A mixture containing 42% benzene and 58% toluene by mass is fed to a distillation column. A second mixture is also fed to the distillation column and has a composition of 65% toluene and 35% acetone by mass. The flowrates of the mixtures are 2500 kg h1 and 1500 kg h1 respectively. An overhead distillate exit stream of 800 kg h-1 containing 23% acetone and a bottom exit stream of 25% benzene are produced. Determine the bottom exit flowrate and...
3(65) A stream enters distillation tower #1 containing methanol (M), ethanol (E), and water (W), with composition as shown on next page. A vapor stream leaves tower #1, with total flow rate of 100 mols, containing 90 mol% M and 10 mol% E. No water leaves in this vapor stream. The liquid stream leaving tower #1 contains only ethanol and water (no methanol), and is fed to tower #2, 90% of the water in the feed to tower #2 leaves...
