For an atmospheric pressure continuous distillation of $1$kmol$\frac{e}{h}r$ of the saturared liquid binary feed with $50$ mole $\%$ composition of the components, and to obtain $90$ mole $\%$ of more volatile component in distillate and $15$mole$\%$ of more volatile component in bottoms, determine:

$($a$)$ Minimum and actual reflux ratio

$($b$)$ Vapour and liquid flow rate in the rectifying and stripping section

$($c$)$ Consider latent heat of the components as $35k\frac{J}{m}ol$; find the amount of steam and cooling water required for the separation

$($d$)$ Number of equilibrium stages needed
