Question: an equimolar mixture of benzene and toluene is fed into...

Question details

An equimolar mixture of benzene and toluene is fed into a distillation tower with a flow rate of 150 mol/s. The vapor leaving the top of the column (stream A) contains 95% benzene The stream leaving the condenser is fed to a valve, and 1/3 of this stream is returned to the column (stream B) and the remainder is withdrawn as the distillate stream (stream C). The distillate stream (stream C) contains 80% of the benzene that is fed to the column in stream F The liquid stream leaving the bottom of the tower (stream D) is fed to a reboiler, where 40% of the reboiler feed is vaporized and recycled to the column (Stream E), while the other 60% is withdrawn as the bottoms product (Stream G). The ratio of the mole fraction of benzene in the vapor stream E to that in stream G is given is 1 Calculate the following; show all your work on the next page Stream A: molar flow rate: .50 mole/s Stream B: molar flow rate: mole/s Stream C: molar flow rate Stream D: molar flow rate: mole/s mole/s; mole/s; mole/s; mole fraction of benzene: Stream E: molar flow rate: mole fraction of benzene: Stream G: molar flow rate: mole fraction of benzene: When writing equations, identify the unit operation, and species that is being balanced, or the name of the type of equation. a) Completely laboia
