QUESTION 3: Table 1 shows the mixture of components to be separated for a design of mutioonponent distilation column. The rate of 100kmolh feed entering to the disblasion column b saturated liquid. The reflux ratio is 1.2 times the minimum refux, where the minimum nofux is 0.489 and the value of =14.70. The overal column efficiency E0 is 85%. The androg relative volatility for each of the component with hexane taken as the reference componens also given Table 2 Based on the data given, design the distillation column by the following sequence: a) Calculate the mol fraction for feed, distilate, and bottom in Table 1 (3 marks) b) Determine the minimum number of stages. (3 marks) c) Determine the number of theoretical stages and actual stages (7 marks) d) From data given in Table 2, estimate the column height and column diameter at 85\% of flooding velocity. (Consider the downcemer area is 12% of total) (12 marks)
