Explanation: The rectifying section where the high volatile components are stripped from the liquid condensed.

Test: Continuous Operation Of Distillation Column - Question 7

Express the reflux ratio

Detailed Solution for Test: Continuous Operation Of Distillation Column - Question 7

Explanation: The reflux ratio is the ratio of reflux(R) to the Distillate(D).

Test: Continuous Operation Of Distillation Column - Question 8

The use of vapour produced from the reboiler is

Detailed Solution for Test: Continuous Operation Of Distillation Column - Question 8

Explanation: The vapour from the stripping section strips the more volatile component to form distillate.

Test: Continuous Operation Of Distillation Column - Question 9

The light key components are__________

Detailed Solution for Test: Continuous Operation Of Distillation Column - Question 9

Explanation: Since the light key components have low boiling point it is a more volatile component.

Test: Continuous Operation Of Distillation Column - Question 10

Find the reflux ratio if the feed , residue and reflux rate is 100, 40 and 50 mole/hr.

Detailed Solution for Test: Continuous Operation Of Distillation Column - Question 10

Explanation: Reflux ratio = reflux/distillate
Distillate= 100-40=60
Reflux ratio= 50/60 = 0.83.
