Find acetonitrile-water vapor-liquid equilibrium data at 1 atm in the following paper: blackford, d. s; york, r. (1965). vapor-liquid equilibria of the system acrylonitrile-acetonitrile- water. j. chem. eng. data 10,313-318. (a) plot the vapor-liquid equilibrium data for the acetonitrile-water system as a y-x plot. (b) if the acetonitrile vapor mole fraction is 0.58 in a flash drum operating at 1.0 atm, what is the acetonitrile liquid mole fraction? (c) what are the values (y/x) at 1.0 atm for acetonitrile and water at an acetonitrile liquid mole fraction of 0.20? (d) if a feed containing 40.0 mol% acetonitrile is introduced to a flash distillation reactor operating at (v/f) = 0.65 and 1.0 atm, what is the temperature of the flash drum? what are the vapor and liquid phase mole fractions of acetonitrile?
