Question 7

how crude oil is separated?

Answer 7

1. oil is heated. most turns into gas and the bitumen stays liquid and it’s drained off at the bottom.
2. in column there’s a temp gradient. hot at bottom, and gets cooler as you go up). when a substance reaches the temp that is lower than their boiling point they condense.
3. longer hydrocarbons have higher boiling points, they condense early on.
4. shorter hydrocarbons have lower boiling point, they condense later on.
5. bubble caps in column stop the separate pd liquids from going back into the column and remixing.
