Making Crude Oil Useful: Fractional Distillation and …
2012-1-22 · Fractional Distillation: Step-by-Step. Crude oil is vapourised and fed into the bottom of the fractionating column. As the vapour rises up the column, the temperature falls. Fractions with different boiling points condense at different levels of the column and can be collected. The fractions with high boiling points (long chain hydrocarbons
Produce pure ethanol with an efficient fractional …
An efficient distillation process is extremely important to produce ethanol or alcohol that is totally pure and safe to consume. However, since many substances other than ethanol also vaporize at roughly the same temperature, you will certainly need an efficient fractional distillation column to separate the desired ethanol from undesired

How Separation Works in Column Chromatography Methods
2016-8-29 · Separation in column chromatography relies on differences. Molecules vary in size, charge, polarity, and solubility. We leverage these differences to distribute molecules between a stationary phase and a mobile phase. But because molecules are so different, it’s not possible to have a single method that works for all.
