A liquid stream containing three hydrocarbons is fed to a separation train that separates the mixture into relatively pure components. The feed consists of 45.0% benzene, 31.0% toluene, and the remainder xylene, all on a molar basis. The feed enters a distillation column, and two streams exit. The bottoms stream contains 97.0 mole % xylene and no benzene. 96.0% of the xylene in the feed is recovered in the bottoms stream of the first column. The overhead product from the first column is fed to a second distillation column. The distillate (overhead product) from the second column contains 94.0 mole percent benzene and 96.0% of the benzene fed to the column is recovered in this stream. The balance of the overhead stream is toluene. Flow-Chart and Degree-of-Freedom Analysis I Draw and label a flow chart for the system. Inspect the flow chart and determine the number of components in each system. By inspection of the flow chart and implementation of the constraint that the component mole fractions of each stream must add up to 1 , determine each of the following mole fractions. Assume a basis of 100 mol of feed to the system and perform a degree-of -freedom analysis on column 1, column 2, and the overall svstem. With which system should you begin your calculations in order to proceed most efficiently? Attempts: 0 of 10 used Assume a basis of 100 mol of feed and determine the amounts and component mole fractions for the distillate and bottoms of each column
