Flashcards in Fractional Distillation Deck (12):
1

Describe the process of fractional distillation

- the oil is heated until most of it is gas, these gases enter a fractionating column
- longer hydrocarbons have high boiling points, so condense at the bottom
- shorter hydrocarbons have low boiling points,
So turn into liquid much later on at the top

2

What stops the liquid running back down into the next fraction

Bubble caps

3

What decreases as you go up the column

- viscosity decreases
- boiling point decreases

4

Describe refinery gases

- 3HDC
- bottled gas
- heating

5

Describe Gasoline

- 8 HDC
- fuel for cars

6

Naphtha

- 10 HDC
- dyes
- plastics

7

Describe Kerosene

- 15 HDC
- jet fuel
- heating

8

Describe diesel

- 20 HDC
- fuel for Diesel engines

9

Describe fuel oil

- 40 HDC
- fuel for ships
- heating

10

Describe bitumen

- 70+ HDC
- road surfacing
- roofing
