A mixture containing 20 mole % butane, 35 mole % pentane and 45 mole % hexane is to be separated by fractional distillation into a distillate product with a composition 95 mole % butane, 4 mole % pentane and 1 mole % hexane, and a bottoms product. The recovery of butane in the distillate must be 90%. Determine the composition of the bottoms product.

mixture of 45 mole% n-hexane and 55 mole % n-heptane is subjected to continuous fraction in a tray column at 1 atm total pressure. The distillate contains 95% n-hexane and the residue contains 5% n-hexane. The feed is saturated liquid. A reflux ratio of 2.5 is used. The relative volatility of n-hexane in mixture is 2.36. Determine the number of ideal trays required.

You separated a mixture containing 20 wt% CH3OH, 35 wt% C2H5OH, and the balance water into two fractions. You then drew and analyzed samples of both product streams and reported that one stream contained 42.2% CH3OH and 29.3% C2H5OH and the other stream contained 16.5% CH3OH and 45.2% C2H5OH. After examining the report your professor indicated that the results must be wrong and asked you to repeat the stream analyses. Show why the professor is right
