One thousand kilograms per hour of a mixture containing equal parts by mass of methanol and water is distilled. Product streams leave the top and the bottom of the distillation column. The flow rate of the bottom stream is measured and found to be 823 kg/h, and the overhead stream is analyzed and found to contain 85 wt% methanol. (a) Draw and label a flowchart of the process. (b) Calculate the mass and mole fractions of methanol and the molar flow rates of methanol and water in the bottom product stream.

Question
Transcribed Image Text:One thousand kilograms per hour of a mixture containing equal parts by mass of methanol
and water is distilled. Product streams leave the top and the bottom of the distillation column. The flow
rate of the bottom stream is measured and found to be 823 kg/h, and the overhead stream is analyzed
and found to contain 85 wt% methanol.
(a) Draw and label a flowchart of the process.
(b) Calculate the mass and mole fractions of methanol and the molar flow rates of methanol and water
in the bottom product stream.
