Fractional Distillation

Question 0

Why do we use fractional distillation in crude oil?

Answer 0

Because it separates the crude oil into groups (fractions) of compounds of similar boiling points.

Question 1

What does FRACTIONAL and DISTILLATION mean?

Answer 1

Fractional- groups of compounds with similar boiling points

Distillation- uses different boiling points of compounds to separate mixtures

Question 2

What is distillation?

Answer 2

Heating/ evaporating and then cooling, compounds can be separated by using their different boiling points.

Question 3

What is crude oil?

Answer 3

Mixture of many compounds (hydrocarbons- hydrogen and carbon)

Answer 4

1) c5-c9 (coolest) , cars & trucks
2) c16-c30 (hottest) , ships, industrial heating & oil fired power stations
