A mixture of heptane/decane at 1.8 bar, 120?C contains 80% by mol heptane. At what pressure should it be flashed to obtain a stream that is 90% rich in heptane? What are the composition of the liquid and the amounts of the two phases? Please show all work and equations used for full stars, answers without explanation yield 1 star rating.
