A liquid solution initially containing 60% by mol of acetone and 40% by mol of water was differentially distilled (single distillation, Rayleigh), vaporizing 30% (mol) of the feed. The following table presents the thermodynamic equilibrium data for the mixture at the pressure at which the column operated (about 1 atm). A) If 100 kg-mol total are fed at the beginning of the process, what will be the production of distillate in number of moles? B) What is the composition of the accumulated distillate (answer is 0.857)? C) What would be the recovery of the most volatile in the distillate?

A) If 100 kg-mol total are fed at the beginning of the process, what will be the production of distillate in number of moles?
B) What is the composition of the accumulated distillate (answer is 0.857)?
C) What would be the recovery of the most volatile in the distillate?
D) If we decided to proceed with the distillation until the temperature of 64ºC, how much do you estimate that would be left in moles in the base (“still pot”)? What would be the composition of the accumulated distillate and
how much would be the recovery of the most volatile?
