Question Statement

A feed of $100$kmo$\frac{l}{h}$ contains $35\%$ mole methanol and the remaining water will be processed in a stripping column. The column has a partial reboiler and $2$ equilibrium stages $($total $3$ equilibrium contacts$).$ If the bottom mole fraction of methanol is desired to be $0\mathrm{.}05.$ The feed is saturated liquid, operating pressure of $1$atm. Estimate distillate mole fraction and calculate flow rate of distillate and bottom product.
