Question
1. 100 kmel mixture containing 35% ethanel (A) and 65% water (B) bx mole; It is heated and evaporated under differential conditions at a pressure
1. 100 kmel mixture containing 35% ethanel (A) and 65% water (B) bx mole; It is heated and evaporated under differential conditions at a pressure of 101.32 kPa until 25 kmol is distilled.
a. Find the composition of the liquid remaining at the end of distillation,
b. Calculate the average composition of distilled steam (distillate)
c. Find the compositions of the bottom and top product when equilibrium distillation (flash) is applied to the same misture to obtain 25 kmel of steam (distillate).
d. Compare the preduct recovery and product purity values obtained by using the differential and flash distillation operations.
