A 6 0 : 4 0 liquid mixture of ethanol and water is fed to a distillation column which produces both a liquid and vapor

A 60:40 liquid mixture of ethanol and water is fed to a distillation column which produces both a liquid and vapor stream. The vapor leaves the top of the distillation column where it is completely condensed and split into two equal fractions. One fraction is taken off as a product stream and the other is fed back to the column. The liquid leaving the bottom of the column is fed to a partial reboiler in which 40% of its vaporized. The vapor from the reboiler is recycled back to the distillation tower and the liquid is taken off as bottoms product. The partial reboiler is at 500mm Hg and 90C. We have inlet feed rate mixture of 20kg/h
80% of the ethanol fed to the column leaves the condenser in the product stream. Perform mass balance and energy balance.
