Task 2 (Consumption of the cubic remainder)

In a continuous distillation column, 340 kmol/h of the water - acetic acid mixture is accelerated under atmospheric pressure. The ordinate of the intersection point of the working lines is 0.48. The equation of the working line of the upper part of the column is y = 0.84 x + 0.15. The flow rate of the vapor phase entering the dephlegmator for condensation is 550 kmol/h. Determine the mass consumption of the cubic residue (bottom product) and the mass fraction of acetic acid in it. Explain the course of the decision and the results obtained.
