1. A liquid mixture that contains 55 kmol% acetone (CH3COCH3), 23 kmol% acetic acid (CH;COOH), and the balance, acetic anhydride [(CH,CO),0] is distillated at 101 32 kPa. The acetone enters the distillation column at a rate of 5 000 kg/hr. The overhead product is essentially pure acetone. The bottom product contains the remaining liquid mixture and .5% of the acetone in the feed is recovered in this stream. a) Sketch and label a flow chart of the process (properly labeling all streams and species within those streams). b) Perform degree of freedom analysis for the process. c) Calculate the molar flow rate of the feed solution in kmol/hr.

Question
![1. A liquid mixture that contains 55 kmol% acetone (CH3COCH3), 23 kmol% acetic acid
(CH;COOH), and the balance, acetic anhydride [(CH,CO).O] is distillated at 101.32 kPa. The
acetone enters the distillation column at a rate of 5 000 kg/hr. The overhead product is
essentially pure acetone. The bottom product contains the remaining liquid mixture and I.5%
of the acetone in the feed is recovered in this stream.
a) Sketch and label a flow chart of the process (properly labeling all streams and species within
those streams).
b) Perform degree of freedom analysis for the process.
c) Calculate the molar flow rate of the feed solution in kmol/hr.
d) Determine the molar flow rate and molar composition of the product streams.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F94ff44da-c28c-4877-bad0-653ae9a30c12%2Fc44793bb-e8a9-468d-8051-da0cab29e42f%2Fo69036c_processed.jpeg&w=3840&q=75)
