![A mixture of dichloromethane (1) and ethyl acetate (2) and is separated in a flash drum at 1 bar.
a) The flash drum is operated such that the liquid mole fraction is 33 mol % dichloromethane,
liquid product rate is 500 kmol/h, and 19.5 % of the feed is vaporized. What must the feed
flowrate and composition of the feed be?
b) The flash drum is operated such that the vapor mole fraction is 81 mol % dichloromethane,
vapor product rate is 1750 kmol/h, and 70 % of the feed is vaporized. What must the feed
flowrate and composition of the feed be?
c) The feed composition is 35 mol% and the drum temperature is 67 °C. Find the fraction of feed
vaporized and the composition of the liquid and vapor products.
