## Question:

Repeat the calculations of Example 6.3, but for \(80 \mathrm{~mol} \%\) of the liquid distilled.

**Data From Example 6.3:-**

Suppose the liquid of Example 6.1 [50 mol% n-heptane (A), 50 mol% n-octane (B)] were subjected to a batch distillation at atmospheric pressure, with 60 mol% of the iquid distilled. Compute the composition of the composited distillate and the residue.

**Data From Example 6.1:-**

A liquid mixture containing 50 mol% n-heptane (A), 50 mol% n-octane (B), at 303 K, is to be continuously flash-vaporized at a pressure of 1 atm to vaporize 60 mol% of the feed. What will be the composition of the vapor and liquid and the temperature in the separator if it behaves as an ideal stage? Calculate the amount of heat to be added per mole of feed. n-Heptane and n-octane form ideal solutions.
