A distillation column is designed to separate a mixture of multicomponent as shown in Table 1. The feed enters the column at its saturated liquid at a rate of 100kmol/h. The reflux ratio is 1.2 times the minimum reflux, where the minimum reflux is 0.489 and the value of =14.70. The overall column efficiency is 85%. The average relative volatility for each of the component with hexane taken as the reference component also given in Table 1. "Average relative volatility of components was calculated using the distribution coefficient with the last component taken as the reference component. Estimate the column height and column diameter at 85% of flooding velocity. (Consider the downcomer area is 12% of total area). Figure 11.27. Flooding velocity, sieve plates
