Test: Distillation Types - Question 1

In Azeotropic distillation __________ remains low.

Detailed Solution for Test: Distillation Types - Question 1

Explanation: Same vapour pressure of the mixture has nearby volatility.

Test: Distillation Types - Question 2

Find the distillation preferred for the binary mixture having component A and B with vapour pressure 360mmHg and 355mmHg.

Detailed Solution for Test: Distillation Types - Question 2

Explanation: Relative volatility = Vapour pressure of A/ Vapour pressure of B
= 360/355 = 1.014 ( Azeotropic composition).

Test: Distillation Types - Question 3

The term entrainer used in

Detailed Solution for Test: Distillation Types - Question 3

Explanation: Entrainer increase the relative volatility.

Test: Distillation Types - Question 4

By adding Entrainer the __________ azeotropes forms.

Detailed Solution for Test: Distillation Types - Question 4

Explanation: Since when we add entrainer the relative volatility increases by formation of low boiling azeotropes.

Test: Distillation Types - Question 5

The use of solvent for increasing the relative volatility is for

Detailed Solution for Test: Distillation Types - Question 5

Explanation: Generally, solvent is used for extraction. As it help to alter the relative volatility it is used in extractive distillation.

Test: Distillation Types - Question 6

 In the distillate use of heat is to separate the distillate from the entrainer.

Detailed Solution for Test: Distillation Types - Question 6

Explanation: See, in Azeotropic distillation the overhead products will be composed of entrainer added. In order to pure product heat is given to the distillate product.

Test: Distillation Types - Question 7

Find the Azeotropic mixture.

Detailed Solution for Test: Distillation Types - Question 7

Explanation: Acetic acid- water mixture has the nearby same boiling point.

Test: Distillation Types - Question 8

If the feed mixture has the same vapour and liquid compositions at equilibrium then the distillation is normal.

Detailed Solution for Test: Distillation Types - Question 8

Explanation: If the liquid and the vapour compositions are same the relative volatility becomes 1 and there must be an azeotropes formation.

Test: Distillation Types - Question 9

Will it possible to separate the mixture having relative volatility value 2 with azeotropic distillation.

Detailed Solution for Test: Distillation Types - Question 9

Explanation: Because if the relative volatility is 2 there will be a large difference in vapour pressure so there won’t be any Azeotropic formation.

Test: Distillation Types - Question 10

By adding entrainer or solvent one of the component’s _________ gets reduced.

Detailed Solution for Test: Distillation Types - Question 10

Explanation: By adding entrainer or solvent the relative volatility increased due to decrease in the boiling point of one component.
