the reactor is
25%. The unreacted ethanol is completely separated from the reaction products and
recycled.
(a) What is the ratio of recycle stream to the fresh feed stream?
(b) What is the composition of the outlet stream from the reactor in mass percent and
mole percent?
