What is the purpose of fractionating or distillation towers in the refining process of crude oil?
What is the purpose of fractionating or distillation towers in the refining process of crude oil?
- To chemically alter the compounds in the original oil
- To separate crude oil into various fractions based on molecular weight (correct)
- To convert separated fractions into product streams
- To increase the boiling point of the crude oil
What happens as the vapour in the distillation column rises?
What happens as the vapour in the distillation column rises?
- The vapour continues to rise as it bubbles through barrier trays (correct)
- The liquid is heated to increase its molecular weight
- The temperature drops above the boiling point of certain components
- The vapour is immediately condensed into liquid phase
