What u need to understand about fractional distillation is that – the crude oil have diffrent size , weight and boiling point and for separating them we use the process fractional distillation ..
I AM EXPLAINING THE METHOD OF THAT HERE , TRY TO DO IT WITH A THERMOCOOL .
FOR DIAGRAM KINDLY REFER TO NCERT
1- HEAT THE MIXTURE OF TWO SUBSTANCES WITH DIFFRENT BOILING POINT TO A HIGH TEMPERATURE .
2- the substance will boil and forming the vapour , most substances will go into vapour phase .
3- the vapour enter into the botom of fractional distillation column .
they have tray which have many holes , and bubble caps , and that will allow it to pass the vapour .
4- the vapour rises in the column .
5- as the vapour rises through the tray it cools down .
6- when a substance in the vapour reaches a height where the temperature of the column is equal to that of the substances boiling point , it will condense to form a liquid .
7- the trey collect the vapour liquid fractions ,
8- the collected liquid may pass in the condenser which cool them further and go to the storage tank , or they go to chemical area for processing .
WHATEVER STEPS I DESCRIBED ABOVE , TRY TO SHOW THAT IN THERMOCOOL PROCESS .
IF FACED ANY PROBLEM STILL , THEN LET ME KNOW ..
ALL THE BEST ..
