$100\mathrm{.}0$ kmol$/$h of a $60\mathrm{.}0$ mol$\%$ methanol and $40\mathrm{.}0$ mol$\%$ water feed at $40\backslash$deg C is distilled in a column that does not have a reboiler but uses open steam for heating $($see figure in Problem $3.$D$2).$ The column is at $1\mathrm{.}0$ alm. The steam is pure water vapor $(=0)$ and is a salurated vapor. The distillate product is $99\mathrm{.}0$ mol$\%$ methanol and is a saluraled liquid. The hollors is $2\mathrm{.}0$ mol$\%$ methanol and, since it leaves an equibrum slage, must be a saturated liquid. The oolumn is adiabalic and has a lolal condenser.
