Problem #$2($Problem solved by:

A feed of ethanol$-$water mixture containing $60w\frac{t}{b}ar\frac{\%}{b}ar\frac{\text{e}\text{t}\text{h}\text{a}\text{n}\text{o}\text{l}}{b}ar\frac{is}{b}ar\frac{to}{b}ar\frac{be\text{d}\text{i}\text{s}\text{t}\text{i}\text{l}\text{l}\text{e}\text{d}to\text{p}\text{r}\text{o}\text{d}\text{u}\text{c}\text{e}}{b}ar($ distillate containing $)$

$95wt\%$ ethanol and a bottoms containing $3wt\%$ ethanol. For a feed of $30,000$ kg$/$h and at conditions such

that it is $50\%$ liquid and $50\%$ vapor when it enters the tower, determine the molar flow rates of the distillate

and bottoms. Determine the minimum reflux ratio and the number of theoretical stages for $R=2\mathrm{.}0R_m.$

What is the feed plate number? Determine also the minimum number of plates. You will need first to

generate equilibrium data for a column operating between $78\mathrm{.}2$degC and $100$degC.
