Flashcards in Crude oil Deck (16):
1

what is crude oil?

a mixture of hydrocarbons

2

how is crude oil made?

-oil is heated until a gas
-gases enter fractioning column
-longer hydrocarbons have high boiling points
-they condense near the bottom

3

where is crude oil made?

in a fractioning column

4

what do the bubble caps do?

they stop the separated liquids from running back down the column and remixing

5

give the order of fractions from the top, down

refinery
gasoline
naphtha
kerosene
diesel
fuel oil
bitumen

6

refinery gas

-bottled gas
-heating
-pottery and glass manufacture

7

gasoline

fuel for cars

8

naphtha

-chemical industry to make: plastics, dyes, drugs, explosives, paints etc

9

kerosene

-jet engines
-domestic heating

-fuel for diesel engines in cars, trucks, trains, boats etc

11

fuel oil

-domestic central heating
-fuel for big ships

12

bitumen

-road surfacing
-asphalt for roofs

13

fractional distillation produces more... and fewer...

long-chain hydrocarbons, short-chain hydrocarbons

14

long chain hydrocarbons have...

-high boiling points
-are viscous

15

what is cracking?

a form of thermal decomposition

16

conditions for cracking:
