In the countercurrent distillation of Benzene-Butane binary system, vapor and liquid phases involve both components together. Latent heat of benzene for vaporization is approximately equal to 1.6 times of butane's latent heat of vaporization. The rate of liquid flow getting into the tower from the top is L₂ = 100 kmole/hour and xA₂ = 0. Rate of vapor flow getting into the tower from the bottom is V₁ = 100 kmole/hour and y_A1 = 0.50. It is required for the vapor phase concentration to be reduced to y_A2 = 0.10 value at the end of the operation. According to this data;

a) Determine which component is benzene, which is butane of A and B components.

b) Find the relationship between N_A and N_B.

c) Write down the mole fractions of the components for the top and bottom points of the column.

d) In order to draw the operation curve of the system find a third pair of x_A - y_A.
