 · The first is to have the reactor operate such that greater than 75% acetone is present in the outlet stream. This way, you can run the column/flash drum at 10 atm, and perform the separation from 75%->99% past the azeotrope. Try exploring pressures at above 10 atm also - the location of the azeotrope might go below 75% acetone.
