In absorption there is one component will transfer to the other component ex:ammonia can absorbed by water but at a time there is no two components will not absorb because in their chemical and physical properties.

Absorption is used for separation of Gas mixture, while crystallization, extraction and evaporation are used for separation of Liquid mixture.

Which is the correct answer?

Vijay Jethwa said: (Sep 1, 2017)  
I think Fractional Crystallization is the correct answer.

Absorption only use for gas liquid operation.

If we use gas absorption during operation two components remove H2s and CO2 so how can you say one component remove?

Why not osmossis, reverosmossis and dialysis? Please explain it in detail.

Vaibhav said: (Jan 16, 2020)  
The only absorption is there in option which is not liquid separation unit operation.

Rajendra Pal said: (Jan 20, 2020)  
Absorption is the transfer of one or more material from gas phase to liquid solvent so absorption is the correct option.

The answer is C.

Because the absorption is used for separation by leaching, extraction, etc process.
