1. A 60kmol/h liquid solution which is at 25C, contains 32mol percent ethylene glycol and 68mol percent water. This solution will be flash- distilled at 1.013 bar constant_pressure. For a fractional vaporization of 0.50 , calculate: a) The compositions of top and bottom products, b) The flash temperature, c) The percentage recovery of ethylene glycol. (Hint: Draw t-xy and x-y diagrams of the water- ethylene glycol system using the data table below. x refers to mole fraction of water in liquid and y refers to mole fraction of water in vapor.)
