A feed mixture of 40% methanol and 60% ethanol is subject to flash distillation at 1atm. The feed is heated to a temperature where 40% of the feed flashes. Draw the T-(x,y) diagram of the feed. What is the boiling point of the feed? What are the vapor and liquid compositions leaving the flash chamber assuming the flash chamber temperature is 3°C above the boiling point of the feed? What is the required feed temperature?
