As there is a lot of confusion between the terms fractional distillation and simple distillation, so many people consider it the same term with a different name. Well, I can tell you that they are not similar they perform a different function and have different features.
It is the method of separating the mixture into its fractions or part. This is the process in which chemical compounds are part of the boiling to a temperature from which one or more fraction of the mixture will evaporate. It is the method that uses distillation to fractionate.
Simple distillation is the process from which two liquids with the different boiling temperatures can be split-up. It is the method that can be used to part the liquid, which has at least fifty degrees difference in their boiling temperature. Water distillation is one of the examples of simple distillation.
Fractional Distillation vs Simple Distillation
The main difference between fractional distillation and simple distillation is the fractional distillation used a mixture containing chemicals to separate, which have boiling temperatures close to each other. On the other hand, simple distillation is used to separate substances in a mixture that has fifty degrees difference in their boiling nature.

| Boiling point | Fractional distillation can separate the mixture, which has boiling points close to each other. | Simple distillation can separate the mixture fifty degrees difference in their boiling nature. |
| Example | Fractional distillation is used for crude for refining. | Simple distillation is used to purify seawater. |

What is Fractional Distillation?
Federal distillation is the process of separating chemical compounds from each other when the boiling temperature difference is less than forty degrees. This process completes several simple distillations in one apparatus.
It is mainly packed in a metal wire, glass beads, or metal ribbon, which give an extra condensing surface to the distillation process. This process makes sure that the condensation teaches to its final condenser as soon as possible. One example of fractional distillation is the crude oil that is split up in various components.
Fractional distillation used a fractionating column because the liquid mixture in the method has a kind of the similar boiling point. The fractionating column acts as a hurdle to the raising gas. It will stop not such a pure condensation from passing through it. The gas creates in the packing material in the fractionating column and will be again warmed up by the hot gas that will evaporate again unless it becomes pure.
What is Simple distillation?
Simple distillation is the method of splitting up two-component which have a different boiling point. It can split up the liquids which have at least fifty degrees different boiling point. Thus, the liquid being distilled is heated, the condensation that forms will be the richest in the mixture that warm-up at the low temperature.
Refine compounds will be warm-up and turned into condensation at a relatively low-temperature range 2 or 3 degrees Celsius; by looking at the distillation flask’s temperature, it is possible to affect a good split up in the compound. Thus the distillation progress, the concentration to the lowest component, will regularly decrease.
The machine temperature will start to change; thus, a pure compound is no longer being distilled. The temperature will be increasing until the boiling point of the next lowest boiling compound comes near. When the condition again gets stabilized, another pure fraction of the distilled could be collected. This fraction that can be distillate will be the compound that warms up at the second-lowest temperature. This process of simple distillation will continue until the original mixture is separated. The simple distillation is the process best for liquid, which has a different boiling point.
Main Differences Between Fractional Distillation and Simple Distillation
- Both, simple and fractional distillation processes are all about splitting up different properties of liquids.
- If two or more liquids have a close boiling point to each other then we can separate them by fractional distillation, on the other hand, simple distillation is the process of separating liquid, which has a fifty-degree difference boiling point.
- Fractional distillation uses complex equipment with a fractionating column, but on the other hand, simple distillation uses simple equipment with a fractionating column.
- In fractional distillation, the process has to be done many times to get a pure component. On the other hand, a simple distillation process does not have to be repeated several times.
- In fractional distillation, we cannot use split up solvent from a solute. On the other hand, simple distillation can use a split up solvent from a solute.
- This process of Fractional distillation is used typically for crude oil refining. On the other hand, the process of simple distillation is used to purify seawater.
Conclusion
As the difference between fractional distillation and simple distillation has been pointed out, it is clearly understood that they are very much different from each other.
As the fractional distillation and simple distillation, both are the process to separate mixture from the compound, but they both perform the process differently.
