Mass Transfer - Engineering
Q1: According to the Fenske equation, what will be the minimum number of plates required in a distillation column to separate an equimolar binary mixture of components A and B into an overhead fraction containing 99 mol% A and a bottom fraction containing 98 mol% B ? Assume that relative volatility (αAB = 2) does not change appreciably in the coloumn.A 5
B 9
C 12
D 28
ANS:C - 12 The Fenske equation is used to calculate the minimum number of theoretical plates required to achieve a specified separation in a distillation column. It is given by: 𝑁𝑚𝑖𝑛=log(𝐷𝐵⋅𝑌𝐷𝑋𝐷)log(𝛼−1)Nmin=log(α−1)log(BD⋅XDYD) Where:
