An equimolar mixture of ethane, propane, n-butane, and n-pentane is subjected to a flash vaporization at 150°F and 205 psia. What are the expected amounts and compositions of the liquid and vapor products? Is it possible to recover 70% of the ethane in the vapor by a single-stage flash at other conditions without losing more than 5% of nC4 to the vapor? Obtain K-values fromFigure.
