You are required to design a binary distillation column to separate a mixture at a constant 1 atm pressure. The feed flow rate is 100 kmol/h, containing 30% A and 70% B. The goal is to design a distillation column in such a way that 95% of the A is recovered as a top product with 90% purity.The unit contains a total condenser and a partial reboiler. The average latent heat of the mixture can be assumed to be 40 kJ/mol. The relative volatility for the system = 1.7. Determine the flow rate and composition of the products.
