The oil refining process starts with a fractional distillation column.; ... Different hydrocarbon chain lengths all have progressively higher boiling points, so they can all be separated by distillation. This is what happens in an oil refinery - in one part of the process, crude oil is heated and the different chains...

The boiling point is especially important because, since liquids change their states at different temperatures, those in a mixture can be separated from one another by raising the temperature of the mixture gradually so that each component ...

Distillation is a physical process used to separate mixtures that contain at least one liquid. Distillation works because each substance in the mixture has its own unique boiling point. ... This is known as a fractional distillation. Crude oil, a mixture of many substances including a number of liquids, is refined in this way.

Distillation can be used to separate volatile liquids by a process known as fractional distillation. In this procedure, the liquid mixture is placed in the flask of a distillation apparatus. As the flask is heated, the lower boiling liquid vaporizes faster than the higher boiling liquid.

Fractional distillation is used to separate mixtures of miscible liquids, such as ethanol and water. The process depends on the components of the mixture having different boiling points. The liquid is heated so that it turns into a gas.
