Fractional distillation is the most common method of separating the components of crude oil. This process is effective because the miscible components differ in boiling points. Crude oil is heated so that a component is converted to a gas. The vapour then passes up a fractional distillation column which contains ‘trays’. When the substance of the vapour reaches a certain part of the fractional distillation...
