Question $2$

$(max10)$

A saturated liquid feed of $200$ mol$/$h at the boiling point containing $42$mol.$\%$ heptane and $59$mol.$\%$ ettryl benzene is to be fractionated at $101\mathrm{.}32$kPa abs pressure to give a distillate containing $97$mol.$\%$ heptane and a bottom contsining $1\mathrm{.}1$mol.$\%$ heptane. The reflux ratio used is $2\mathrm{.}5$:$1.$ Catculate:

a$)$ The mol$/$h distillate

b$)$ Mal$/$h bottoms

c$)$ Thecretical number of trays

d$)$ And the feed tray number

Equilibrium data are given below an $101\mathrm{.}32$kPa abs pressure for the mole fraction nheptane $x_H$ and $y_N$
