The distillation column in the UTC chemical engineering and controls systems

laboratory is being used to separate methanol from water. An equimolar feed is fed to

the distillation column at a volumetric flow rate of $3,125\frac{L}{m}in.$ The flow rate of the

bottoms stream is measured and found to be $67\mathrm{.}5$kmo$\frac{l}{m}in,$ and the overhead stream

is analyzed and found to contain $96$mol$\%$ methanol.

The specific gravity of the feed is $0\mathrm{.}8.$ The molecular weight of the feed is $25\frac{g}{m}ol.$

a$.$ Draw and label a flowchart of the process and do a degrees$-$of$-$freedom analysis.

b$.$ Calculate the total molar flow rate $(kmo\frac{l}{m}in)$ of the feed.

c$.$ Determine the molar flow rate of the overhead stream $($ kmo$\frac{l}{m}in$ and the

composition of the bottoms stream $($ mol$\%).$

d$.$ Check your work.
