Fractional Distilation Flashcards
1
Q
What are the products of fractional distilation?
A
Petroleum gas, Petrol, Kerosene, Diesel Oil, Fuel Oil
2
Q
- Process of fractional distilation: heated crude oil enters a tall
fractionating column
A
,which is hot at the bottom and gets cooler towards the top
3
Q
- Process of fractional distilation: vapours from the oil
A
rise through the column
4
Q
- Process of fractional distilation: vapours
condense when they become cool enough
A
become cool enough
5
Q
- Process of fractional distilation: liquids are led out of the column at
A
different heights
6
Q
Smaller chains of alkenes condense at the top since they
A
rise in the heat
7
Q
Due to their greater mass and volume when the larger chains are deprived of ________ _______ they…
A
heat energy - they condense quickly (at the bottom without rising) and turn to liquid
8
Q
The fractions in the fractionating column are seperated according to….
A
their boiling point
