Distillation

Question 1

Principle

Answer 1

Is to separate liquid mixtures and purify from each of the substances by boiling and condensing.

Question 2

Reboilers

Answer 2

Bottom product that is not taken off as product is reintroduced through the reboiler where it is heated to its desired temperature.

Question 3

Side strippers

Answer 3

A stripper is basically a smaller distillation tower that is used to strip lighter products from side-draw products

Question 4

Reflux

Answer 4

vapor that leaves the top of the column is condensed and split by a reflux divider as top product or reflux, which is then reintroduced into the top of the column cooling the top of the tower

Question 5

Temperature gradient

Answer 5

Can be achieved by carefully controlling reflux and reboiler temperature. Both top and bottom of the column should meet the materials required boiling temperature
