Answer:

The first part of refining crude oil is to heat it until it boils. The boiling liquid is separated into different liquids and gases in a distillation column. These liquids are used to make petrol, paraffin, diesel fuel etc. ... The gases cool down as they go up the column until they condense (turn back into liquid again).
