Steam Distillation vs. Fractional Distillation: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Published on January 11, 2024
Steam distillation separates heat-sensitive substances using steam, while fractional distillation separates mixtures based on boiling point differences.

Key Differences

Steam distillation is used to extract volatile compounds from heat-sensitive materials, typically in the essential oil and fragrance industries. Fractional distillation involves separating a mixture into its component parts or fractions, based on different boiling points, commonly used in petroleum refining and alcohol production.

In steam distillation, steam is passed through the plant material, vaporizing the volatile compounds which are then condensed and collected. In fractional distillation, the mixture is heated, and components with lower boiling points are vaporized and separated first.

Steam distillation is particularly effective for substances that are immiscible with water and have high vapor pressures. Fractional distillation requires a fractionating column for the separation process, which is absent in steam distillation.

The application of steam distillation is limited to substances that are stable at high temperatures. Fractional distillation is more versatile and can be used to purify complex mixtures like crude oil into its constituents like gasoline, diesel, etc.
