A continuous fractionating column operating at atmospheric pressure, is to be designed to separate a mixture containing 40% carbon disulfide (CS2 ) and 60% Carbon tetra chloride (CCl4 ) into an overhead product containing 95% w.w CS2 and 97% CCl4 waste. (All weight percent). Complete the material balance around the column? All results should be in mole and mole percent (Not in weight percent). 1. Draw a process flowchart 2. Write balances around the column based on CS2 and CCl4....
