Problem 2.1: (15 marks) An ethanol-methanol-propanol stream is fed at the rate of 2000 kg/h to a distillation column. Feed is 20% methanol. Ninety percent of the methanol is to be recovered in the distillate along with 60% of ethanol. All of the 400 kg/h of propanol fed to the process must be sent to the bottom. Draw and label the process flow diagram and perform a degree of freedom analysis
