Question

process of fractional distillation with the help of example .

Answer 1

Hello Friend !


Fractional distillation is the separation of a mixture into its component parts, or fractions, such as in separating chemical compoundsby their boiling point by heating them to a temperature at which one or more fractions of the compound will vaporize. It is a special type of distillation. Generally the component parts boil at less than 25 °C from each other under a pressure of one atmosphere (atm). If the difference in boiling points is greater than 25 °C, a simple distillation is used.

EXAMPLE :- used in petroleum refineries, petrochemical and chemical plants, natural gas processing and cryogenic air separation plants.


Hope this helps !!

Answer 2

hello friend!!
let's take the example of petroleum so,,
the crude petroleum is heated around 400°c and introduction into a tower called fractionating column. the column is heated from the bottom. the oil vaporized through the column and cool down it different levels. fractions with high boiling point condenses near the bottom while fractions with low boiling point condenses near the top of the column. some vapor do not condense. they get deposits at the bottom as residue. all products formed during the fractional distillation are very useful........

so this was your answer. hope it will help well
