Fractional distillation

HideShow resource information

Fractional distillation

Short chain hydrocarbons

  • Usefull
  • Low boiling point
  • Flamable
  • Low viscosity (how easily it flows)
  • High volality (how easily it turns into a gas)

Long chain hydrocarbons

  • Not usefull
  • Not very flamable
  • High viscosity
  • Low volality (how easily it turns into a gas)

We can seperate the fractions of crude oil by using fractional distillation.

  • Vapourised crude oil is fed into the bottom…
