We desire to produce two ethyl alcohol-water mixtures each containing 90% and 50% alcohol by mole from a dilute mixture containing 20% mole alcohol by distillation. 98% of the ethyl alcohol in the feed is to be recovered in these two products, that is, only 2% of the ethyl alcohol in the feed may go into the bottoms. If the bottoms contain 0.6% alcohol, calculate the amount of the different streams.

Question

We desire to produce two ethyl alcohol-water mixtures each containing 90% and 50%
alcohol by mole from a dilute mixture containing 20% mole alcohol by distillation. 98%
of the ethyl alcohol in the feed is to be recovered in these two products, that is, only 2% of
the ethyl alcohol in the feed may go into the bottoms. If the bottoms contain 0.6% alcohol,
calculate the amount of the different streams.
