Question

It is desired to separate a mixture of methanol and water in a flash vessel at 1 atm pressure.The table below presents the methanol-water equilibrium data at 1 atm, where x represents composition of methanol in the liquid and y its composition in the vapor (both on a molar basis).
The figures below are the representation of these equilibrium data in graphical form.
a) If the feed is 60 mol% methanol and 40% of the feed is vaporized, what are the mole fractions and flow rates of liquid and vapor? The feed is 100 kmols/h. . What is the drum operating temperature?
b) If the feed has 30 mol% methanol and the liquid product must have 20 mol% methanol what should be the vaporized fraction for the 1000 kmol/h feed? Calculate the flow rates and compositions of the products.
Size the drum of item b considering that the density and molecular mass of water is 1 g/mL and 18 g/mol, of methanol 0.7914 g/mL and 32 g/mol and the vapors are ideal gases.
