a) Draw a schematic of binary distillation column and annotate
it appropriately to include feed, distillate and bottoms flowrates
and compositions, equilibrium stages, feed stage, reboiler stage
and reflux ratio.
b) State the vapour and liquid compositions entering and leaving
the feed stage.
Why do we need to maintain liquid level in the bottom of
distillation column? (also liquid level in accumulator)? Is there
relation between maintaining liquid level in the bottom of
distillation column with operability of kettle reboiler?
CCC Shop is considering a project to improve their production
efficiency. They are trying to decide whether it is a good idea or
not to buy an automated injection molding machine which will result
in reducing pre-tax costs by $500,000 for each of the next three
years. The molding machine will cost $1,000,000 and the IRS says it
must be depreciated as 3-year MACRS equipment. CCC Shop believes
they can sell the machine for $80,000 at the end of three...
Reactor Systems and Separation Systems
Please explain how to break a flood on a distillation
column.
Explain how the temperature is controlled on the
- top
- middle
- bottom part of the tower,
in a distillation column
6. Distillation: Why do we need reflux to return back to
distillation columns? How the reflux ratio will affect the design
and operations of distillation process.
