A 100 kmol/h stream that is 97 mole% carbon tetrachloride (CCl 4) and 3% carbon disulfide (CS2) is to be recovered from the bottom of a distillation column. The feed to the column is 16 mole% CS2 and 84% CCl4, and 2% of the CCl4 entering the column is contained in the overhead stream leaving the top of the column.(a) Draw and label a flowchart of the process and do the degree-of-freedom analysis.(b) Calculate the mass and mole fractions of CCl4 in the overhead stream, and determine the molar flow rates of CCl4 and CS2 in the overhead and feed streams.
