3 A 5 Kg Min Stream Of Liquid Ethanol Water At 40 C Containing 30 W W Of Ethanol Will Be Heated And Separated In An A 1 (20.4 KiB) Viewed 19 times

3. A 5 kg/min stream of liquid ethanol-water at 40 °C containing 30% w/w of ethanol will be heated and separated in an adiabatic flash distillation drum at 98 kPa. If the desired composition of the vapor is 60% w/w of ethanol: (a) (5 points) What will be the composition (w/w fraction or %) of the liquid at the bottom? (b) (5 points) What will be the temperature (°C) in the drum? (c) (10 points) What will be the mass flow rates (kg/min) of vapor and liquid streams leaving the unit? (d) (20 points) Assuming there is no heat loss in the drum (adiabatic) and the streams are in thermodynamic equilibrium. What is the amount of heat required (kW) to perform this operation? H-z-y diagram for the system Ethanol-Water is presented in page 2 of this assignment.
