The feed (17000 kgmole) to a distillation column is a 55.0 weight % CH3OH – 45.0 weight % water (nonvolatile) liquid mixture. The water stream leaving the bottom of the column, which contains 96.0 mole % water. The liquid stream leaving the bottom of the column goes to a reboiler. Part of the stream is vaporized; the vapor is recycled to the bottom of the column as boilup, and the distillate liquid is withdrawn as top product as 9582 kgmoles.
(i) Draw the distillation column and mention the streams.
(ii) Calculate the percentage moles of volatile component in the
distillate. Given Atomic weight Carbon -12 g/g-atom, Hydrogen – 1 g/g- atom.
b. 8 barrels per metric ton is used for the storage of North Sea Crude oil. Calculate the density of North Sea crude oil in lb/gallon and classify the type of oil.
